Catshark
Catsharks are ground sharks of the family Scyliorhinidae. They are the largest family of sharks with around 160 species placed in 17 genera. Although they are generally known as catsharks, some species can also be called dogfish due to previous naming. However, a dogfish may generally be distinguished from a catshark as catsharks lay eggs while dogfish have live young. Like most bottom feeders, catsharks feed on benthic invertebrates and smaller fish. They are not harmful to humans. The family is paraphyletic, containing several distinct lineages that do not form a monophyletic group. Genera The family includes 17 genera and over 150 species, making it the largest family of sharks. * '' Akheilos'' White, Fahmi & Weigmann, 2019 * ''Apristurus'' Garman, 1913 * ''Asymbolus'' Whitley, 1939 * ''Atelomycterus'' Garman, 1913 * ''Aulohalaelurus'' Fowler, 1934 * ''Bythaelurus'' Compagno, 1988 * ''Cephaloscyllium'' T.

Carcharhiniformes
Carcharhiniformes , the ground sharks, are the largest order of sharks, with over 270 species. They include a number of common types, such as catsharks, swellsharks, and the sandbar shark. Members of this order are characterized by the presence of a nictitating membrane over the eye, two dorsal fins, an anal fin, and five gill slits. The families in the order Carcharhiniformes are expected to be revised; recent DNA studies show that some of the conventional groups are not monophyletic. The oldest members of the order appeared during the Middle-Late Jurassic, which have teeth and bodyforms that are morphologically similar to living catsharks. Carchariniformes first underwent major diversification during the Late Cretaceous, initially as small-sized forms, before radiating into medium and large body sizes during the Cenozoic. Families According to FishBase, the nine families of ground sharks are: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galeus
''Galeus'' is a genus of catshark, belonging to the family Scyliorhinidae, commonly known as sawtail catsharks in reference to a distinctive saw-toothed crest of enlarged dermal denticles, found along the upper edges of their caudal fins. They are found in the Atlantic, the western and central Pacific, and the Gulf of California, inhabiting deep waters at or close to the sea floor. Members of this genus are rather small, slim sharks with firm bodies and thick, rough skin. Their heads are usually fairly long and pointed, and have large mouths with well-developed furrows at the corners. They have large pectoral and anal fins, and two similar dorsal fins placed well back. Many species are ornately patterned with dark saddles and/or blotches. Sawtail catsharks feed on various invertebrates and fishes, and may be either egg-laying or live-bearing. These harmless sharks are sometimes caught as bycatch but are of minimal commercial value.

Figaro (genus)
''Figaro'' is a genus of catshark, and part of the family Scyliorhinidae. Until 2008, ''Figaro'' was generally considered to be a subgenus of ''Galeus'' (sawtail catsharks). The two known species are found off Australia, inhabiting deep, offshore waters on or near the bottom. ''Figaro'' contains small, slender, firm-bodied sharks that bear distinctive crests of enlarged, spiny dermal denticles along the dorsal and ventral edges of their short caudal fins. The caudal peduncle is relatively long, such as that the anal and caudal fins are some distance apart. In adult males, the inner margins of the pelvic fins are fused together to form a subtle "apron" over the claspers. ''F. boardmani'' is a predator of fishes, crustaceans, and cephalopods, and is oviparous; less is known about the ''F. striatus''. Both are harmless and are of no economic importance. Taxonomy ''Figaro'' was coined as a subgenus of ''Pristiurus'' by Australian ichthyologist Gilbert Percy Whitley in a 192 ...

Cephaloscyllium
''Cephaloscyllium'' is a genus of catsharks, and part of the family Scyliorhinidae, commonly known as swellsharks because of their ability to inflate their bodies with water or air as a defense against predators. These sluggish, bottom-dwelling sharks are found widely in the tropical and temperate coastal waters of the Indian and Pacific Oceans. They have stocky, spindle-shaped bodies and short, broad, and flattened heads. The mouth is capacious, containing many small teeth and lacking furrows at the corners. The two dorsal fins are placed far back on the body, with the first much larger than the second. Different species have various color patterns of saddles, blotches, reticulations, and/or spots. The largest members of the genus can grow over in length. Swellsharks prey on a variety of fishes and invertebrates, and are oviparous, with females producing egg capsules in pairs. They are harmless and have been deemed of having no commercial value. Taxonomy The genus ''Cephalosc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cephalurus
The lollipop catshark (''Cephalurus cephalus'') is a little-known species of deep sea catshark, belonging to the family Scyliorhinidae, and the only described member of its genus. A diminutive, bottom-dwelling shark of the outer continental shelf and upper continental slope, this species can be readily identified by its tadpole-like shape with a greatly expanded, rounded head and narrow body. The large head houses expanded gills, which are thought to be an adaptation for hypoxic conditions. This shark preys on crustaceans and fishes. Reproduction is aplacental viviparous, with females retaining egg cases internally two at a time until they hatch. There is no fishery interest in this species. Taxonomy and phylogeny The lollipop catshark was originally described by American ichthyologist Charles Henry Gilbert as ''Catulus cephalus'', in the 1892 14th volume of ''Proceedings of the United States National Museum''. His description was based on a long adult male caught from a dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
