The Volkswagen Beetle—officially the Volkswagen Type 1—is an economy car that was built by the German company Volkswagen (VW) from 1938 until 2003. It has a rear-engine design with a two-door body style and is intended for five occupants (later, Beetles were restricted to four people in some countries).
The need for a people's car (Volkswagen in German), its concept and its functional objectives were formulated by the leader of Nazi Germany, Adolf Hitler, who wanted a cheap, simple car to be mass-produced for his country's new road network (Reichsautobahn). Members of the National Socialist party, with an additional dues surcharge, were promised the first production, but the Spanish Civil War shifted most production resources to military vehicles to support the Nationalists under Francisco Franco.
Lead engineer Ferdinand Porsche and his team took until 1938 to finalise the design. Béla Barényi is credited with conceiving the original basic design for this car in 1925, notably by Mercedes-Benz, on their website, including his original technical drawing, five years before Porsche claimed to have done his initial version. The influence on Porsche's design of other contemporary cars, such as the Tatra V570, and the work of Josef Ganz remains a subject of dispute. The result was the first Volkswagen, and one of the first rear-engined cars since the Brass Era. With 21,529,464 produced, the Beetle is the longest-running and most-manufactured car of a single platform ever made.
Although designed in the 1930s, due to World War II, civilian Beetles only began to be produced in significant numbers by the end of the 1940s. The car was then internally designated the Volkswagen Type 1, and marketed simply as the Volkswagen. Later models were designated Volkswagen 1200, 1300, 1500, 1302, or 1303, the first three indicating engine displacement, the last two derived from the model number.
The car became widely known in its home country as the Käfer (German for "beetle", cognate with English chafer) and was later marketed under that name in Germany, and as the Volkswagen in other countries. For example, in France it was known as the Coccinelle (French for ladybug).
The original 18.6 kW (24.9 hp) Beetle was designed for a top speed around 100 km/h (62 mph), which would be a viable cruising speed on the Reichsautobahn system. As Autobahn speeds increased in the postwar years, its output was boosted to 27 kW (36 hp), then 30 kW (40 hp), the configuration that lasted through 1966 and became the "classic" Volkswagen motor. The Beetle gave rise to multiple variants: mainly the 1950 Type 2 'Bus', the 1955 Karmann Ghia, as well as the 1961 Type 3 'Ponton' and the 1968 Type 4 (411/412) family cars, ultimately forming the basis of an entirely rear-engined VW product range.
The Beetle marked a significant trend, led by Volkswagen, and then by Fiat and Renault, whereby the rear-engine, rear-wheel-drive layout increased from 2.6 percent of continental Western Europe's car production in 1946 to 26.6 percent in 1956. In 1959 even General Motors launched an air-cooled, rear-engined car, the Chevrolet Corvair—which also shared the Beetle's flat engine and swing axle architecture.
Over time, front-wheel drive, and frequently hatchback-bodied cars would come to dominate the European small-car market. In 1974, Volkswagen's own front-wheel drive Golf hatchback succeeded the Beetle. In 1994, Volkswagen unveiled the Concept One, a "retro"-themed concept car with a resemblance to the original Beetle, and in 1998 introduced the "New Beetle", built on the contemporary Golf platform with styling recalling the original Type 1. It remained in production through 2010, and was succeeded in 2011 by the Beetle (A5), the last variant of the Beetle, which was also more reminiscent of the original Beetle. Production ceased altogether by 2019.
In the 1999 Car of the Century competition, to determine the world's most influential car in the 20th century, the Type 1 came fourth, after the Ford Model T, the Mini, and the Citroën DS.[
Nicosia ( Greek : Λευκωσία (Lefkosia), English : Nicosia), located in the middle of the island of Cyprus , is the capital of the Republic of Cyprus and the Turkish Republic of Northern Cyprus . It is the most populous city of Cyprus and the most important cultural, industrial, trade and transportation center. Nicosia is located at 35°10' north, 33°21' east.
The city is divided into two by the border called the Green Line . Although de jure the Republic of Cyprus has the administration of the entire city, de facto it only has control over South Nicosia . Northern Nicosia is under the rule of the Turkish Republic of Northern Cyprus and is considered to be under Turkish occupation by the international community. The two sectors are separated by a Buffer Zone administered by United Nations Peacekeeping Forces . With the 1960 Constitution of the Republic of Cyprus, the Turkish Municipality of Nicosia was granted legal status.
Nicosia is known as "Lefkosia" (Λευκωσία) in Greek and "Nicosia" in English .
The first name of the area where the city is located was "Ledra". This name is also written as "Ledrae", "Lidir", "Ledras", "Ledron" and "Letra". Later, this city was destroyed and when it was rebuilt by Leucus, the city was named "Lefkotheon" (Λευκόθεον - city of the white gods). This name was also occasionally referred to as "Ledron". Later, the words "Kermia" and "Leucus" (Λευκούς) were used for the city. In the 7th century, Hierocles, a Byzantine geographer, mentioned the city as Lefkousia (Λευκουσία) in his book Synekdemos (Vademecum) . In the 13th century , the Patriarch of Constantinople referred to Nicosia as Kalli Nikesis (Καλλι Νίκησις - Beautiful Victory). A writer and monk, St. Neophytos referred to Nicosia as "Leucopolis" (Lefkopolis - White City) in a sermon he gave around 1176. Since the 10th century, the name "Nicosia" has become generally accepted. In the 18th century, Greek Cypriot historian Archimandrite Kyprianos stated that another name for Nicosia was "Photolampos" (Shining with Light).
There are various claims that the city is referred to as "Nicosia" and similar forms in European languages. According to one claim, the Latins replaced the first syllable of the word, "Lef", with "Ni" because they could not pronounce it. Another claim is that the name derives from the name "Kallinikesis". A writer from Sicily named Sindaco connects the name "Nicosia" to the town named "Nicosia" in Sicily and claimed that King Tancred from this town was with Richard I during the siege of Cyprus and named the city after his own town. . Another claim is that the name "Nicosia" emerged during the rebellion of the city's people against the Knights Templar in 1192. A German priest named Ludolf named the city "Nycosia" between 1341 and 1363. HAS Dearborn, in his book published in 1819, says that another name for Nicosia is "Nicotia". In 1856, William Curry stated that the Greeks called the city "Escosie" and the Western Europeans called it "Licosia".
The name of the city is mentioned in Ottoman documents as "Nicosia" or "medine-i Nicosia" . In addition, in a letter regarding the conquest of Nicosia in 1570, the name of the city is mentioned as "Nicosia". Kâtip Çelebi refers to the city as "Nicosia" (which is sometimes used today).
The first settlement in the area where Nicosia is located took place in the Neolithic Age . The date of the first settlement is approximately 3000-4000 BC. In 1050 BC or in the 7th century BC, a city called " Ledra " was founded in the region. This city had an important place among the other city kingdoms on the island. During archaeological excavations, a Greek inscription written in the 4th century BC was found indicating the existence of a temple dedicated to Aphrodite in Ledra. By around 330 BC it had shrunk to a small village. When this city was destroyed due to earthquakes , in 200 BC, Leucus, the son of Ptolemy I Soter , founded the city that is today Nicosia.
The city's importance began to increase in the late Byzantine period. In the 7th century, it became the capital of the island during the Arab raids.
It fell into the hands of Richard I in 1191 . It was the capital of the island during the period when the Knights Templar purchased and dominated the island. A rebellion broke out in the city on 11 April 1192. The knights suppressed this uprising with a massacre and then left the island.
The Lusignans purchased the island and Nicosia remained their capital. During the Lusignan period, he built many new buildings in the city. During the Venetian period, most of these were demolished and used in the construction of walls. During this period, the Lusignans also built walls around the city. These walls were in the shape of an irregular pentagon . There were no walls in the city before. King Henry I built the first walls with two towers in 1211, Peter I built a third tower, and Henry II built the first walls. Henry had the city completely surrounded by walls. The city became quite wealthy during this period. Nicosia was one of four dioceses on the island. It also became the center of an archdiocese in 1212. During this period, events were taking place between Greeks and Latins, and bloody conflicts broke out in the city in 1313 and 1360.
Nicosia has been damaged by many earthquakes throughout its history. The 1222 Cyprus earthquake was felt strongly in the city and caused great damage. In November 1330, a flood occurred in the city and three thousand people lost their lives. In addition, the city was heavily damaged by the Genoese in 1373 and the Mamluks in 1426.
On February 26, 1489, Nicosia, along with the entire island, came under the rule of the Republic of Venice . Just before the Ottoman conquest of the island, the Venetians inspected the walls and found them too weak. According to the new plans, the walls of Nicosia were reduced from eight miles to three miles. Meanwhile, all buildings outside the new walls were destroyed. According to a claim, the route of Kanlıdere was changed by the Venetians. Another claim is that the Ottomans changed the route of the stream to save the city from floods.
During the conquest of Cyprus by the Ottomans , Nicosia was the third largest settlement taken. Piyale Pasha and his army took action to take Nicosia on 22 July 1570. On July 25, Nicosia was besieged. Clashes began on July 27, as the Venetians did not accept the Ottomans' demands to surrender the castle. The fact that the walls were very strong ensured that Nicosia would not fall. At dawn on 9 September 1570, a new attack was launched and troops of more than 20 thousand people conquered Nicosia.
As part of the settlement of Turks in Cyprus during the Ottoman period, the settlement of the Turkish population in Nicosia, as well as in the entire island, started in 1572. Non-professional Greeks in the city were settled in the neighborhoods outside the city and replaced by Turks. According to a census made during this period, the city had 31 neighborhoods. In two of them ("Ermiyan" and "Karaman"), the Armenian population was in the majority.
During the Ottoman period, Nicosia first served as the capital of the State of Cyprus as the center of a district called "Mountain Kaza", and later became a sanjak . During the Ottoman period, St. Large churches such as the Sophia Cathedral were converted into mosques. Nicosia - Larnaca road was built. The gates of the city were opened at sunrise and closed at sunset. The Governor, Judge, Interpreter and Greek Archbishop resided in Nicosia. William Kimbrough Pendleton states that in 1864 most of the houses in the city were made of clay brick. As a result of a major earthquake in 1741, one minaret of the Selimiye Mosque collapsed and had to be rebuilt. There were riots in the city in 1764 and 1821.
On July 12, 1878, Nicosia, along with the rest of the island, came under British rule . British troops entered the city through the Kyrenia Gate and hoisted the first British flag on the Değirmen Bastion next to the Paphos Gate . Nicosia Municipality was established in 1882. Under British rule, Nicosia grew outside the city walls. Between 1930 and 1945, villages such as Ortaköy , Strovolos , Büyük Kaymaklı , Küçük Kaymaklı began to merge with the city, and the first settlements were made in regions such as Yenişehir . On January 1, 1944, Ayii Omoloyitadhes was included in the municipal boundaries. In order to provide access outside the city, the walls on the sides of the Paphos Gate in 1879, the Kyrenia Gate in 1931, and the Famagusta Gate in 1945 were cut. In 1905, a train station was built in Büyük Kaymaklı and train services to Nicosia started, this practice ended in 1955. In 1912, the first electricity came to the city. Also in the same year, kerosene-powered street lamps were replaced with electric ones. Under British rule, the sewer network was cleaned and the roads were repaired. On October 17, 1947, as a result of an explosion in the power plant that supplied energy to the city, the city was left without electricity for 116 days.
