This breeding bird shows the characteristic bill bump caused by circulating hormones. It is called a nuptial tubercle and is supposed to make them more attractive-presumably to other pelicans ! It will fall off at the end of the breeding season.
Titanopsis is a genus of about 10 species of succulent plants of the family Aizoaceae, indigenous to the arid regions of South Africa and Namibia. The name "Titanopsis" comes from the ancient Greek "titanos" (limestone) and "opsis" (looking like).
***
Without a doubt, 'the Concrete Leaf' is the most picturesque of the rare succulents. Its scientific name is titanopsis calcarea.
The nickname is due to its rough and rugged appearance. This gives the impression of mineral inlays on its fabrics.
It uses this mechanism to camouflage itself. In this way, birds and other animals do not perceive them among the rocks, on which it grows.
Here, we speak of one of South Africa's rare succulents. Its habits make it difficult to locate. That is precisely why it is so unusual.
***
They are small plants, with rosette up to 10 cm high.
Leaves are up to 3 cm with truncate tip and rough warty little tubercles at the apex of the leaves. They look like limestone and are hard to see in the wild.
Yellow flowers with 2 cm diameter appear in late fall.

Dactylorhiza fuchsii, the common spotted orchid, is a species of flowering plant in the orchid family Orchidaceae.
Dactylorhiza fuchsii is one of Europe's commonest wild orchids. It is widespread across much of Europe, with the range extending eastward into Siberia, Mongolia and Xinjiang. The species is also reportedly naturalised in the Canadian Province of Ontario.
Dactylorhiza fuchsii is a herbaceous perennial plant ranging from 10 to 60 centimetres (5 to 25 in) in height. The inflorescence is a dense-flowered spike, produced in June–August, that is at first conical then cylindrical. The flower colour can vary from white to pale purple with purple spots, a symmetrical pattern of dark purple loops or dots and dashes. The lip has three lobes. The bracts are usually shorter than the flower. The lip is smaller than that of the very similar Dactylorhiza maculata and has three deeper cuts. The middle lobe is more than half as large as a lateral lobe. Some colonies are highly perfumed, attractive to day-flying moths. The leaves are narrow lanceolate, keeled and often dark-spotted.

The humpback whale is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song typically lasting 4 to 33 minutes.

Chameleons are a distinctive and highly specialized clade of Old World lizards. The members of this family are best known for their distinct range of colors, being capable of shifting to different hues and degrees of brightness.
Some chameleon species are able to change their skin coloration. Different chameleon species are able to vary their coloration and pattern through combinations of pink, blue, red, orange, green, black, brown, light blue, yellow, turquoise, and purple.
Color change in chameleons has functions in camouflage, but most commonly in social signaling and in reactions to temperature and other conditions.
Chameleons tend to show brighter colors when displaying aggression to other chameleons,and darker colors when they submit or "give up". Some species, particularly those of Madagascar and some African genera in rainforest habitats, have blue fluorescence in their skull tubercles, deriving from bones and possibly serving a signaling role.
Very common in The Netherlands, so common that you get used to it. They are always there, the common house sparrow. Our Portuguese Laurel Tree is a common hiding place for the house sparrow. And not just to hide in it.
This year, though, there are a remarkable number of young sparrows active around the little tree.
The yellow edge at the beginning of the sparrow's beak caught my attention, especially since the background color in this photo does match it very well.
Consulting the internet on this subject yielded the following result ( source Wikipedia of course ! ) :
In bird anatomy, the gape is the interior of the open mouth of a bird, and the gape flange is the region where the two mandibles join together at the base of the beak. The width of the gape can be a factor in the choice of food.
Gapes of juvenile altricial birds are often brightly coloured, sometimes with contrasting spots or other patterns, and these are believed to be an indication of their health, fitness and competitive ability. Based on this, the parents decide how to distribute food among the chicks in the nest. Some species, especially in the families Viduidae and Estrildidae, have bright spots on the gape known as gape tubercles or gape papillae. These nodular spots are conspicuous even in low light.
A study examining the nestling gapes of eight passerine species found that the gapes were conspicuous in the ultraviolet spectrum (visible to birds but not to humans).
Parents may, however, not rely solely on the gape coloration, and other factors influencing their decision remain unknown.]
Interesting isn't it?

