I did manage to find some interesting subjects to shoot, but hands-down the most exciting part of the day was this 8-9 foot long swordfish we found sunning itself in the channel just below the silky smooth surface.
This is a direct result of Nathan's SHIP and Mahj's Khagaan. Still need to make the tools/equipment for the ground crew and will then shoot all the final pics of the Xiphias and launch site.
This is one of the threatened Madeira speckled wood butterflies and the only one I have seen in two visits to the island. It was photographed in the Blandy Estate, Palheiro Gardens, in Funchal.
Although the white spot on the leading edge of the forewing is poorly developed it can be identified because there are only two eye spots on the hindwing. The usual speckled wood has three or even four.

Got 'er finished off last night apart from some stickering. Leaves me a week to build a launch pad and take some proper pics...although really wishing I actually knew how to effectively Photoshop because she is just screaming for some swooshy spacey backgrounds :P
Following a rigorous elimination process, the two test pilots for Thales Orbital Defence's Xiphias Project have been selected. Only synthoid and robotic applicants had been accepted into the selections phase due to the high g-forces that the prototype interceptor is estimated to generate. This has also allowed only the bare minimum of life support systems to be needed during the early development stages of the craft. Thales' management did have a bit of an HR disaster on their hand's when human and cyborg employees voiced their grievances on social media. It made matters worse when the announcement of the test pilots coincided with the appointment of Lement Vardisingh as the first synthoid CEO of a major weapons manufacturer. However, the waters were calmed when Vardisingh announced that the production model of the Xiphias will be produced in both a human/cyborg, as well as, synthoid/robotic cockpit configurations. As well, a new team was formed within the Flight Systems & Avionics division to further develop high-g pilot pods for non-synth pilots.
The success of this controversial project remain to be seen, although hopes are high that it will be the most capable fast response lunar/station based interceptor on the market.
Swordfish (Xiphias gladius ; from Greek ξίφος: sword, and Latin gladius: sword), also known as Broadbill in some countries, are large, highly migratory, predatory fish characterized by a long, flat bill. They are a popular sport fish of the billfish category, though elusive. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish can live close to shore. They reach a maximum size of 14 ft 9 in (455 cm) and 1,400 lb (650 kg). The International Game Fish Association's all-tackle angling record for a swordfish was a 1,182 lb (536.15 kg) specimen taken off Chile in 1953.

The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic ecozone. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria,[1] Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.
The speckled wood belongs to the genus Pararge, which comprises three species: Pararge aegeria, Pararge xiphia, and Pararge xiphioides. Pararge xiphia occurs on the Atlantic island of Madeira. Pararge xiphioides occurs on the Canary Islands. Molecular studies suggest that the African and Madeiran populations are closely related and distinct from European populations of both subspecies, suggesting that Madeira was colonized from Africa and that the African population has a long history of isolation from European populations. Furthermore, the species Pararge aegeria comprises four subspecies: Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. These subspecies stem from the fact that the speckled wood butterfly exhibits a cline across their range. This butterfly varies morphologically down the 700 km cline, resulting in the different subspecies corresponding to geographical areas.
The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.
The morphology of this butterfly varies as a gradient down its geographic cline from north to south. The northern butterflies in this species have a bigger size, adult body mass, and wing area. These measurements decrease as one moves in a southerly direction in the speckled wood's range. Forewing length on the other hand increases moving in a northerly direction. This is due to the fact that in the cooler temperatures of the northern part of this butterfly's range, the butterflies need larger forewings for thermoregulation. Finally, the northern butterflies are darker than their southern counterpart, and there is a coloration gradient, down their geographical cline.
The speckled wood occupies a diversity of grassy, flowery habitats in forest, meadow steppe, forest, woods, and glades. It can also be found in urban areas alongside hedges, in wooded urban parks, and occasionally in gardens. Within its range the speckled wood typically prefers damp areas. It is generally found in woodland areas throughout much of the Palearctic ecozone. P. a. tircis is found in northern and central Europe, Asia Minor, Syria, Russia, and central Asia, and the P. a. aegeria is found in southwestern Europe and North Africa.[1] Two additional subspecies are found within the British Isles: the Scottish speckled wood (P. a. oblita) is restricted to Scotland and its surrounding isles, and the Isles of Scilly speckled wood (P. a. insula) is found only on the Isles of Scilly. P. a. tricis and P. a. aegeria gradually intergrade into each other.
The eggs are laid on a variety of grass host plants. The caterpillar is green with a short, forked tail, and the chrysalis (pupa) is green or dark brown. The species is able to overwinter in two totally separated developmental stages, as pupae or as half-grown larvae. This leads to a complicated pattern of several adult flights per year.