In 1895, Greeks attacked the Turks in the Tahtakale region of Nicosia. In 1931, Greeks rebelled against British rule and burned the government building. Founded in 1955, EOKA attacked public buildings and the radio station in the city against British rule.
The Republic of Cyprus was established on 16 August 1960 . The flag of the Republic of Cyprus was hoisted in the House of Representatives at midnight that night, ending British rule on the island. In accordance with Article 173 of the 1960 constitution, a Greek (Nicosia -Greek Municipality) and a Turkish ( Nicosia Turkish Municipality ) municipality were established on the island. On the night of 20–21 December 1963, the events known as " Bloody Christmas " began. Zeki Halil and Cemaliye Emirali were killed as a result of fire opened on cars in Tahtakale district of Nicosia. Between 23-30, Küçük Kaymaklı was besieged. On the night of 23-24 January, 11 people were killed in the Kumsal region, and the family of Turkish major Nihat İlhan was killed in the incident known as the Kumsal Raid. An attack was carried out against the Turks in the Kanlıdere region. As a result of the events, the governments of Turkey , Greece and the United Kingdom met on 30 December 1963 . As a result of this meeting, the border , also known as the Green Line, was drawn, dividing the city into Turkish and Greek parts. The reason why this border is called the "Green Line" is that the pen of the United Nations official who drew the line on the map was green. The borders of the city were finalized with the Cyprus Operation carried out in 1974 by the order of Turkish Prime Minister Bülent Ecevit .
On 29 March 1968, the suburbs of Eylence , Büyük Kaymaklı, Küçük Kaymaklı, Pallouriotissa , Strovolos (partially) and Kızılay were also included in the municipal borders. Following the de facto division of the city, the area under the administration of the Republic of Cyprus continued to grow in a southerly direction. North Nicosia also continued to grow and merged with outlying villages such as Gönyeli (which has a separate municipality) and Hamitköy (which is part of the Nicosia Turkish Municipality).
Kermiya Border Gate was opened in 2003, and Lokmacı Gate was opened in 2008 .
Nicosia is located in a central point of the island of Cyprus, in the central parts of the Mesarya Plain .
Nicosia has a hot semi-arid climate according to the Köppen climate classification . The hottest months are July and August, and the coldest months are January and February. The month with the most rainfall is January. Nicosia is one of the warmest places on the island.
Nicosia is located in the center of the geological formation called Nicosia Formation. This region dates back to the Lower Pliocene period. Gray, yellow and white marl layers, sandy and yellow limestones and sparse conglomerate bands are frequently encountered. The reconnection of the Mediterranean with the Atlantic Ocean resulted in the rise of sea water and the formation of new sediments, which formed the Nicosia Formation. Underneath Nicosia is the Nicosia- Serdarlı aquifer , which has an area of 60 km² .
The riverside parts of Nicosia city, especially Kanlıdere , have a great biodiversity. [88] In a research conducted in the streams in a 12.5 km diameter area of the city, which is rich in vegetation (especially in stream beds), 185 different plant species belonging to 62 different families were identified. Among these, there are four endemic and 16 rare species. The most common tree species found on the banks of streams in the city is the eucalyptus tree (various types can be found). There is a total of 0.262 square kilometers of forest area in the Nicosia Central agricultural region of Northern Cyprus . Two kilometers outside Nicosia (in its southern part), within the boundaries of the Municipality of Eylence, is the Pedagogical Academy National Forest Park, and to the south of the city is the Athalassa National Forest Park. In Northern Nicosia, there is the Nicosia Forest Nursery, which is 0.5 hectares in size.
The habitats of animals in the stream beds in some parts of the city are in danger. The reeds along the streams host many animals, especially bird species. Many creatures such as kingfishers , water chickens , striped turtles and chameleons live on the banks of the streams . There are especially many turtles in the streams.
Nicosia is the commercial center of Cyprus. The city hosts the central banks of the Republic of Cyprus and the Turkish Republic of Northern Cyprus .
The city of Nicosia is divided into two parts in terms of urbanization, these are old Nicosia (the area inside the walls) and new Nicosia (outside the walls). In Old Nicosia, the roads are narrow and there are dead ends. In New Nicosia, there is more vertical and horizontal development over a wider area. Junctions and roads are wider, parks occupy larger areas.
In Nicosia during the Ottoman period, Greeks and Turks lived mixed in some neighborhoods, and in some neighborhoods, one of them was the majority. Mosques can be found in Turkish neighborhoods and churches in Greek neighborhoods. Armenians also lived in the city. The houses of the Armenians who used to live in Köşklüçiftlik were all made of cut stone and had their own unique architecture. Bay windows are a common feature in houses in Old Nicosia . The Büyük Han is one of the most advanced architectural works on the island, and today it is a cultural center where various activities such as exhibitions, sales of antiques and traditional items, and shadow plays take place.
There are fourteen museums in the part of Nicosia south of the Green Line. The Cyprus Museum was founded in 1888 and exhibits hundreds of archaeological artifacts brought from all over the island. The house of Hadjigeorgakis Kornesios, who worked as a translator for the Divan during the Ottoman period, built in 1793, is used as an ethnography museum. In the northern part of the city, the number of museums is six. Derviş Pasha Mansion is used as an ethnography museum.
Although there are many theaters in the south of the city, the headquarters of the Cyprus Theater Association is in Nicosia. The State Theater Building, built in the 2000s, formerly hosted this institution, which suffered from inadequate facilities, and is not allowed to be used by any other theater organization. Nicosia Municipality Theatre, built in 1967, has a capacity of 1220 people. In the north, the Turkish Cypriot State Theater performs plays and organizes tours; but it does not have a hall. Also in the north is the Nicosia Municipal Theater, which was established in 1980. The Cyprus Theater Festival, jointly organized by the Nicosia Turkish Municipality and Nicosia Municipal Theatres, is a large organization attended by institutions such as Istanbul City Theatres , and all of these can be held in only two halls.
There are nineteen cinemas in the southern part of the city, six of which are owned by a company called K Cineplex, and thirteen are owned by other companies. In the north of the city, the number of cinemas is four.
Two waterways built during the Ottoman period were used in Nicosia until the mid-20th century. These waterways were Arab Ahmed and Silihtar waterways. Apart from this, water extracted from wells was also used.
Telegraph was first used in the city in 1873. In 1936, a public telephone network was established covering the entire island and Nicosia.
The migration to the city of Nicosia as a result of the Cyprus Operation in 1974 caused problems such as development, transportation, sewerage, housing shortage and lack of infrastructure in the city.
Since Nicosia is a divided city, the Republic of Cyprus and Northern Cyprus education systems are implemented in the city. A university called Near East University in North Nicosia , Cyprus International University, Mediterranean Karpaz University, Anadolu University 's open education faculty, apart from these, colleges such as Atatürk Teachers Academy and Police School There are. In the area under the control of the Republic of Cyprus , there are universities named University of Cyprus , Open University of Cyprus , Frederick University , University of Nicosia , [132] and European University of Cyprus.
In the Nicosia District of the Republic of Cyprus, there are 42 secondary schools, 133 primary schools and three kindergartens. There are a total of 30 primary schools, kindergartens and special education centers at the primary level in the Nicosia district of Northern Cyprus .
The roads on the island were built to be centered in Nicosia and unite in Nicosia. All important roads meet in Nicosia. During the Ottoman period, only the Larnaca road was built, and the previously built roads were in ruins. Under British rule, these roads were rebuilt and a regular postal service was established between Nicosia and other cities. The first car arrived in the city in 1907. The first bus services from the city started in 1929, these services departed from the Kyrenia Gate and went to Strovolos, Aydemet and Büyük Kaymaklı. [139] Train services started between Nicosia and Famagusta on 21 October 1905 . Train services were organized from Nicosia to approximately 30 stops. Train services ended on December 31, 1951. Nicosia International Airport was opened in 1949 . This airport is in the Buffer Zone today and is not used.
Today, there is a bus service in the Republic of Cyprus controlled part of the city run by a company called Nicosia Bus Company . All buses leave from the terminal in Solomos Square and make stops every 20 to 30 minutes. There are plans to expand the bus line, increase the frequency of services and renew the bus fleet. The Department of Public Works signed an agreement to establish tram and light rail lines between Nicosia - Larnaca and Limassol . There are motorways such as A1 and A2 from the city . In addition to developing this road network, there are also projects to improve the roads within the city. Apart from this, there are also taxis . Air transportation to the city is provided by Larnaca International Airport (44 km away) and Paphos International Airport . Larnaca Airport is used more than Paphos Airport.
LETTAŞ company also has buses in North Nicosia. The first municipal bus was put into operation on the Göçmenköy-Yenişehir route on January 15, 1980, during Mustafa Akıncı 's term as mayor. Starting from 1984, this service was transformed into a public transportation network within the municipality and started to provide service, and later the same vehicles were privatized to be operated by the LETTAŞ company. There is a bus terminal in the Yenişehir area. The airport used by the northern part of the city is Ercan Airport . Transportation to the airport is provided by buses. It is also possible to reach the city by taxi and minibus .

Northern Cyprus, officially the Turkish Republic of Northern Cyprus (TRNC), is a de facto state that comprises the northeastern portion of the island of Cyprus. It is recognised only by Turkey, and its territory is considered by all other states to be part of the Republic of Cyprus.
Northern Cyprus extends from the tip of the Karpass Peninsula in the northeast to Morphou Bay, Cape Kormakitis and its westernmost point, the Kokkina exclave in the west. Its southernmost point is the village of Louroujina. A buffer zone under the control of the United Nations stretches between Northern Cyprus and the rest of the island and divides Nicosia, the island's largest city and capital of both sides.
A coup d'état in 1974, performed as part of an attempt to annex the island to Greece, prompted the Turkish invasion of Cyprus. This resulted in the eviction of much of the north's Greek Cypriot population, the flight of Turkish Cypriots from the south, and the partitioning of the island, leading to a unilateral declaration of independence by the north in 1983. Due to its lack of recognition, Northern Cyprus is heavily dependent on Turkey for economic, political and military support.
Attempts to reach a solution to the Cyprus dispute have been unsuccessful. The Turkish Army maintains a large force in Northern Cyprus with the support and approval of the TRNC government, while the Republic of Cyprus, the European Union as a whole, and the international community regard it as an occupation force. This military presence has been denounced in several United Nations Security Council resolutions.