El barretet piramidal o flor caputxina, Anacamptis pyramidalis, és una orquídia nadiua de l'Europa central i meridional. El nom binomial té una etimologia confusa: ανα (ana: grec, 'esquena' o 'part del darrere') i κάμτειν (kamptein: grec, 'doblegat'), que es referiria possiblement als pol·linis o potser als sèpals corbats enfora; i pyramidalis del llatí ('piramidal') per la forma de la inflorescència.
És una planta perenne i resistent que creix fins a una alçada d'uns 30 cm tenint en compte la inflorescència. Les fulles són oblongues d'uns 5 cm i creixen dels tubercles subterranis que són rodons i amb una mida màxima de 6 cm. El color de la flor varia del rosa al lila, i rarament el blanc. La seva olor és forta i rància. La forma compacta i piramidal de la inflorescència és molt característica d'aquesta espècie i dona lloc al seu nom comú. Les flors són pol·linitzades per lepidòpters.

Mammillaria zeilmanniana is a cactus endemic to Mexico. Its natural habitat the daytime temperatures are quite high and the nights are cool. It grows on steep of volcanic rock (igneous) face in canyon walls in semi-desert and deciduous forests.
Mammillaria zeilmanniana is one of the most beautiful Mammillaria. It is an exception from the general rule that red-flowered cactus of this genus do not bloom until they are several years old. It produces a profusion of deep carmine-red flowers while still quite young and small.
The young cactus is solitary but slowly forms a cluster of individual nearly globular stems, which are glossy green and usually about 6cm (2.3 inch) high and 5cm (2 inch) across. A four-year-old specimen is likely to fill a 10cm (4 inch) container. The tubercles are 6mm (2.3 inch) high and each areole has 15 to 18 radial white and 2 to 4 central brown spines, all about 1-2cm (0.4-0.8 inch) long. One of the centrals is hooked.
Mammillaria zeilmanniana flowers during the summer sometimes followed by brightly coloured fruits. The flowers, placed in circle close to the apex, originate from the aureola at the base of the tubercles, bell-shaped, with a diameter of 1.8-2 cm (0.7-0.8 inch) and keep open for almost one week; the blossoming lasts the whole summer.
Phyllidia polkadotsa is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Phyllidiidae. This nudibranch has a yellow or orange coloured dorsum with large round black spots. There are three longitudinal ridges along the back and small, scattered, tubercles.

This is a baby Humpback Whale breaching off the tip of the Baja peninsula. You can see here that it has its eye closed during the breach. It appeared to be copying its mother, who was enormous and breaching spectacularly, but the youngster could not achieve such a big splash. Humpbacks usually have lots of barnacles attached, particularly on the face and flippers, but this one is too young for these. Those rows of tubercles on the face are a normal part of a Humpback Whale.

Dioctria rufipes can reach a body length of about 8–15 mm (0.31–0.59 in) and a wings length of 7.5–9 mm (0.30–0.35 in). These medium-large robber flies have a black head and hard piercing mouthparts. The antennal tubercle is well-developed above the eyes. The mesothorax is black, lightly pubescent, with inconspicuous longitudinal stripes. The abdomen is slender, dorsally wider towards the back. The front legs are completely orange-red, whereas the hind legs are mainly black. They show a complete stripe of pale, short and soft pubescence (tomentum) on the sides of the thorax (pleura), with an additional ventral stripe above middle coxa.
Porcellio scaber has an oval body, can grow up to 20 millimetres (0.79 in) long, and is usually a grey colour, paler underneath, although brown, blue, yellow, or pinkish hues may also be observed (like many other woodlice, a red variety can often be found in coastal areas[citation needed]). The dorsal (upper) surface of its segmented exoskeleton is covered in a series of small tubercles hence its common name.
At the head it has two pairs of antennae, with the inner pair being very small. Two compound eyes are located on the dorsal side of the head, while the mouth parts are on the ventral (lower) side.
There are 7 pairs of legs, corresponding to the 7 segments of the thorax. The short abdomen consists of 6 segments. On the ventral side of the abdomen there are two whitish pseudo-lungs, connected with pores to the outside air. At the rear end there is a small telson flanked by a pair of appendages known as uropods.