These treehopper nymphs (black and white: Guayaquila xiphias, Membracidae & Aetalion reticulatum, Aetalionidae) were filmed in the Amazon rainforest of Ecuador. They feed upon sugar containing sap of a plant. Excess sap is excreted as honeydew which is collected by ants (Camponotus sp.) that feed upon the sugar and, in return, protect the treehoppers from predators. This is an example of mutualism, a form of symbiosis where both species benefit.

Swordfish (Xiphias gladius), also known as broadbills in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill. They are a popular sport fish of the billfish category, though elusive. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,234 m. They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m (14 ft 11 in) in length and 650 kg (1,430 lb) in weight.

I'd say the length of this swordfish was around 3 metres. The swordfish is the largest billfish, up to 15 ft (4.5 m) and 1,300 lbs (600 kg).
It is one of the fastest fish in the ocean (50-60 mph or more).
This picture is fairly similar to that image: www.flickr.com/photos/pierre_et_nelly/9423515240/, but this one shows the animal's belly and I thought it might be interesting.

Description
The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females.[2] Females have brighter and more distinct markings than males.

Finally, the northern butterflies are darker than their southern counterpart, and there is a coloration gradient, down their geographical cline.[3]
Habitat and range
The speckled wood occupies a diversity of grassy, flowery habitats in forest, meadow steppe, woods, and glades. It can also be found in urban areas alongside hedges, in wooded urban parks, and occasionally in gardens. Within its range the speckled wood typically prefers damp areas.[2] It is generally found in woodland areas throughout much of the Palearctic realm. P. a. tircis is found in northern and central Europe, Asia Minor, Syria, Russia, and central Asia, and the P. a. aegeria is found in southwestern Europe and North Africa.[1] Two additional subspecies are found within the British Isles: the Scottish speckled wood (P. a. oblita) is restricted to Scotland and its surrounding isles, and the Isles of Scilly speckled wood (P. a. insula) is found only on the Isles of Scilly.[2] P. a. tircis and P. a. aegeria gradually intergrade into each other.[1]
Mating behavior
In the speckled wood butterfly females are monandrous; they typically only mate once within their lifetime. On the other hand, males are polygynous and typically mate multiple times.[10] In order to locate females, males employ one of two strategies: territorial defense and patrolling.[4]
During territorial defense, the male defends a sunny spot in the forest, waiting for females to stop by. Another strategy is patrolling, during which males fly through the forest actively searching for females.[4] Then, the female must make a choice between mating with a patrolling male or a territorial male. By mating with a territorial male, a female can be sure that she has chosen a high quality male, as the ability to defend a territory reflects the genetic quality of a male. Therefore, by choosing a territorial male, the female is being more picky about which male she chooses to mate with.[6]
The choice is most likely dependent on the search costs associated with finding a mate. When actively searching for a male, a female must spend her precious time and energy, which results in search costs, especially when she has a limited life span. As search costs increase, female choosiness for a mate decreases. For example, if a female's life span is shorter, she has a higher cost associated with searching for the ideal mate. Therefore, she is likely to mate within a day of her emergence as an adult, and will most likely mate with a patrolling male, as they are easier to find. However, if a female lifespan is longer, then the search costs associated with finding a mate are lower. The female is then more likely to actively search for a territorial male. Since the search costs vary depending on environmental conditions, strategies vary from population to population.[6]
Males employing different strategies, territorial defense or patrolling, can be differentiated by the number of spots on their hindwings. Those with three spots are more likely to be patrolling males, while those with four spots are more likely to be defending males. The frequency of the two phenotypes depends on the location and time of year. For example, there are more territorial males in areas where there are many sunny spots. Furthermore, the development of wingspots is influenced by environmental conditions. Therefore, the strategy employed by males is heavily dependent on environmental conditions.[4]
Territorial behavior
Territorial defense involves a male flying or perching in a spot of sunlight that pierces through the forest canopy. The speckled wood butterfly spends the night high up in the trees, and territorial activity commences once sunlight passes through the canopy. The males often remain in the same sunspot until the evening, following the sunspot as it moves across the forest floor. The males often perch on vegetation near the forest floor. If a female flies into the territory, the resident male flies after her, the pair drop to the ground, and copulation follows. If another species flies through the sunspot, the resident male ignores the intruder.[11]
However, if a conspecific, a male of the same species, enters the sunspot, the resident male flies towards the intruder almost bumping into him, and the pair fly upwards. The winner flies back towards the forest floor within the sunspot, while the defeated male flies away from the territory.[11] The pattern of flight during this encounter depends on the vegetation. In an open understory, the pair fly straight upwards. In a dense understory, this flight pattern is not possible, so the pair spiral upwards.[5]
In most of these interactions, the conflict is relatively short, and the resident male wins. The intruder most likely backs down as a serious confrontation could be costly, and there is an abundance of equally desirable sunspots. However, if both males believe they are the "resident" male, the conflict escalates.[11] If a previous owner of the sunspot tries to reclaim his territory after he has left for mating, a longer and more costly fight ensues. In these serious fights, the winner of the contest is not predictable.[5]
The abundance of territorial behavior depends on the environmental conditions. At the beginning of the mating season, fights over ownership of a sunspot territory are lengthy. The duration of the conflict quickly decreases during a period of two weeks. This pattern is correlated with the progression of the season, as temperature and male density rise. Sunspots are more attractive when temperatures are low, as they provide the warmth needed for higher levels of activity. As male density increases, it becomes increasingly difficult to hold onto a territory, so territoriality decreases and more males exhibit patrolling behavior.[5]
Asymmetry and territoriality
In butterflies, asymmetrical wings are observed in three different ways: fluctuating (small, random variations from the standard bilateral symmetry), directional (variations that are biased towards a particular side so one wing is larger than the other), and antisymmetry (similar to directional but half of the individuals of the species find that a particular wing, such as their left, is larger, and the other half of the individuals find that their right is larger.[12]
Both genders of the speckled wood butterfly exhibit asymmetrical wings; however, only males show directional asymmetry (likely to be caused by genetic factors).[12] Also, females show more asymmetry in general compared to males. Within male speckled wood butterflies, the melanic form shows greater directional asymmetry and grows more slowly than the pale, territorial males. Furthermore, males that are most successful in territorial disputes are only slightly asymmetrical, as opposed to complete symmetry or asymmetry; this indicates that sexual selection affects asymmetry.[12]