Northern Cyprus is a semi-presidential, democratic republic with a cultural heritage incorporating various influences and an economy that is dominated by the services sector. The economy has seen growth through the 2000s and 2010s, with the GNP per capita more than tripling in the 2000s, but is held back by an international embargo due to the official closure of the ports in Northern Cyprus by the Republic of Cyprus. The official language is Turkish, with a distinct local dialect being spoken. The vast majority of the population consists of Sunni Muslims, while religious attitudes are mostly moderate and secular. Northern Cyprus is an observer state of ECO and OIC under the name "Turkish Cypriot State", PACE under the name "Turkish Cypriot Community", and Organization of Turkic States with its own name.
Several distinct periods of Cypriot intercommunal violence involving the two main ethnic communities, Greek Cypriots and Turkish Cypriots, marked mid-20th century Cyprus. These included the Cyprus Emergency of 1955–59 during British rule, the post-independence Cyprus crisis of 1963–64, and the Cyprus crisis of 1967. Hostilities culminated in the 1974 de facto division of the island along the Green Line following the Turkish invasion of Cyprus. The region has been relatively peaceful since then, but the Cyprus dispute has continued, with various attempts to solve it diplomatically having been generally unsuccessful.
Cyprus, an island lying in the eastern Mediterranean, hosted a population of Greeks and Turks (four-fifths and one-fifth, respectively), who lived under British rule in the late nineteenth-century and the first half of the twentieth-century. Christian Orthodox Church of Cyprus played a prominent political role among the Greek Cypriot community, a privilege that it acquired during the Ottoman Empire with the employment of the millet system, which gave the archbishop an unofficial ethnarch status.
The repeated rejections by the British of Greek Cypriot demands for enosis, union with Greece, led to armed resistance, organised by the National Organization of Cypriot Struggle, or EOKA. EOKA, led by the Greek-Cypriot commander George Grivas, systematically targeted British colonial authorities. One of the effects of EOKA's campaign was to alter the Turkish position from demanding full reincorporation into Turkey to a demand for taksim (partition). EOKA's mission and activities caused a "Cretan syndrome" (see Turkish Resistance Organisation) within the Turkish Cypriot community, as its members feared that they would be forced to leave the island in such a case as had been the case with Cretan Turks. As such, they preferred the continuation of British colonial rule and then taksim, the division of the island. Due to the Turkish Cypriots' support for the British, EOKA's leader, Georgios Grivas, declared them to be enemies. The fact that the Turks were a minority was, according to Nihat Erim, to be addressed by the transfer of thousands of Turks from mainland Turkey so that Greek Cypriots would cease to be the majority. When Erim visited Cyprus as the Turkish representative, he was advised by Field Marshal Sir John Harding, the then Governor of Cyprus, that Turkey should send educated Turks to settle in Cyprus.
Turkey actively promoted the idea that on the island of Cyprus two distinctive communities existed, and sidestepped its former claim that "the people of Cyprus were all Turkish subjects". In doing so, Turkey's aim to have self-determination of two to-be equal communities in effect led to de jure partition of the island.[citation needed] This could be justified to the international community against the will of the majority Greek population of the island. Dr. Fazil Küçük in 1954 had already proposed Cyprus be divided in two at the 35° parallel.
Lindley Dan, from Notre Dame University, spotted the roots of intercommunal violence to different visions among the two communities of Cyprus (enosis for Greek Cypriots, taksim for Turkish Cypriots). Also, Lindlay wrote that "the merging of church, schools/education, and politics in divisive and nationalistic ways" had played a crucial role in creation of havoc in Cyprus' history. Attalides Michael also pointed to the opposing nationalisms as the cause of the Cyprus problem.
By the mid-1950's, the "Cyprus is Turkish" party, movement, and slogan gained force in both Cyprus and Turkey. In a 1954 editorial, Turkish Cypriot leader Dr. Fazil Kuchuk expressed the sentiment that the Turkish youth had grown up with the idea that "as soon as Great Britain leaves the island, it will be taken over by the Turks", and that "Turkey cannot tolerate otherwise". This perspective contributed to the willingness of Turkish Cypriots to align themselves with the British, who started recruiting Turkish Cypriots into the police force that patrolled Cyprus to fight EOKA, a Greek Cypriot nationalist organisation that sought to rid the island of British rule.
EOKA targeted colonial authorities, including police, but Georgios Grivas, the leader of EOKA, did not initially wish to open up a new front by fighting Turkish Cypriots and reassured them that EOKA would not harm their people. In 1956, some Turkish Cypriot policemen were killed by EOKA members and this provoked some intercommunal violence in the spring and summer, but these attacks on policemen were not motivated by the fact that they were Turkish Cypriots.
However, in January 1957, Grivas changed his policy as his forces in the mountains became increasingly pressured by the British Crown forces. In order to divert the attention of the Crown forces, EOKA members started to target Turkish Cypriot policemen intentionally in the towns, so that Turkish Cypriots would riot against the Greek Cypriots and the security forces would have to be diverted to the towns to restore order. The killing of a Turkish Cypriot policeman on 19 January, when a power station was bombed, and the injury of three others, provoked three days of intercommunal violence in Nicosia. The two communities targeted each other in reprisals, at least one Greek Cypriot was killed and the British Army was deployed in the streets. Greek Cypriot stores were burned and their neighbourhoods attacked. Following the events, the Greek Cypriot leadership spread the propaganda that the riots had merely been an act of Turkish Cypriot aggression. Such events created chaos and drove the communities apart both in Cyprus and in Turkey.
On 22 October 1957 Sir Hugh Mackintosh Foot replaced Sir John Harding as the British Governor of Cyprus. Foot suggested five to seven years of self-government before any final decision. His plan rejected both enosis and taksim. The Turkish Cypriot response to this plan was a series of anti-British demonstrations in Nicosia on 27 and 28 January 1958 rejecting the proposed plan because the plan did not include partition. The British then withdrew the plan.
In 1957, Black Gang, a Turkish Cypriot pro-taksim paramilitary organisation, was formed to patrol a Turkish Cypriot enclave, the Tahtakale district of Nicosia, against activities of EOKA. The organisation later attempted to grow into a national scale, but failed to gain public support.
By 1958, signs of dissatisfaction with the British increased on both sides, with a group of Turkish Cypriots forming Volkan (later renamed to the Turkish Resistance Organisation) paramilitary group to promote partition and the annexation of Cyprus to Turkey as dictated by the Menderes plan. Volkan initially consisted of roughly 100 members, with the stated aim of raising awareness in Turkey of the Cyprus issue and courting military training and support for Turkish Cypriot fighters from the Turkish government.
In June 1958, the British Prime Minister, Harold Macmillan, was expected to propose a plan to resolve the Cyprus issue. In light of the new development, the Turks rioted in Nicosia to promote the idea that Greek and Turkish Cypriots could not live together and therefore any plan that did not include partition would not be viable. This violence was soon followed by bombing, Greek Cypriot deaths and looting of Greek Cypriot-owned shops and houses. Greek and Turkish Cypriots started to flee mixed population villages where they were a minority in search of safety. This was effectively the beginning of the segregation of the two communities. On 7 June 1958, a bomb exploded at the entrance of the Turkish Embassy in Cyprus. Following the bombing, Turkish Cypriots looted Greek Cypriot properties. On 26 June 1984, the Turkish Cypriot leader, Rauf Denktaş, admitted on British channel ITV that the bomb was placed by the Turks themselves in order to create tension. On 9 January 1995, Rauf Denktaş repeated his claim to the famous Turkish newspaper Milliyet in Turkey.
The crisis reached a climax on 12 June 1958, when eight Greeks, out of an armed group of thirty five arrested by soldiers of the Royal Horse Guards on suspicion of preparing an attack on the Turkish quarter of Skylloura, were killed in a suspected attack by Turkish Cypriot locals, near the village of Geunyeli, having been ordered to walk back to their village of Kondemenos.
After the EOKA campaign had begun, the British government successfully began to turn the Cyprus issue from a British colonial problem into a Greek-Turkish issue. British diplomacy exerted backstage influence on the Adnan Menderes government, with the aim of making Turkey active in Cyprus. For the British, the attempt had a twofold objective. The EOKA campaign would be silenced as quickly as possible, and Turkish Cypriots would not side with Greek Cypriots against the British colonial claims over the island, which would thus remain under the British. The Turkish Cypriot leadership visited Menderes to discuss the Cyprus issue. When asked how the Turkish Cypriots should respond to the Greek Cypriot claim of enosis, Menderes replied: "You should go to the British foreign minister and request the status quo be prolonged, Cyprus to remain as a British colony". When the Turkish Cypriots visited the British Foreign Secretary and requested for Cyprus to remain a colony, he replied: "You should not be asking for colonialism at this day and age, you should be asking for Cyprus be returned to Turkey, its former owner".
As Turkish Cypriots began to look to Turkey for protection, Greek Cypriots soon understood that enosis was extremely unlikely. The Greek Cypriot leader, Archbishop Makarios III, now set independence for the island as his objective.
Britain resolved to solve the dispute by creating an independent Cyprus. In 1959, all involved parties signed the Zurich Agreements: Britain, Turkey, Greece, and the Greek and Turkish Cypriot leaders, Makarios and Dr. Fazil Kucuk, respectively. The new constitution drew heavily on the ethnic composition of the island. The President would be a Greek Cypriot, and the Vice-President a Turkish Cypriot with an equal veto. The contribution to the public service would be set at a ratio of 70:30, and the Supreme Court would consist of an equal number of judges from both communities as well as an independent judge who was not Greek, Turkish or British. The Zurich Agreements were supplemented by a number of treaties. The Treaty of Guarantee stated that secession or union with any state was forbidden, and that Greece, Turkey and Britain would be given guarantor status to intervene if that was violated. The Treaty of Alliance allowed for two small Greek and Turkish military contingents to be stationed on the island, and the Treaty of Establishment gave Britain sovereignty over two bases in Akrotiri and Dhekelia.
On 15 August 1960, the Colony of Cyprus became fully independent as the Republic of Cyprus. The new republic remained within the Commonwealth of Nations.
The new constitution brought dissatisfaction to Greek Cypriots, who felt it to be highly unjust for them for historical, demographic and contributional reasons. Although 80% of the island's population were Greek Cypriots and these indigenous people had lived on the island for thousands of years and paid 94% of taxes, the new constitution was giving the 17% of the population that was Turkish Cypriots, who paid 6% of taxes, around 30% of government jobs and 40% of national security jobs.
