Mediterranean Sea 16
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Bluntnose Sixgill Shark
The bluntnose sixgill shark (''Hexanchus griseus''), often simply called the cow shark, is the largest hexanchoid shark, growing to in length. It is found in tropical and temperate waters worldwide and its diet is widely varied by region. The bluntnose sixgill is a species of sixgill sharks, of genus ''Hexanchus'', a genus that also consists of two other species: the bigeye sixgill shark ( ''Hexanchus nakamurai'') and the Atlantic sixgill shark ( ''Hexanchus vitulus''). Through their base pairs of mitochondrial genes COI and ND2, these three species of sixgills widely differ from one another. Taxonomy The first scientific description of the bluntnose sixgill shark was authored in 1788 by Pierre Joseph Bonnaterre. As a member of the family Hexanchidae, it has more close relatives in the fossil record than living relatives. The related living species include the dogfish, the Greenland shark, and other six- and seven-gilled sharks. Some of the shark's relatives date back 200 m ...

Squatina Aculeata
The sawback angelshark (''Squatina aculeata'') is an angelshark of the family (biology), family Squatinidae It is one of rarest species of sharks known to date, and one of the three species of angelsharks that inhabits the Mediterranean. The Sawback angelshark lives in sandy and muddy bottoms of the ocean at depths of 30-500m. Measurements Their size at birth ranges from 30 to 35 cm. As adults, female measurements range from 137 to 143 cm, while males range from 120 to 122 cm. Their relative weight based on the size of the shark for males is between 12.7 kg and 24.0 kg. In females, they weigh anywhere from 22 to 32 kg. The females grow to be larger than the males because they need to be able to carry and support their young. Development The development of the males was measured in three stages, juvenile, subadult and adult. The juvenile males had short and flexible claspers and the testes were membranous and barely developed. The subadult males sho ...

Squalus Uyato
The little gulper shark (''Centrophorus uyato'') is a small, deepwater dogfish of the family Centrophoridae. Physical characteristics The little gulper shark has no anal fin, two dorsal fins with spines, slightly humped back before the first dorsal fin, darker areas of coloration above gills and on dorsal fins, long free rear tips on pectoral fins, and a notched caudal fin. Distribution The little gulper shark lives in the northern Gulf of Mexico, the eastern Atlantic from Spain south to the Cape of Good Hope, the Mediterranean west of Sicily, the western Indian Ocean around Mozambique, Arabian Sea and Bay of Bengal around India, and possibly Taiwan. Habits and habitat The little gulper is a common dogfish and lives near the bottom between 50 and 1,400 m. They are ovoviviparous with usually only one pup per litter.

Squalus Megalops
The shortnose spurdog (''Squalus megalops)'' also known as the piked spurdog is a small shark located primarily off the coast of Southern Australia and South Africa.Braccini, J. M., et al. “Embryo Development and MaternalâEmbryo Nutritional Relationships of Piked Spurdog (Squalus Megalops).” ''Marine Biology'', vol. 150, no. 4, 2006, pp. 727–737., doi:10.1007/s00227-006-0393-2. The shortnose spurdog's size is dependent on the sex of the animal. The female shortnose spurdog is consistently larger than the male shortnose spurdog and will typically measure out to about 56.41 cm (1.85 ft) while the male shortnose spurdog will typically only measure out to about 44.36 cm in length (1.46 ft) which means the female shortnose spurdog is over 10 cm longer than the male shortnose spurdog.Marouani, Sondes, et al. “First Data on the Age, Growth and Sexual Maturity of the Piked Spurdog, Squalus Megalops (Chondrichthyes: Squalidae), in the ...

Squalus Acanthias
The spiny dogfish (''Squalus acanthias''), spurdog, mud shark, or piked dogfish is one of the best known species of the Squalidae (dogfish) family of sharks, which is part of the Squaliformes order. While these common names may apply to several species, ''Squalus acanthias'' is distinguished by two spines (one anterior to each dorsal fin) and no anal fin. It lives in shallow waters and further offshore in most parts of the world, especially in temperate waters. Those in the northern Pacific Ocean were reevaluated in 2010 and found to constitute a separate species, now called the Pacific spiny dogfish (''Squalus suckleyi''). Description and behaviour The spiny dogfish has dorsal fins, no anal fin, and white spots along its back. The caudal fin has asymmetrical lobes, forming a heterocercal tail. The species name ''acanthias'' refers to the shark's two spines. These are used defensively. If captured, the shark can arch its back to pierce its captor with spines near the dorsal fi ...