The pygmy seahorse (Hippocampus bargibanti) measure less than one inch in length (2 cm), and is naturally well camouflaged and extremely difficult to see amongst the gorgonian coral it lives on. The relationship between a pygmy seahorse and its host sea-fan is non-invasive and non-parasitic, serving only to shelter the diminutive seahorse. There are two known color variations, grey with red tubercles and yellow with orange tubercles. It is unknown whether or not, though speculated that, these color varieties are linked to specific host gorgonians (corals). (Wikipedia)

First, I thought I encountered Deutonura conjuncta, because we are quite far from the Pyrenees.
But I see two setae on the dorso-internal tubercles of the 1st thoracic segment.
I believe there are only 2 bristles on the dorso-lateral tubercles of the 1st to 3rd abdominal segment (but an indication of their position on my photo would help me because I am not sure of their location).
So it would rather be a somewhat nordic monticola?

At the anterior end the rostrum projects between the eyes and is split into 2 tapering parts that touch at their tips. The first pair of abdominal limbs, or pleopods, bear pincers and are shorter and stouter than pairs 2-5, which are long, slender and spider-like. The carapace has a few large tubercles and may be covered with encrusting invertebrates."

Els coreids o corèids (Coreidae) són una nombrosa família constituïda per insectes succionadors de saba, classificats en l'ordre de Hemiptera, al subordre Heteroptera.
Els membres de la família Coreidae són cosmopolites, però la majoria de les espècies són tropicals o subtropicals.La forma del cos és fora variable; algunes espècies són, en termes generals, ovalades; altres són allargades amb costats paral·lels, i una minoria són esveltes. Tenen antenes compostes per quatre segments, nombroses venes en la membrana de les ales, i glàndules de pudor externament visibles. Varien en grandària de 7 a 45 mm de llarg, el que significa que la família inclou algunes de les espècies més grosses del subordre Heteroptera.Algunes espècies tenen notables expansions en forma de fulla a les tíbies de les potes del darrere. Altres espècies estan cobertes amb espines i tubercles.

Catacoeloceras is a genus of ammonite that lived during the Early Jurassic, specifically in the Toarcian stage, approximately 183 to 175 million years ago. Its fossils are characteristic of the marine deposits of Millau, in the Aveyron department of France, a classic European locality for Jurassic paleontology. These ammonites are key index fossils, used to identify and date the "Bifrons Zone" of the Toarcian.
The shell of Catacoeloceras is evolute, meaning the inner whorls are clearly visible. It has a distinctive subquadrate (almost square) whorl section and is adorned with strong, straight, and simple ribs that cross the entire flank. The key and most distinctive feature of the genus is the presence of two rows of tubercles or spines on the ventral region (the outer rim), which are separated by a smooth groove.
These cephalopods inhabited the shallow to moderately deep seas of the Tethys Ocean that covered much of present-day Europe. Their fossils in the Millau region are often found well-preserved in marly limestone nodules, sometimes retaining fine details of the shell structure.

The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera.
The adult humpback whale is generally 14–15 m (46–49 ft), though longer lengths of 16–17 m (52–56 ft) have been recorded. Females are usually 1–1.5 m (3 ft 3 in – 4 ft 11 in) longer than males.
The species can reach body masses of 40 metric tons (44 short tons). Calves are born at around 4.3 m (14 ft) long with a weight of 680 kg (1,500 lb).
The body is bulky with a thin rostrum and proportionally long flippers, each around one-third of its body length.[15][16] It has a short dorsal fin that varies from nearly non-existent to somewhat long and curved.
As a rorqual, the humpback has grooves between the tip of the lower jaw and the navel. They are relatively few in number in this species, ranging from 14–35. The mouth is lined with baleen plates, which number 270-400 for both sides.
Unique among large whales, humpbacks have bumps or tubercles on the head and front edge of the flippers; the tail fluke has a jagged trailing edge.
The tubercles on the head are 5–10 cm (2.0–3.9 in) thick at the base and poke up to 6.5 cm (2.6 in). They are mostly hollow in the center, often containing at least one fragile hair that erupts 1–3 cm (0.39–1.18 in) from the skin and is 0.1 mm (0.0039 in) thick. The tubercles develop early in the womb and may have a sensory function as they are rich in nerves.
The dorsal or upper-side of the animal is generally black; the ventral or underside has various levels of black and white coloration. Whales in the southern hemisphere tend to have more white pigmentation. The flippers can vary from all-white to white only on the undersurface.
The varying color patterns and scars on the tail flukes distinguish individual animals. The end of the genital slit of the female is marked by a round feature, known as the hemispherical lobe, which visually distinguishes males and females.