Within three years tensions between the two communities in administrative affairs began to show. In particular disputes over separate municipalities and taxation created a deadlock in government. A constitutional court ruled in 1963 Makarios had failed to uphold article 173 of the constitution which called for the establishment of separate municipalities for Turkish Cypriots. Makarios subsequently declared his intention to ignore the judgement, resulting in the West German judge resigning from his position. Makarios proposed thirteen amendments to the constitution, which would have had the effect of resolving most of the issues in the Greek Cypriot favour. Under the proposals, the President and Vice-President would lose their veto, the separate municipalities as sought after by the Turkish Cypriots would be abandoned, the need for separate majorities by both communities in passing legislation would be discarded and the civil service contribution would be set at actual population ratios (82:18) instead of the slightly higher figure for Turkish Cypriots.
The intention behind the amendments has long been called into question. The Akritas plan, written in the height of the constitutional dispute by the Greek Cypriot interior minister Polycarpos Georkadjis, called for the removal of undesirable elements of the constitution so as to allow power-sharing to work. The plan envisaged a swift retaliatory attack on Turkish Cypriot strongholds should Turkish Cypriots resort to violence to resist the measures, stating "In the event of a planned or staged Turkish attack, it is imperative to overcome it by force in the shortest possible time, because if we succeed in gaining command of the situation (in one or two days), no outside, intervention would be either justified or possible." Whether Makarios's proposals were part of the Akritas plan is unclear, however it remains that sentiment towards enosis had not completely disappeared with independence. Makarios described independence as "a step on the road to enosis".[31] Preparations for conflict were not entirely absent from Turkish Cypriots either, with right wing elements still believing taksim (partition) the best safeguard against enosis.
Greek Cypriots however believe the amendments were a necessity stemming from a perceived attempt by Turkish Cypriots to frustrate the working of government. Turkish Cypriots saw it as a means to reduce their status within the state from one of co-founder to that of minority, seeing it as a first step towards enosis. The security situation deteriorated rapidly.
Main articles: Bloody Christmas (1963) and Battle of Tillyria
An armed conflict was triggered after December 21, 1963, a period remembered by Turkish Cypriots as Bloody Christmas, when a Greek Cypriot policemen that had been called to help deal with a taxi driver refusing officers already on the scene access to check the identification documents of his customers, took out his gun upon arrival and shot and killed the taxi driver and his partner. Eric Solsten summarised the events as follows: "a Greek Cypriot police patrol, ostensibly checking identification documents, stopped a Turkish Cypriot couple on the edge of the Turkish quarter. A hostile crowd gathered, shots were fired, and two Turkish Cypriots were killed."
In the morning after the shooting, crowds gathered in protest in Northern Nicosia, likely encouraged by the TMT, without incident. On the evening of the 22nd, gunfire broke out, communication lines to the Turkish neighbourhoods were cut, and the Greek Cypriot police occupied the nearby airport. On the 23rd, a ceasefire was negotiated, but did not hold. Fighting, including automatic weapons fire, between Greek and Turkish Cypriots and militias increased in Nicosia and Larnaca. A force of Greek Cypriot irregulars led by Nikos Sampson entered the Nicosia suburb of Omorphita and engaged in heavy firing on armed, as well as by some accounts unarmed, Turkish Cypriots. The Omorphita clash has been described by Turkish Cypriots as a massacre, while this view has generally not been acknowledged by Greek Cypriots.
Further ceasefires were arranged between the two sides, but also failed. By Christmas Eve, the 24th, Britain, Greece, and Turkey had joined talks, with all sides calling for a truce. On Christmas day, Turkish fighter jets overflew Nicosia in a show of support. Finally it was agreed to allow a force of 2,700 British soldiers to help enforce a ceasefire. In the next days, a "buffer zone" was created in Nicosia, and a British officer marked a line on a map with green ink, separating the two sides of the city, which was the beginning of the "Green Line". Fighting continued across the island for the next several weeks.
In total 364 Turkish Cypriots and 174 Greek Cypriots were killed during the violence. 25,000 Turkish Cypriots from 103-109 villages fled and were displaced into enclaves and thousands of Turkish Cypriot houses were ransacked or completely destroyed.
Contemporary newspapers also reported on the forceful exodus of the Turkish Cypriots from their homes. According to The Times in 1964, threats, shootings and attempts of arson were committed against the Turkish Cypriots to force them out of their homes. The Daily Express wrote that "25,000 Turks have already been forced to leave their homes". The Guardian reported a massacre of Turks at Limassol on 16 February 1964.
Turkey had by now readied its fleet and its fighter jets appeared over Nicosia. Turkey was dissuaded from direct involvement by the creation of a United Nations Peacekeeping Force in Cyprus (UNFICYP) in 1964. Despite the negotiated ceasefire in Nicosia, attacks on the Turkish Cypriot persisted, particularly in Limassol. Concerned about the possibility of a Turkish invasion, Makarios undertook the creation of a Greek Cypriot conscript-based army called the "National Guard". A general from Greece took charge of the army, whilst a further 20,000 well-equipped officers and men were smuggled from Greece into Cyprus. Turkey threatened to intervene once more, but was prevented by a strongly worded letter from the American President Lyndon B. Johnson, anxious to avoid a conflict between NATO allies Greece and Turkey at the height of the Cold War.
Turkish Cypriots had by now established an important bridgehead at Kokkina, provided with arms, volunteers and materials from Turkey and abroad. Seeing this incursion of foreign weapons and troops as a major threat, the Cypriot government invited George Grivas to return from Greece as commander of the Greek troops on the island and launch a major attack on the bridgehead. Turkey retaliated by dispatching its fighter jets to bomb Greek positions, causing Makarios to threaten an attack on every Turkish Cypriot village on the island if the bombings did not cease. The conflict had now drawn in Greece and Turkey, with both countries amassing troops on their Thracian borders. Efforts at mediation by Dean Acheson, a former U.S. Secretary of State, and UN-appointed mediator Galo Plaza had failed, all the while the division of the two communities becoming more apparent. Greek Cypriot forces were estimated at some 30,000, including the National Guard and the large contingent from Greece. Defending the Turkish Cypriot enclaves was a force of approximately 5,000 irregulars, led by a Turkish colonel, but lacking the equipment and organisation of the Greek forces.
The Secretary-General of the United Nations in 1964, U Thant, reported the damage during the conflicts:
UNFICYP carried out a detailed survey of all damage to properties throughout the island during the disturbances; it shows that in 109 villages, most of them Turkish-Cypriot or mixed villages, 527 houses have been destroyed while 2,000 others have suffered damage from looting.
The situation worsened in 1967, when a military junta overthrew the democratically elected government of Greece, and began applying pressure on Makarios to achieve enosis. Makarios, not wishing to become part of a military dictatorship or trigger a Turkish invasion, began to distance himself from the goal of enosis. This caused tensions with the junta in Greece as well as George Grivas in Cyprus. Grivas's control over the National Guard and Greek contingent was seen as a threat to Makarios's position, who now feared a possible coup.[citation needed] The National Guard and Cyprus Police began patrolling the Turkish Cypriot enclaves of Ayios Theodoros and Kophinou, and on November 15 engaged in heavy fighting with the Turkish Cypriots.
By the time of his withdrawal 26 Turkish Cypriots had been killed. Turkey replied with an ultimatum demanding that Grivas be removed from the island, that the troops smuggled from Greece in excess of the limits of the Treaty of Alliance be removed, and that the economic blockades on the Turkish Cypriot enclaves be lifted. Grivas was recalled by the Athens Junta and the 12,000 Greek troops were withdrawn. Makarios now attempted to consolidate his position by reducing the number of National Guard troops, and by creating a paramilitary force loyal to Cypriot independence. In 1968, acknowledging that enosis was now all but impossible, Makarios stated, "A solution by necessity must be sought within the limits of what is feasible which does not always coincide with the limits of what is desirable."
After 1967 tensions between the Greek and Turkish Cypriots subsided. Instead, the main source of tension on the island came from factions within the Greek Cypriot community. Although Makarios had effectively abandoned enosis in favour of an 'attainable solution', many others continued to believe that the only legitimate political aspiration for Greek Cypriots was union with Greece.
On his arrival, Grivas began by establishing a nationalist paramilitary group known as the National Organization of Cypriot Fighters (Ethniki Organosis Kyprion Agoniston B or EOKA-B), drawing comparisons with the EOKA struggle for enosis under the British colonial administration of the 1950s.
The military junta in Athens saw Makarios as an obstacle. Makarios's failure to disband the National Guard, whose officer class was dominated by mainland Greeks, had meant the junta had practical control over the Cypriot military establishment, leaving Makarios isolated and a vulnerable target.
During the first Turkish invasion, Turkish troops invaded Cyprus territory on 20 July 1974, invoking its rights under the Treaty of Guarantee. This expansion of Turkish-occupied zone violated International Law as well as the Charter of the United Nations. Turkish troops managed to capture 3% of the island which was accompanied by the burning of the Turkish Cypriot quarter, as well as the raping and killing of women and children. A temporary cease-fire followed which was mitigated by the UN Security Council. Subsequently, the Greek military Junta collapsed on July 23, 1974, and peace talks commenced in which a democratic government was installed. The Resolution 353 was broken after Turkey attacked a second time and managed to get a hold of 37% of Cyprus territory. The Island of Cyprus was appointed a Buffer Zone by the United Nations, which divided the island into two zones through the 'Green Line' and put an end to the Turkish invasion. Although Turkey announced that the occupied areas of Cyprus to be called the Federated Turkish State in 1975, it is not legitimised on a worldwide political scale. The United Nations called for the international recognition of independence for the Republic of Cyprus in the Security Council Resolution 367.
In the years after the Turkish invasion of northern Cyprus one can observe a history of failed talks between the two parties. The 1983 declaration of the independent Turkish Republic of Cyprus resulted in a rise of inter-communal tensions and made it increasingly hard to find mutual understanding. With Cyprus' interest of a possible EU membership and a new UN Secretary-General Kofi Annan in 1997 new hopes arose for a fresh start. International involvement from sides of the US and UK, wanting a solution to the Cyprus dispute prior to the EU accession led to political pressures for new talks. The believe that an accession without a solution would threaten Greek-Turkish relations and acknowledge the partition of the island would direct the coming negotiations.
Over the course of two years a concrete plan, the Annan plan was formulated. In 2004 the fifth version agreed upon from both sides and with the endorsement of Turkey, US, UK and EU then was presented to the public and was given a referendum in both Cypriot communities to assure the legitimisation of the resolution. The Turkish Cypriots voted with 65% for the plan, however the Greek Cypriots voted with a 76% majority against. The Annan plan contained multiple important topics. Firstly it established a confederation of two separate states called the United Cyprus Republic. Both communities would have autonomous states combined under one unified government. The members of parliament would be chosen according to the percentage in population numbers to ensure a just involvement from both communities. The paper proposed a demilitarisation of the island over the next years. Furthermore it agreed upon a number of 45000 Turkish settlers that could remain on the island. These settlers became a very important issue concerning peace talks. Originally the Turkish government encouraged Turks to settle in Cyprus providing transfer and property, to establish a counterpart to the Greek Cypriot population due to their 1 to 5 minority. With the economic situation many Turkish-Cypriot decided to leave the island, however their departure is made up by incoming Turkish settlers leaving the population ratio between Turkish Cypriots and Greek Cypriots stable. However all these points where criticised and as seen in the vote rejected mainly by the Greek Cypriots. These name the dissolution of the „Republic of Cyprus", economic consequences of a reunion and the remaining Turkish settlers as reason. Many claim that the plan was indeed drawing more from Turkish-Cypriot demands then Greek-Cypriot interests. Taking in consideration that the US wanted to keep Turkey as a strategic partner in future Middle Eastern conflicts.