Somniosus Rostratus
The little sleeper shark (''Somniosus rostratus'') is a small sleeper shark of the family Somniosidae found in the northeast Atlantic, western Mediterranean, and western Pacific around New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count ..., at depths between 200 and 1,000 m. Its length is up to 1.43 m. Distribution This species is rarely encountered. It has in the northeast Atlantic and western Mediterranean. It has also been found in Israel and Cuba. Habitat Although currently the species has been found in water at depths of 180-2200m, it is possible that it may range deeper. It is a bathydemersal species found above sandy mud substrate on the outer continental shelves and on the upper slopes. Ecology Reproduction and Growth ''S. rostratus'' reaches a maximu ...

Centroscymnus Coelolepis
The Portuguese dogfish (''Centroscymnus coelolepis'') or Portuguese shark, is a species of sleeper shark of the family Somniosidae. This globally distributed species has been reported down to a depth of , making it the deepest-living shark known. It inhabits lower continental slopes and abyssal plains, usually staying near the bottom. Stocky and dark brown in color, the Portuguese dogfish can be distinguished from similar-looking species (such as the kitefin shark, ''Dalatias licha'') by the small spines in front of its dorsal fins. Its dermal denticles are also unusual, resembling the scales of a bony fish. This species typically reaches in length; sharks in the Mediterranean Sea are much smaller and have distinct depth and food preferences. Relatively common, the Portuguese dogfish is an active hunter capable of tackling fast, large prey. It feeds mainly on cephalopods and fishes, though it also consumes invertebrates and cetacean carrion. This shark has acute vision optimized ...

Oxynotus Centrina
The angular roughshark (''Oxynotus centrina'') is a rough shark of the family Oxynotidae. Taxonomy Biologist Carl Linnaeus described the angular roughshark, ''O. centrina'', in 1758. This name was later finalized and accepted by the scientific community as the official name for the species in 1976. Description At birth, they are less than and they mature at about . Most records are of individuals less than , but they can reach about . Their litter size is seven or eight pups off Angola to 23 in the Mediterranean. They have ridges over their eyes that expand into large, rounded knobs, which are covered with enlarged denticles – these are absent in other species of rough sharks. They possess very large spiracles that are vertically elongated, being almost as high as the length of their eyes. Their first dorsal spine is oriented slightly forward. They feed on worms, crustaceans, and mollusks.Compagno, L., Dando, M. and Fowler, S. ''Sharks of the World''. Princeton Field ...

Etmopterus Spinax
The velvet belly lanternshark (or simply velvet belly) (''Etmopterus spinax'') is a species of dogfish shark in the family Etmopteridae. One of the most common deepwater sharks in the northeastern Atlantic Ocean, the velvet belly is found from Iceland and Norway to Gabon and South Africa at a depth of . A small shark generally no more than long, the velvet belly is so named because its black underside is abruptly distinct from the brown coloration on the rest of its body. The body of this species is fairly stout, with a moderately long snout and tail, and very small gill slits. Like other lanternsharks, the velvet belly is bioluminescent, with light-emitting photophores forming a species-specific pattern over its flanks and abdomen. The ventral photophores are thought to function in counter-illumination, which camouflages the shark against predators and prey. The bioluminescent flank markings may play a role in intraspecific communication. Young velvet bellies feed mainly on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dalatias Licha
The kitefin shark or seal shark (''Dalatias licha'') is a species of squaliform shark in the family Dalatiidae, and the type species in its genus. It is found sporadically around the world, usually close to the sea floor at depths of . With a sizable oil-filled liver to maintain neutral buoyancy, this shark is able to cruise slowly through the water while expending little energy. The kitefin shark, the largest luminous vertebrate on record, has a slender body with a very short, blunt snout, large eyes, and thick lips. Its teeth are highly differentiated between the upper and lower jaws, with the upper teeth small and narrow and the lower teeth large, triangular, and serrated. Its typical length is , though examples as long as have been encountered. Armed with large teeth and a strong bite, the kitefin shark is a powerful, solitary predator that takes many different types of prey, ranging from bony fishes, sharks and rays, to cephalopods, crustaceans, polychaete worms ...