THE FISHERMAN
Captain John Gibbs
F/V Southern Horizon
"This week we are providing you with swordfish landed in one of the highly migratory species exempted fishing permits (EFPs) currently active off the coast of California. These EFPs are intended to test new and old fishing methods that target swordfish and other pelagic species, while avoiding bycatch and overfishing.
Your shares this week are from the F/V Southern Horizon which uses longlines, both shallow and deep set, to catch swordfish in a special EFP with only this vessel and one other vessel allowed to fish in this area with this gear for the next two years. Longlines are horizontally strung lines that can be up to 100 meters long, supported on each end by surface floats. Smaller vertical lines hang down from the main line every few feet, kind of like Christmas lights, ending with a single hook. Each hook is designed to catch a single swordfish. This EFP is required to operate outside of leatherback sea turtle critical habitat, have observers on every vessel, only set their lines at night to avoid sea bird bycatch, and a few other important measures to protect non-target species."
SPECIES
Swordfish
xiphias gladius
Swordfish are one of the most formidable predators in the sea. They possess amazing eyesight to accurately locate prey, and their flesh consists primarily of 'white' muscle which provides energy for sudden bursts of activity. The swordfish then uses its bill to stun or impale its victim, slashes it into pieces or swallows it whole. Swordfish feed during the day, primarily on squid, but also fish and occasionally crustaceans. They undertake vertical migrations in the ocean, following the movement of many small shrimp, fish and squid that move with the changing light intensity in a (somewhat unsuccessful) attempt to avoid predators. Unlike some fish, swordfish are unable to maintain a body temperature higher than the temperature of the surrounding water. Instead, they have a unique muscle and brown tissue that warms blood flowing to the brain and eyes, enabling it to tolerate the extreme cold of the ocean depths. Swordfish also undertake lengthy seasonal migrations, to temperate or cold waters in the summer where they feed, and back to warm waters in autumn for spawning.