A week after the failed referendum the Republic of Cyprus joined the EU. In multiple instances the EU tried to promote trade with Northern Cyprus but without internationally recognised ports this spiked a grand debate. Both side endure their intention of negotiations, however without the prospect of any new compromises or agreements the UN is unwilling to start the process again. Since 2004 negotiations took place in numbers but without any results, both sides are strongly holding on to their position without an agreeable solution in sight that would suit both parties.
March 25, 2013 -- Line number 86, a Boeing-owned 787 airplane built for LOT Polish Airlines, departs Paine Field in Everett, Wash. for a functional check flight. The airplane took off at 12:11 pm Pacific Time.
The flight is a normal Boeing production check flight intended to validate that all systems function as designed. During a functional check flight, crews cycle the landing gear and operate all the backup systems, in addition to performing electrical system checks from the flight profile. Across airplane programs, more than 600 functional check flights were completed in 2012.
Following the completion of the functional check flight, we will analyze the data from the flight and prepare for certification ground and flight demonstration in the coming days. The plan is to conduct one certification demonstration flight. That flight, which will take plan on Line 86, will demonstrate that the new battery system performs as intended during flight conditions.
Bacha log, in this Module we are going to see different, different Marketing Strategic
Techniques. To start with Social Marketing, now it aims to increase the acceptability of a
social idea, cause or practice among a target group. Example is campaign for prohibition of
smoking, right. Second example would be P&G, they collect or they donate, right, for every
product that we buy out of which 2 or 3 rupees is donated towards Girl Child Shiksha
Abhiyan. Isn’t it good, yes?
Next we see is Augmented Marketing, now in here it is the provision of additional customer
services and benefit built around the core and the actual products that relate to the
introduction of hi-tech services like, online computer services, etc. Herein example could be
Asian Paints, they give five years warranty on certain paints.
Direct Marketing, is a marketing strategy that interacts directly with the consumers asking
them to make a direct response. Example through catalogues selling, mail, electronic
marketing, Television shopping, etc.
Relationship Marketing, it is a process of creating, maintaining and enhancing strong value
laden relationships with customers and other stakeholders. It will go a long way in building
relationships. Example, Emirates, right, when you fly by Emirates they send a Mercedes,
right, per passenger at your residence, so if it is a family of four, you can even ask for four
Mercedes and they provide. And they pick you up from your door, that is your home till
airport. And again from your destination airport to the hotel a Mercedes service is
provided. Same, British Airways, offers special lounges with showers at 199 airports for
frequent fliers. Isn’t it amazing, yes.
Next, Services Marketing, It is applying the concepts, tools and techniques of marketing to
services. Services is any activity that one party can offer to another that is essentially

Model "US Truck T1 MkII" is build with LEGO® in scale 1:17,5 and motorized using LEGO® Power Functions. It is not build after a specific brand or type of truck. This build represents the more aerodynamic US truck models like for example the Freightliner Cascadia.
The truck features: solid axle suspension on all axles, PF powered driving with power transmitted independently to both rear axles, Ackerman geometry on steering axle, Servo powered steering, fully functional fifth wheel, modeled engine, detailed cabin interior and 3 light units.
Also can you build it yourself. To do so you can buy the building instructions and check the inventory/parts lists!.
The LEGO® Power Functions® Servo is used to enable the steering. Aligned with the trucks chassis the Servo is sitting inside of the cabin right behind the modeled engine in between both seats. With a 90 degrees conversion the motion of the Servo is transferred to the steering axle.
This truck model is powered by a CAT® CT15 which is revealed with the hood opened and its yellow color makes is an eye catcher. This power source is an inline 6 cylinder engine with a displacement of 15.21L. With a horsepower range from 450 up to 550 HP and this engine has a torque range from 1550 to 1850 lb-ft. (1202 - 2508 Nm) at 1200 rpm peak torque.
The modeled engine is a small object that really improves the realism of this model. The engine is very nice to build and to give it those realistic looks a total number of about 120 parts is used. Engine is detailed with for example engine oil dipstick, fan, fan belt, pulleys, hoses, oil filters including by-pass oil filter, turbo, exhaust manifold and so on. Together with much more engine bay details which are added the looks are phenomenal. These include break fluid reservoir, windshield washer container, internal air cleaner system and steering shaft.
A lot of detail is added to the cabin's interior as well in the colors Tan and Dark Bluish Gray. By opening this model’s doors one can access the cabin. Openable doors give the model very realistic looks and makes the detailed interior visible. The interior's colors really standout because of the rather dark color scheme of the truck's body work.
Dark Bluish Gray is used for both the interior and the exterior in order to link both color palettes. For the driver's comfort the interior has gauges, switches, speakers, cup holders, comfortable seats. Other details are a glove compartment, more compartments in both doors, angled dash and gauge panel, a steering wheel and a gear shift.
Fish, any of approximately 34,000 species of vertebrate animals (phylum Chordata) found in the fresh and salt waters of the world. Living species range from the primitive jawless lampreys and hagfishes through the cartilaginous sharks, skates, and rays to the abundant and diverse bony fishes. Most fish species are cold-blooded; however, one species, the opah (Lampris guttatus), is warm-blooded.
The term fish is applied to a variety of vertebrates of several evolutionary lines. It describes a life-form rather than a taxonomic group. As members of the phylum Chordata, fish share certain features with other vertebrates. These features are gill slits at some point in the life cycle, a notochord, or skeletal supporting rod, a dorsal hollow nerve cord, and a tail. Living fishes represent some five classes, which are as distinct from one another as are the four classes of familiar air-breathing animals—amphibians, reptiles, birds, and mammals. For example, the jawless fishes (Agnatha) have gills in pouches and lack limb girdles. Extant agnathans are the lampreys and the hagfishes. As the name implies, the skeletons of fishes of the class Chondrichthyes (from chondr, “cartilage,” and ichthyes, “fish”) are made entirely of cartilage. Modern fish of this class lack a swim bladder, and their scales and teeth are made up of the same placoid material. Sharks, skates, and rays are examples of cartilaginous fishes. The bony fishes are by far the largest class. Examples range from the tiny seahorse to the 450-kg (1,000-pound) blue marlin, from the flattened soles and flounders to the boxy puffers and ocean sunfishes. Unlike the scales of the cartilaginous fishes, those of bony fishes, when present, grow throughout life and are made up of thin overlapping plates of bone. Bony fishes also have an operculum that covers the gill slits.
The study of fishes, the science of ichthyology, is of broad importance. Fishes are of interest to humans for many reasons, the most important being their relationship with and dependence on the environment. A more obvious reason for interest in fishes is their role as a moderate but important part of the world’s food supply. This resource, once thought unlimited, is now realized to be finite and in delicate balance with the biological, chemical, and physical factors of the aquatic environment. Overfishing, pollution, and alteration of the environment are the chief enemies of proper fisheries management, both in fresh waters and in the ocean. (For a detailed discussion of the technology and economics of fisheries, see commercial fishing.) Another practical reason for studying fishes is their use in disease control. As predators on mosquito larvae, they help curb malaria and other mosquito-borne diseases.
Fishes are valuable laboratory animals in many aspects of medical and biological research. For example, the readiness of many fishes to acclimate to captivity has allowed biologists to study behaviour, physiology, and even ecology under relatively natural conditions. Fishes have been especially important in the study of animal behaviour, where research on fishes has provided a broad base for the understanding of the more flexible behaviour of the higher vertebrates. The zebra fish is used as a model in studies of gene expression.
There are aesthetic and recreational reasons for an interest in fishes. Millions of people keep live fishes in home aquariums for the simple pleasure of observing the beauty and behaviour of animals otherwise unfamiliar to them. Aquarium fishes provide a personal challenge to many aquarists, allowing them to test their ability to keep a small section of the natural environment in their homes. Sportfishing is another way of enjoying the natural environment, also indulged in by millions of people every year. Interest in aquarium fishes and sportfishing supports multimillion-dollar industries throughout the world.
Fishes have been in existence for more than 450 million years, during which time they have evolved repeatedly to fit into almost every conceivable type of aquatic habitat. In a sense, land vertebrates are simply highly modified fishes: when fishes colonized the land habitat, they became tetrapod (four-legged) land vertebrates. The popular conception of a fish as a slippery, streamlined aquatic animal that possesses fins and breathes by gills applies to many fishes, but far more fishes deviate from that conception than conform to it. For example, the body is elongate in many forms and greatly shortened in others; the body is flattened in some (principally in bottom-dwelling fishes) and laterally compressed in many others; the fins may be elaborately extended, forming intricate shapes, or they may be reduced or even lost; and the positions of the mouth, eyes, nostrils, and gill openings vary widely. Air breathers have appeared in several evolutionary lines.
Many fishes are cryptically coloured and shaped, closely matching their respective environments; others are among the most brilliantly coloured of all organisms, with a wide range of hues, often of striking intensity, on a single individual. The brilliance of pigments may be enhanced by the surface structure of the fish, so that it almost seems to glow. A number of unrelated fishes have actual light-producing organs. Many fishes are able to alter their coloration—some for the purpose of camouflage, others for the enhancement of behavioral signals.
Fishes range in adult length from less than 10 mm (0.4 inch) to more than 20 metres (60 feet) and in weight from about 1.5 grams (less than 0.06 ounce) to many thousands of kilograms. Some live in shallow thermal springs at temperatures slightly above 42 °C (100 °F), others in cold Arctic seas a few degrees below 0 °C (32 °F) or in cold deep waters more than 4,000 metres (13,100 feet) beneath the ocean surface. The structural and, especially, the physiological adaptations for life at such extremes are relatively poorly known and provide the scientifically curious with great incentive for study.
Almost all natural bodies of water bear fish life, the exceptions being very hot thermal ponds and extremely salt-alkaline lakes, such as the Dead Sea in Asia and the Great Salt Lake in North America. The present distribution of fishes is a result of the geological history and development of Earth as well as the ability of fishes to undergo evolutionary change and to adapt to the available habitats. Fishes may be seen to be distributed according to habitat and according to geographical area. Major habitat differences are marine and freshwater. For the most part, the fishes in a marine habitat differ from those in a freshwater habitat, even in adjacent areas, but some, such as the salmon, migrate from one to the other. The freshwater habitats may be seen to be of many kinds. Fishes found in mountain torrents, Arctic lakes, tropical lakes, temperate streams, and tropical rivers will all differ from each other, both in obvious gross structure and in physiological attributes. Even in closely adjacent habitats where, for example, a tropical mountain torrent enters a lowland stream, the fish fauna will differ. The marine habitats can be divided into deep ocean floors (benthic), mid-water oceanic (bathypelagic), surface oceanic (pelagic), rocky coast, sandy coast, muddy shores, bays, estuaries, and others. Also, for example, rocky coastal shores in tropical and temperate regions will have different fish faunas, even when such habitats occur along the same coastline.