Amaltheus gibbosus is a species of ammonite from the Early Jurassic, more precisely from the Pliensbachian stage, around 190 to 183 million years ago. Due to its rapid evolution and wide geographic distribution, it serves as an excellent index fossil, helping geologists date rock layers with high precision.
Its fossils are found in the marine deposits of Millau, in the Aveyron department of southern France, a region well known for its Jurassic outcrops. These ammonites lived in shallow seas that once covered much of what is now Europe, where they coexisted with other marine fauna such as belemnites, bivalves, and other cephalopods.
The species is recognizable by its compressed, involute shell, with outer whorls largely covering the inner ones. It likely exhibited sexual dimorphism, with larger macroconchs (inferred females) and smaller microconchs (inferred males). The ribs are strong and radial, sometimes ending in rounded tubercles near the ventrolateral area. One of the defining features is the sharp, often crenulated keel that runs along the venter—the outer edge of the shell—without any accompanying grooves. This keel gives the species a streamlined appearance, typical of many fast-moving, nektonic ammonites.

In Millau, fossils of A. gibbosus are typically found in marl and limestone layers. The preservation is often good enough to show the ribbing, the shape of the whorls, and the ventral keel. Specimens are usually collected from nodules or split bedding planes. While not all are complete, the key morphological traits remain easy to identify.

Cylindropuntia is a genus of cacti (family Cactaceae), containing species commonly known as chollas (/ˈtʃɔɪəz/ CHOY-əz), native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant.
Trachyceras multituberculatum is an impressive ammonite from the Carnian stage of the Late Triassic, found mainly in the marine rocks of Guizhou Province, southern China. Most fossils are discovered in thin layers of limestone and shale, often as single shells or fragments. This species is important for paleontologists because it serves as an “index fossil,” helping to date and compare rock layers across different regions of the ancient Tethys Ocean. The best-known examples come from the Xiaowa Formation, especially the famous fossil sites of Guanling and Xingyi, though a few have turned up in neighboring Yunnan and Sichuan. Finding a complete and well-preserved specimen is quite rare—less than 5% of all finds—but even partial or internal molds are prized, especially when they show the unique bumps and ribs that set this species apart. Most Trachyceras fossils from Guizhou are preserved as shiny, pyritized molds, a sign of the oxygen-poor, deep-water conditions that existed over 230 million years ago.

Superfamily: Trachyceratoidea
Family: Trachyceratidae
Genus: Trachyceras
Species: Trachyceras multituberculatum
Era: Mesozoic
Period: Triassic (Carnian, ~237–227 Ma)
Origin: Guizhou Province, China
Diameter of the larger pictured specimen: 44 mm
The shell of Trachyceras multituberculatum is thick and disk-shaped, with a somewhat triangular cross-section, flat sides, and an angular edge. It’s easily recognized by its strong ribs and rows of spiny bumps (called tubercles), which make it stand out from other ammonites of the time. These ammonites lived in open marine environments alongside a rich variety of marine reptiles—like ichthyosaurs, thalattosaurs, placodonts, and early turtles—and many other ammonites.
Although the original shell material is gone, the fossils beautifully capture the characteristic ornamentation and fine details of the species. This type of preservation is the most common way Trachyceras fossils are found today—and such specimens remain highly valued, both for their scientific importance and for the unique glimpse they provide into the ancient marine world.
Phyllidia babai is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Phyllidiidae.
The specific name babai is in honor of the Japanese malacologist Kikutaro Baba. This nudibranch has a cream to light yellow coloured dorsum with white tubercles in the center of black rings and the mantle finely edged in yellow. The clavus of each rhinophore has 21 to 24 lamellae, and the rhinophoral pocket is trimmed in white. Its white-coloured, pointed, oral tentacles have lateral grooves, and they also are trimmed in yellow. The ventral surface is a pale cream colour. This species feeds on the yellow sponge, Acanthella stipata. (Wikipedia) Lembeh Strait, North Sulawesi, Indonesia
Dioctria rufipes, the common red-legged robberfly, is a species of robber fly in the subfamily Dasypogoninae of the family Asilidae....Dioctria rufipes can reach a body length of about 8–15 mm (0.31–0.59 in) and a wings length of 7.5–9 mm (0.30–0.35 in). These medium-large robber flies have a black head and hard piercing mouthparts. The antennal tubercle is well-developed above the eyes..Adults can be found from May to July–August.These insects are predators on other insects.
M. butleri shows distinctive 'hourglass' pattern that is bordered by two golden lines (see photo).

