Chlamydoselachidae
''Chlamydoselachus'' is a genus of sharks and the sole extant member of the family Chlamydoselachidae, in the order Hexanchiformes. It contains two extant and several extinct species. The most widely known species still surviving is the frilled shark (''Chlamydoselachus anguineus''). It is known as a living fossil, along with ''Chlamydoselachus africana'', also known as the southern African frilled shark, which is only found along coastal areas of South Africa. The only two extant species of this genus are deep-sea creatures which are typically weakened in areas closer to the surface.

Hexanchiformes
The Hexanchiformes are the order consisting of the most primitive types of sharks, and numbering just seven extant species. Fossil sharks that were apparently very similar to modern sevengill species are known from Jurassic specimens. Hexanchiform sharks have only one dorsal fin, either six or seven gill slits, and no nictitating membrane in the eyes. Shark teeth similar to those modern hexanchids are known from Devonian deposits in Antarctica and Australia, as well as Permian deposits in Japan. If these are in fact hexanchids, this may be the only extant order of elasmobranchs to have survived after the Permian extinction (and by extension, the oldest extant order of elasmobranchs). The frilled sharks of the genus ''Chlamydoselachus'' are very different from the cow sharks, and have been proposed to be moved to a distinct order, Chlamydoselachiformes.

Frilled Shark
The frilled shark (''Chlamydoselachus anguineus'') and the southern African frilled shark (''Chlamydoselachus africana'') are the two extant species of shark in the family '' Chlamydoselachidae''. The frilled shark is considered a living fossil, because of its primitive, anguilliform (eel-like) physical traits, such as a dark-brown color, amphistyly (the articulation of the jaws to the cranium), and a –long body, which has dorsal, pelvic, and anal fins located towards the tail. The common name, ''frilled shark'', derives from the fringed appearance of the six pairs of gill slits at the shark's throat. The two species of frilled shark are distributed throughout regions of the Atlantic and the Pacific oceans, usually in the waters of the outer continental shelf and of the upper continental slope, where the sharks usually live near the ocean floor, near biologically productive areas of the ecosystem. To live on a diet of cephalopods, smaller sharks, and bony fish, the frilled s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern African Frilled Shark
The southern African frilled shark (''Chlamydoselachus africana'') is a species of shark in the family Chlamydoselachidae, described in 2009. It is found in the deep waters off southern Angola to southern Namibia. This species is difficult to distinguish from the better-known frilled shark (''C. anguineus''), but is smaller at maturity and differs in several proportional measurements including head length and mouth width. It seems to be a specialized predator of smaller sharks, using its flexible jaws and numerous needle-like, recurved teeth to capture and swallow them whole. Reproduction is presumably aplacental viviparous, as with the other member of its family. Taxonomy The frilled shark (''C. anguineus'') was long thought to be the only extant member of its genus and family. The existence of a second ''Chlamydoselachus'' species off southern Africa was first suspected from a specimen caught off Lüderitz, Namibia in February 1988, by the South African research ship FRS ''A ...