Although much is known about the present geographical distribution of fishes, far less is known about how that distribution came about. Many parts of the fish fauna of the fresh waters of North America and Eurasia are related and undoubtedly have a common origin. The faunas of Africa and South America are related, extremely old, and probably an expression of the drifting apart of the two continents. The fauna of southern Asia is related to that of Central Asia, and some of it appears to have entered Africa. The extremely large shore-fish faunas of the Indian and tropical Pacific oceans comprise a related complex, but the tropical shore fauna of the Atlantic, although containing Indo-Pacific components, is relatively limited and probably younger. The Arctic and Antarctic marine faunas are quite different from each other. The shore fauna of the North Pacific is quite distinct, and that of the North Atlantic more limited and probably younger. Pelagic oceanic fishes, especially those in deep waters, are similar the world over, showing little geographical isolation in terms of family groups. The deep oceanic habitat is very much the same throughout the world, but species differences do exist, showing geographical areas determined by oceanic currents and water masses.
All aspects of the life of a fish are closely correlated with adaptation to the total environment, physical, chemical, and biological. In studies, all the interdependent aspects of fish, such as behaviour, locomotion, reproduction, and physical and physiological characteristics, must be taken into account.
Correlated with their adaptation to an extremely wide variety of habitats is the extremely wide variety of life cycles that fishes display. The great majority hatch from relatively small eggs a few days to several weeks or more after the eggs are scattered in the water. Newly hatched young are still partially undeveloped and are called larvae until body structures such as fins, skeleton, and some organs are fully formed. Larval life is often very short, usually less than a few weeks, but it can be very long, some lampreys continuing as larvae for at least five years. Young and larval fishes, before reaching sexual maturity, must grow considerably, and their small size and other factors often dictate that they live in a habitat different than that of the adults. For example, most tropical marine shore fishes have pelagic larvae. Larval food also is different, and larval fishes often live in shallow waters, where they may be less exposed to predators.
After a fish reaches adult size, the length of its life is subject to many factors, such as innate rates of aging, predation pressure, and the nature of the local climate. The longevity of a species in the protected environment of an aquarium may have nothing to do with how long members of that species live in the wild. Many small fishes live only one to three years at the most. In some species, however, individuals may live as long as 10 or 20 or even 100 years.
Fish behaviour is a complicated and varied subject. As in almost all animals with a central nervous system, the nature of a response of an individual fish to stimuli from its environment depends upon the inherited characteristics of its nervous system, on what it has learned from past experience, and on the nature of the stimuli. Compared with the variety of human responses, however, that of a fish is stereotyped, not subject to much modification by “thought” or learning, and investigators must guard against anthropomorphic interpretations of fish behaviour.
Fishes perceive the world around them by the usual senses of sight, smell, hearing, touch, and taste and by special lateral line water-current detectors. In the few fishes that generate electric fields, a process that might best be called electrolocation aids in perception. One or another of these senses often is emphasized at the expense of others, depending upon the fish’s other adaptations. In fishes with large eyes, the sense of smell may be reduced; others, with small eyes, hunt and feed primarily by smell (such as some eels).
Specialized behaviour is primarily concerned with the three most important activities in the fish’s life: feeding, reproduction, and escape from enemies. Schooling behaviour of sardines on the high seas, for instance, is largely a protective device to avoid enemies, but it is also associated with and modified by their breeding and feeding requirements. Predatory fishes are often solitary, lying in wait to dart suddenly after their prey, a kind of locomotion impossible for beaked parrot fishes, which feed on coral, swimming in small groups from one coral head to the next. In addition, some predatory fishes that inhabit pelagic environments, such as tunas, often school.
Sleep in fishes, all of which lack true eyelids, consists of a seemingly listless state in which the fish maintains its balance but moves slowly. If attacked or disturbed, most can dart away. A few kinds of fishes lie on the bottom to sleep. Most catfishes, some loaches, and some eels and electric fishes are strictly nocturnal, being active and hunting for food during the night and retiring during the day to holes, thick vegetation, or other protective parts of the environment.
Communication between members of a species or between members of two or more species often is extremely important, especially in breeding behaviour (see below Reproduction). The mode of communication may be visual, as between the small so-called cleaner fish and a large fish of a very different species. The larger fish often allows the cleaner to enter its mouth to remove gill parasites. The cleaner is recognized by its distinctive colour and actions and therefore is not eaten, even if the larger fish is normally a predator. Communication is often chemical, signals being sent by specific chemicals called pheromones.
Many fishes have a streamlined body and swim freely in open water. Fish locomotion is closely correlated with habitat and ecological niche (the general position of the animal to its environment).
Many fishes in both marine and fresh waters swim at the surface and have mouths adapted to feed best (and sometimes only) at the surface. Often such fishes are long and slender, able to dart at surface insects or at other surface fishes and in turn to dart away from predators; needlefishes, halfbeaks, and topminnows (such as killifish and mosquito fish) are good examples. Oceanic flying fishes escape their predators by gathering speed above the water surface, with the lower lobe of the tail providing thrust in the water. They then glide hundreds of yards on enlarged, winglike pectoral and pelvic fins. South American freshwater flying fishes escape their enemies by jumping and propelling their strongly keeled bodies out of the water.
So-called mid-water swimmers, the most common type of fish, are of many kinds and live in many habitats. The powerful fusiform tunas and the trouts, for example, are adapted for strong, fast swimming, the tunas to capture prey speedily in the open ocean and the trouts to cope with the swift currents of streams and rivers. The trout body form is well adapted to many habitats. Fishes that live in relatively quiet waters such as bays or lake shores or slow rivers usually are not strong, fast swimmers but are capable of short, quick bursts of speed to escape a predator. Many of these fishes have their sides flattened, examples being the sunfish and the freshwater angelfish of aquarists. Fish associated with the bottom or substrate usually are slow swimmers. Open-water plankton-feeding fishes almost always remain fusiform and are capable of rapid, strong movement (for example, sardines and herrings of the open ocean and also many small minnows of streams and lakes).
Bottom-living fishes are of many kinds and have undergone many types of modification of their body shape and swimming habits. Rays, which evolved from strong-swimming mid-water sharks, usually stay close to the bottom and move by undulating their large pectoral fins. Flounders live in a similar habitat and move over the bottom by undulating the entire body. Many bottom fishes dart from place to place, resting on the bottom between movements, a motion common in gobies. One goby relative, the mudskipper, has taken to living at the edge of pools along the shore of muddy mangrove swamps. It escapes its enemies by flipping rapidly over the mud, out of the water. Some catfishes, synbranchid eels, the so-called climbing perch, and a few other fishes venture out over damp ground to find more promising waters than those that they left. They move by wriggling their bodies, sometimes using strong pectoral fins; most have accessory air-breathing organs. Many bottom-dwelling fishes live in mud holes or rocky crevices. Marine eels and gobies commonly are found in such habitats and for the most part venture far beyond their cavelike homes. Some bottom dwellers, such as the clingfishes (Gobiesocidae), have developed powerful adhesive disks that enable them to remain in place on the substrate in areas such as rocky coasts, where the action of the waves is great.
The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants. Some have adhesive eggs. The mortality of the young and especially of the eggs is very high, and often only a few individuals grow to maturity out of hundreds, thousands, and in some cases millions of eggs laid.
Males produce sperm, usually as a milky white substance called milt, in two (sometimes one) testes within the body cavity. In bony fishes a sperm duct leads from each testis to a urogenital opening behind the vent or anus. In sharks and rays and in cyclostomes the duct leads to a cloaca. Sometimes the pelvic fins are modified to help transmit the milt to the eggs at the female’s vent or on the substrate where the female has placed them. Sometimes accessory organs are used to fertilize females internally—for example, the claspers of many sharks and rays.
In the females the eggs are formed in two ovaries (sometimes only one) and pass through the ovaries to the urogenital opening and to the outside. In some fishes the eggs are fertilized internally but are shed before development takes place. Members of about a dozen families each of bony fishes (teleosts) and sharks bear live young. Many skates and rays also bear live young. In some bony fishes the eggs simply develop within the female, the young emerging when the eggs hatch (ovoviviparous). Others develop within the ovary and are nourished by ovarian tissues after hatching (viviparous). There are also other methods utilized by fishes to nourish young within the female. In all live-bearers the young are born at a relatively large size and are few in number. In one family of primarily marine fishes, the surfperches from the Pacific coast of North America, Japan, and Korea, the males of at least one species are born sexually mature, although they are not fully grown.
Some fishes are hermaphroditic—an individual producing both sperm and eggs, usually at different stages of its life. Self-fertilization, however, is probably rare.
Successful reproduction and, in many cases, defense of the eggs and the young are assured by rather stereotypical but often elaborate courtship and parental behaviour, either by the male or the female or both. Some fishes prepare nests by hollowing out depressions in the sand bottom (cichlids, for example), build nests with plant materials and sticky threads excreted by the kidneys (sticklebacks), or blow a cluster of mucus-covered bubbles at the water surface (gouramis). The eggs are laid in these structures. Some varieties of cichlids and catfishes incubate eggs in their mouths.
Some fishes, such as salmon, undergo long migrations from the ocean and up large rivers to spawn in the gravel beds where they themselves hatched (anadromous fishes). Some, such as the freshwater eels (family Anguillidae), live and grow to maturity in fresh water and migrate to the sea to spawn (catadromous fishes). Other fishes undertake shorter migrations from lakes into streams, within the ocean, or enter spawning habitats that they do not ordinarily occupy in other ways.
The basic structure and function of the fish body are similar to those of all other vertebrates. The usual four types of tissues are present: surface or epithelial, connective (bone, cartilage, and fibrous tissues, as well as their derivative, blood), nerve, and muscle tissues. In addition, the fish’s organs and organ systems parallel those of other vertebrates.
The typical fish body is streamlined and spindle-shaped, with an anterior head, a gill apparatus, and a heart, the latter lying in the midline just below the gill chamber. The body cavity, containing the vital organs, is situated behind the head in the lower anterior part of the body. The anus usually marks the posterior termination of the body cavity and most often occurs just in front of the base of the anal fin. The spinal cord and vertebral column continue from the posterior part of the head to the base of the tail fin, passing dorsal to the body cavity and through the caudal (tail) region behind the body cavity. Most of the body is of muscular tissue, a high proportion of which is necessitated by swimming. In the course of evolution this basic body plan has been modified repeatedly into the many varieties of fish shapes that exist today.