Nice gecko, which we found in one evening inside the room where we were living in Croatia :)
The Mediterranean house gecko (Hemidactylus turcicus) is a species of house gecko common to the Mediterranean area which has spread to many parts of the world. It is commonly referred to as the Turkish gecko. It's a very small lizard generally measuring between 10–12,5 cm in length, with sticky toe pads, vertical pupils, and large eyes that lack eyelids. Their skin is light brown or grayish above, spotted with darker; many of the tubercles white, lower surfaces white. They may be completely translucent except for the spotting. Some are darker. Turkish geckos can be found in areas near human presence such as university campuses, cemeteries, coastal regions, and shrublands. In these urban or suburban areas, they are typically seen in the cracks of old brick buildings. They can also be found in other areas like mountain cliffs and caves. The Mediterranean house geckos feed on crickets, grasshoppers, cockroaches, spiders, beetles, moths, butterflies, ants, isopods, and snails.

Uroczy gekonek, którego znaleźliśmy pewnego wieczoru pod sufitem w naszej kwaterze w Chorwacji :)
Gekon turecki (Hemidactylus turcicus) – gatunek gada z rodziny gekonów występujący w południowej i południowo-wschodniej części Półwyspu Iberyjskiego i południowej Francji, na północno-wschodnim wybrzeżu Adriatyku, Półwyspie Bałkańskim, a także na wyspach Morza Śródziemnego i Egejskiego. Występuje też na Wyspach Kanaryjskich, w Azji Mniejszej i na Półwyspie Arabskim. Ubarwienie gekona jest zmienne, zależy od środowiska i nastroju zwierzęcia. Zazwyczaj waha się od brązowo-różowego po żółty. Na palcach znajdują się przylgi umożliwiające zwierzęciu wspinanie się po stromych powierzchniach. Długość ciała - do 12,5 cm. Żyje w wielu różnorodnych siedliskach, zarówno na obszarach skalistych, nadmorskich klifach jak i na terenach zielonych zdominowanych przez roślinność krzewiastą. Może zamieszkać w pobliżu siedzib ludzkich. Żywi się owadami i pajęczakami, rzadko zjada małe jaszczurki. Czasem korzysta ze sztucznych źródeł światła, by łowić zwabione blaskiem owady.
I think conjuncta, but is the only way to distinguish monticola the altitude ? But from how much meters ? Here 300m.
Ammonites are a group of extinct molluscs which somewhat resembled a shelled squid when they were alive.
These ancient sea creatures had tentacles like the modern octopus, and spiral shells like Nautilus creatures.
They first appeared on the fossil record 240 million years ago, in the Triassic Period, and died out 65 million years ago with the dinosaurs during the Cretaceous-Tertiary Mass Extinction Event.
The fossilised remains of these sea creatures are perhaps the most popular fossils on the market today.
This particular ammonite is a member of the Cleoniceras species of ammonites.

Phylum:Mollusca
Class:Cephalopoda
Subclass:Ammonoidea
Order:Ammonitida
Superfamily:Hoplitaceae
Family:Hoplitidae
Genus:Cleoniceras
Species: Cleoniceras sp.
Era: Mesozoic
Period: Cretaceous
Origin: Mahajanga (Madagascar)
Description: Iridescent Ammonite. No restorations, 100% natural.
Cleoniceras is a rather involute, high-whorled hoplitid from the Lower to basal Middle Albian of Europe, Madagascar, and the Transcaspian region. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls.
Cleoniceras is included in the subfamily Cleoniceratinae.
Dioctria rufipes can reach a body length of about 8–15 mm (0.31–0.59 in) and a wings length of 7.5–9 mm (0.30–0.35 in). These medium-large robber flies have a black head and hard piercing mouthparts. The antennal tubercle is well-developed above the eyes. The mesothorax is black, lightly pubescent, with inconspicuous longitudinal stripes. The abdomen is slender, dorsally wider towards the back. The front legs are completely orange-red, whereas the hind legs are mainly black. They show a complete stripe of pale, short and soft pubescence (tomentum) on the sides of the thorax (pleura), with an additional ventral stripe above middle coxa.

Cylindropuntia is a genus of cacti (family Cactaceae), containing species commonly known as chollas (/ˈtʃɔɪəz/ CHOY-əz), native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant.