The skeleton forms an integral part of the fish’s locomotion system, as well as serving to protect vital parts. The internal skeleton consists of the skull bones (except for the roofing bones of the head, which are really part of the external skeleton), the vertebral column, and the fin supports (fin rays). The fin supports are derived from the external skeleton but will be treated here because of their close functional relationship to the internal skeleton. The internal skeleton of cyclostomes, sharks, and rays is of cartilage; that of many fossil groups and some primitive living fishes is mostly of cartilage but may include some bone. In place of the vertebral column, the earliest vertebrates had a fully developed notochord, a flexible stiff rod of viscous cells surrounded by a strong fibrous sheath. During the evolution of modern fishes the rod was replaced in part by cartilage and then by ossified cartilage. Sharks and rays retain a cartilaginous vertebral column; bony fishes have spool-shaped vertebrae that in the more primitive living forms only partially replace the notochord. The skull, including the gill arches and jaws of bony fishes, is fully, or at least partially, ossified. That of sharks and rays remains cartilaginous, at times partially replaced by calcium deposits but never by true bone.
The supportive elements of the fins (basal or radial bones or both) have changed greatly during fish evolution. Some of these changes are described in the section below (Evolution and paleontology). Most fishes possess a single dorsal fin on the midline of the back. Many have two and a few have three dorsal fins. The other fins are the single tail and anal fins and paired pelvic and pectoral fins. A small fin, the adipose fin, with hairlike fin rays, occurs in many of the relatively primitive teleosts (such as trout) on the back near the base of the caudal fin.
The skin of a fish must serve many functions. It aids in maintaining the osmotic balance, provides physical protection for the body, is the site of coloration, contains sensory receptors, and, in some fishes, functions in respiration. Mucous glands, which aid in maintaining the water balance and offer protection from bacteria, are extremely numerous in fish skin, especially in cyclostomes and teleosts. Since mucous glands are present in the modern lampreys, it is reasonable to assume that they were present in primitive fishes, such as the ancient Silurian and Devonian agnathans. Protection from abrasion and predation is another function of the fish skin, and dermal (skin) bone arose early in fish evolution in response to this need. It is thought that bone first evolved in skin and only later invaded the cartilaginous areas of the fish’s body, to provide additional support and protection. There is some argument as to which came first, cartilage or bone, and fossil evidence does not settle the question. In any event, dermal bone has played an important part in fish evolution and has different characteristics in different groups of fishes. Several groups are characterized at least in part by the kind of bony scales they possess.
Scales have played an important part in the evolution of fishes. Primitive fishes usually had thick bony plates or thick scales in several layers of bone, enamel, and related substances. Modern teleost fishes have scales of bone, which, while still protective, allow much more freedom of motion in the body. A few modern teleosts (some catfishes, sticklebacks, and others) have secondarily acquired bony plates in the skin. Modern and early sharks possessed placoid scales, a relatively primitive type of scale with a toothlike structure, consisting of an outside layer of enamel-like substance (vitrodentine), an inner layer of dentine, and a pulp cavity containing nerves and blood vessels. Primitive bony fishes had thick scales of either the ganoid or the cosmoid type. Cosmoid scales have a hard, enamel-like outer layer, an inner layer of cosmine (a form of dentine), and then a layer of vascular bone (isopedine). In ganoid scales the hard outer layer is different chemically and is called ganoin. Under this is a cosminelike layer and then a vascular bony layer. The thin, translucent bony scales of modern fishes, called cycloid and ctenoid (the latter distinguished by serrations at the edges), lack enameloid and dentine layers.
Skin has several other functions in fishes. It is well supplied with nerve endings and presumably receives tactile, thermal, and pain stimuli. Skin is also well supplied with blood vessels. Some fishes breathe in part through the skin, by the exchange of oxygen and carbon dioxide between the surrounding water and numerous small blood vessels near the skin surface.
Skin serves as protection through the control of coloration. Fishes exhibit an almost limitless range of colours. The colours often blend closely with the surroundings, effectively hiding the animal. Many fishes use bright colours for territorial advertisement or as recognition marks for other members of their own species, or sometimes for members of other species. Many fishes can change their colour to a greater or lesser degree, by movement of pigment within the pigment cells (chromatophores). Black pigment cells (melanophores), of almost universal occurrence in fishes, are often juxtaposed with other pigment cells. When placed beneath iridocytes or leucophores (bearing the silvery or white pigment guanine), melanophores produce structural colours of blue and green. These colours are often extremely intense, because they are formed by refraction of light through the needlelike crystals of guanine. The blue and green refracted colours are often relatively pure, lacking the red and yellow rays, which have been absorbed by the black pigment (melanin) of the melanophores. Yellow, orange, and red colours are produced by erythrophores, cells containing the appropriate carotenoid pigments. Other colours are produced by combinations of melanophores, erythrophores, and iridocytes.
The major portion of the body of most fishes consists of muscles. Most of the mass is trunk musculature, the fin muscles usually being relatively small. The caudal fin is usually the most powerful fin, being moved by the trunk musculature. The body musculature is usually arranged in rows of chevron-shaped segments on each side. Contractions of these segments, each attached to adjacent vertebrae and vertebral processes, bends the body on the vertebral joint, producing successive undulations of the body, passing from the head to the tail, and producing driving strokes of the tail. It is the latter that provides the strong forward movement for most fishes.
The digestive system, in a functional sense, starts at the mouth, with the teeth used to capture prey or collect plant foods. Mouth shape and tooth structure vary greatly in fishes, depending on the kind of food normally eaten. Most fishes are predacious, feeding on small invertebrates or other fishes and have simple conical teeth on the jaws, on at least some of the bones of the roof of the mouth, and on special gill arch structures just in front of the esophagus. The latter are throat teeth. Most predacious fishes swallow their prey whole, and the teeth are used for grasping and holding prey, for orienting prey to be swallowed (head first) and for working the prey toward the esophagus. There are a variety of tooth types in fishes. Some fishes, such as sharks and piranhas, have cutting teeth for biting chunks out of their victims. A shark’s tooth, although superficially like that of a piranha, appears in many respects to be a modified scale, while that of the piranha is like that of other bony fishes, consisting of dentine and enamel. Parrot fishes have beaklike mouths with short incisor-like teeth for breaking off coral and have heavy pavementlike throat teeth for crushing the coral. Some catfishes have small brushlike teeth, arranged in rows on the jaws, for scraping plant and animal growth from rocks. Many fishes (such as the Cyprinidae or minnows) have no jaw teeth at all but have very strong throat teeth.
Some fishes gather planktonic food by straining it from their gill cavities with numerous elongate stiff rods (gill rakers) anchored by one end to the gill bars. The food collected on these rods is passed to the throat, where it is swallowed. Most fishes have only short gill rakers that help keep food particles from escaping out the mouth cavity into the gill chamber.
Once reaching the throat, food enters a short, often greatly distensible esophagus, a simple tube with a muscular wall leading into a stomach. The stomach varies greatly in fishes, depending upon the diet. In most predacious fishes it is a simple straight or curved tube or pouch with a muscular wall and a glandular lining. Food is largely digested there and leaves the stomach in liquid form.
Between the stomach and the intestine, ducts enter the digestive tube from the liver and pancreas. The liver is a large, clearly defined organ. The pancreas may be embedded in it, diffused through it, or broken into small parts spread along some of the intestine. The junction between the stomach and the intestine is marked by a muscular valve. Pyloric ceca (blind sacs) occur in some fishes at this junction and have a digestive or absorptive function or both.
The intestine itself is quite variable in length, depending upon the fish’s diet. It is short in predacious forms, sometimes no longer than the body cavity, but long in herbivorous forms, being coiled and several times longer than the entire length of the fish in some species of South American catfishes. The intestine is primarily an organ for absorbing nutrients into the bloodstream. The larger its internal surface, the greater its absorptive efficiency, and a spiral valve is one method of increasing its absorption surface.
Sharks, rays, chimaeras, lungfishes, surviving chondrosteans, holosteans, and even a few of the more primitive teleosts have a spiral valve or at least traces of it in the intestine. Most modern teleosts have increased the area of the intestinal walls by having numerous folds and villi (fingerlike projections) somewhat like those in humans. Undigested substances are passed to the exterior through the anus in most teleost fishes. In lungfishes, sharks, and rays, it is first passed through the cloaca, a common cavity receiving the intestinal opening and the ducts from the urogenital system.
Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes place. The gills are protected by a gill cover in teleosts and many other fishes but by flaps of skin in sharks, rays, and some of the older fossil fish groups. The blood capillaries in the gill filaments are close to the gill surface to take up oxygen from the water and to give up excess carbon dioxide to the water.
Most modern fishes have a hydrostatic (ballast) organ, called the swim bladder, that lies in the body cavity just below the kidney and above the stomach and intestine. It originated as a diverticulum of the digestive canal. In advanced teleosts, especially the acanthopterygians, the bladder has lost its connection with the digestive tract, a condition called physoclistic. The connection has been retained (physostomous) by many relatively primitive teleosts. In several unrelated lines of fishes, the bladder has become specialized as a lung or, at least, as a highly vascularized accessory breathing organ. Some fishes with such accessory organs are obligate air breathers and will drown if denied access to the surface, even in well-oxygenated water. Fishes with a hydrostatic form of swim bladder can control their depth by regulating the amount of gas in the bladder. The gas, mostly oxygen, is secreted into the bladder by special glands, rendering the fish more buoyant; the gas is absorbed into the bloodstream by another special organ, reducing the overall buoyancy and allowing the fish to sink. Some deep-sea fishes may have oils, rather than gas, in the bladder. Other deep-sea and some bottom-living forms have much-reduced swim bladders or have lost the organ entirely.
The swim bladder of fishes follows the same developmental pattern as the lungs of land vertebrates. There is no doubt that the two structures have the same historical origin in primitive fishes. More or less intermediate forms still survive among the more primitive types of fishes, such as the lungfishes Lepidosiren and Protopterus.
The circulatory, or blood vascular, system consists of the heart, the arteries, the capillaries, and the veins. It is in the capillaries that the interchange of oxygen, carbon dioxide, nutrients, and other substances such as hormones and waste products takes place. The capillaries lead to the veins, which return the venous blood with its waste products to the heart, kidneys, and gills. There are two kinds of capillary beds: those in the gills and those in the rest of the body. The heart, a folded continuous muscular tube with three or four saclike enlargements, undergoes rhythmic contractions and receives venous blood in a sinus venosus. It passes the blood to an auricle and then into a thick muscular pump, the ventricle. From the ventricle the blood goes to a bulbous structure at the base of a ventral aorta just below the gills. The blood passes to the afferent (receiving) arteries of the gill arches and then to the gill capillaries. There waste gases are given off to the environment, and oxygen is absorbed. The oxygenated blood enters efferent (exuant) arteries of the gill arches and then flows into the dorsal aorta. From there blood is distributed to the tissues and organs of the body. One-way valves prevent backflow. The circulation of fishes thus differs from that of the reptiles, birds, and mammals in that oxygenated blood is not returned to the heart prior to distribution to the other parts of the body.
The primary excretory organ in fishes, as in other vertebrates, is the kidney. In fishes some excretion also takes place in the digestive tract, skin, and especially the gills (where ammonia is given off). Compared with land vertebrates, fishes have a special problem in maintaining their internal environment at a constant concentration of water and dissolved substances, such as salts. Proper balance of the internal environment (homeostasis) of a fish is in a great part maintained by the excretory system, especially the kidney.
The kidney, gills, and skin play an important role in maintaining a fish’s internal environment and checking the effects of osmosis. Marine fishes live in an environment in which the water around them has a greater concentration of salts than they can have inside their body and still maintain life. Freshwater fishes, on the other hand, live in water with a much lower concentration of salts than they require inside their bodies. Osmosis tends to promote the loss of water from the body of a marine fish and absorption of water by that of a freshwater fish. Mucus in the skin tends to slow the process but is not a sufficient barrier to prevent the movement of fluids through the permeable skin. When solutions on two sides of a permeable membrane have different concentrations of dissolved substances, water will pass through the membrane into the more concentrated solution, while the dissolved chemicals move into the area of lower concentration (diffusion).
The kidney of freshwater fishes is often larger in relation to body weight than that of marine fishes. In both groups the kidney excretes wastes from the body, but the kidney of freshwater fishes also excretes large amounts of water, counteracting the water absorbed through the skin. Freshwater fishes tend to lose salt to the environment and must replace it. They get some salt from their food, but the gills and skin inside the mouth actively absorb salt from water passed through the mouth. This absorption is performed by special cells capable of moving salts against the diffusion gradient. Freshwater fishes drink very little water and take in little water with their food.
Marine fishes must conserve water, and therefore their kidneys excrete little water. To maintain their water balance, marine fishes drink large quantities of seawater, retaining most of the water and excreting the salt. Most nitrogenous waste in marine fishes appears to be secreted by the gills as ammonia. Marine fishes can excrete salt by clusters of special cells (chloride cells) in the gills.
There are several teleosts—for example, the salmon—that travel between fresh water and seawater and must adjust to the reversal of osmotic gradients. They adjust their physiological processes by spending time (often surprisingly little time) in the intermediate brackish environment.
Marine hagfishes, sharks, and rays have osmotic concentrations in their blood about equal to that of seawater and so do not have to drink water nor perform much physiological work to maintain their osmotic balance. In sharks and rays the osmotic concentration is kept high by retention of urea in the blood. Freshwater sharks have a lowered concentration of urea in the blood.
Endocrine glands secrete their products into the bloodstream and body tissues and, along with the central nervous system, control and regulate many kinds of body functions. Cyclostomes have a well-developed endocrine system, and presumably it was well developed in the early Agnatha, ancestral to modern fishes. Although the endocrine system in fishes is similar to that of higher vertebrates, there are numerous differences in detail. The pituitary, the thyroid, the suprarenals, the adrenals, the pancreatic islets, the sex glands (ovaries and testes), the inner wall of the intestine, and the bodies of the ultimobranchial gland make up the endocrine system in fishes. There are some others whose function is not well understood. These organs regulate sexual activity and reproduction, growth, osmotic pressure, general metabolic activities such as the storage of fat and the utilization of foodstuffs, blood pressure, and certain aspects of skin colour. Many of these activities are also controlled in part by the central nervous system, which works with the endocrine system in maintaining the life of a fish. Some parts of the endocrine system are developmentally, and undoubtedly evolutionarily, derived from the nervous system.
As in all vertebrates, the nervous system of fishes is the primary mechanism coordinating body activities, as well as integrating these activities in the appropriate manner with stimuli from the environment. The central nervous system, consisting of the brain and spinal cord, is the primary integrating mechanism. The peripheral nervous system, consisting of nerves that connect the brain and spinal cord to various body organs, carries sensory information from special receptor organs such as the eyes, internal ears, nares (sense of smell), taste glands, and others to the integrating centres of the brain and spinal cord. The peripheral nervous system also carries information via different nerve cells from the integrating centres of the brain and spinal cord. This coded information is carried to the various organs and body systems, such as the skeletal muscular system, for appropriate action in response to the original external or internal stimulus. Another branch of the nervous system, the autonomic nervous system, helps to coordinate the activities of many glands and organs and is itself closely connected to the integrating centres of the brain.
The brain of the fish is divided into several anatomical and functional parts, all closely interconnected but each serving as the primary centre of integrating particular kinds of responses and activities. Several of these centres or parts are primarily associated with one type of sensory perception, such as sight, hearing, or smell (olfaction).
The sense of smell is important in almost all fishes. Certain eels with tiny eyes depend mostly on smell for location of food. The olfactory, or nasal, organ of fishes is located on the dorsal surface of the snout. The lining of the nasal organ has special sensory cells that perceive chemicals dissolved in the water, such as substances from food material, and send sensory information to the brain by way of the first cranial nerve. Odour also serves as an alarm system. Many fishes, especially various species of freshwater minnows, react with alarm to a chemical released from the skin of an injured member of their own species.
Many fishes have a well-developed sense of taste, and tiny pitlike taste buds or organs are located not only within their mouth cavities but also over their heads and parts of their body. Catfishes, which often have poor vision, have barbels (“whiskers”) that serve as supplementary taste organs, those around the mouth being actively used to search out food on the bottom. Some species of naturally blind cave fishes are especially well supplied with taste buds, which often cover most of their body surface.
Sight is extremely important in most fishes. The eye of a fish is basically like that of all other vertebrates, but the eyes of fishes are extremely varied in structure and adaptation. In general, fishes living in dark and dim water habitats have large eyes, unless they have specialized in some compensatory way so that another sense (such as smell) is dominant, in which case the eyes will often be reduced. Fishes living in brightly lighted shallow waters often will have relatively small but efficient eyes. Cyclostomes have somewhat less elaborate eyes than other fishes, with skin stretched over the eyeball perhaps making their vision somewhat less effective. Most fishes have a spherical lens and accommodate their vision to far or near subjects by moving the lens within the eyeball. A few sharks accommodate by changing the shape of the lens, as in land vertebrates. Those fishes that are heavily dependent upon the eyes have especially strong muscles for accommodation. Most fishes see well, despite the restrictions imposed by frequent turbidity of the water and by light refraction.
Fossil evidence suggests that colour vision evolved in fishes more than 300 million years ago, but not all living fishes have retained this ability. Experimental evidence indicates that many shallow-water fishes, if not all, have colour vision and see some colours especially well, but some bottom-dwelling shore fishes live in areas where the water is sufficiently deep to filter out most if not all colours, and these fishes apparently never see colours. When tested in shallow water, they apparently are unable to respond to colour differences.
Sound perception and balance are intimately associated senses in a fish. The organs of hearing are entirely internal, located within the skull, on each side of the brain and somewhat behind the eyes. Sound waves, especially those of low frequencies, travel readily through water and impinge directly upon the bones and fluids of the head and body, to be transmitted to the hearing organs. Fishes readily respond to sound; for example, a trout conditioned to escape by the approach of fishermen will take flight upon perceiving footsteps on a stream bank even if it cannot see a fisherman. Compared with humans, however, the range of sound frequencies heard by fishes is greatly restricted. Many fishes communicate with each other by producing sounds in their swim bladders, in their throats by rasping their teeth, and in other ways.
A fish or other vertebrate seldom has to rely on a single type of sensory information to determine the nature of the environment around it. A catfish uses taste and touch when examining a food object with its oral barbels. Like most other animals, fishes have many touch receptors over their body surface. Pain and temperature receptors also are present in fishes and presumably produce the same kind of information to a fish as to humans. Fishes react in a negative fashion to stimuli that would be painful to human beings, suggesting that they feel a sensation of pain.
An important sensory system in fishes that is absent in other vertebrates (except some amphibians) is the lateral line system. This consists of a series of heavily innervated small canals located in the skin and bone around the eyes, along the lower jaw, over the head, and down the mid-side of the body, where it is associated with the scales. Intermittently along these canals are located tiny sensory organs (pit organs) that apparently detect changes in pressure. The system allows a fish to sense changes in water currents and pressure, thereby helping the fish to orient itself to the various changes that occur in the physical environment.

the inns and bothies.
Gift shops and tearooms stand in
for fishmongers, butchers and ironmongers.
Motors replaced sails,
the ubiquitous automobile has foregone the horse and cart.
Boats are for lazing on,
not now, for hauling in another hard-earned catch.
The credit card of tourists,
enjoying the now docile scene,
has paid for the landed fish of yesteryear,
accounted for in lives and a few shillings.
Is this progress?
Of course, but in any August the beauty of Polperro,
makes it a victim of its own success…
a dichotomy that makes me love this place, no less!
The shape of these old Tin Mine buildings is so pleasing. I guess if they were built today they would be a steel frame with some panelling bolted on to the outside and would have a prefabricated metal chimney. These techniques weren't available then, but even so I get the feeling that some effort was put into making them look pleasing. Why doesn't this happen these days? It seems all too often that when we put up a building now the drive for efficiency and cost control far outweigh any consideration for making the thing pleasing to the eye and making it enhance its' surroundings.
I'm sure these mines were pretty horrible to work in but at least these purely industrial buildings enhanced the landscape.
A fully functional Launch Abort System (LAS) with a test version of Orion attached, launches on NASA’s Ascent Abort-2 (AA-2) atop a Northrop Grumman provided booster on July 2, 2019, at 7 a.m. EDT, from Launch Pad 46 at Cape Canaveral Air Force Station in Florida. During AA-2, the booster will send the LAS and Orion to an altitude of 31,000 feet, traveling at Mach 1.15 (more than 1,000 mph). The LAS’ three motors will work together to pull the crew module away from the booster and prepare it for splashdown in the Atlantic Ocean. The flight test will prove that the abort system can pull crew to safety in the unlikely event of an emergency during ascent.

With a simple pull of the lever, these decorative figures can open and close their jaws like authentic nutcrackers!
Both of these models were built in the recent weeks leading up to Christmas. The design was pretty straightforward, but two major issues were making the faces look good, and finally getting the hats right. In fact, the green nutcracker's crown took the longest to figure out, and was finally made with hinge plates.
As mentioned in the tutorial, although these can in fact function as real nutcrackers, they're somewhat rickety and best suited for holiday decorations.
This old public toilet by the harbor appears to be used mainly by the fisherman who launch their boats nearby, but apparently someone was afraid a foreigner might wander by and not recognize the Japanese character for male, and decided a more universal symbol was also needed, just in case.
