12 Most Bizarre & Frightening Deep Sea Creatures
The frilled shark, Chlamydoselachus anguineus, is a species of deep-sea shark in the family Chlamydoselachidae, regarded as a "living fossil". It was long thought to be the only member of its family, until in 2009 frilled sharks off southern Africa were described as a separate species, C. africana. These species are very different from the other hexanchiform sharks, and it has recently been proposed that the two frilled sharks should be given their own order, Chlamydoselachiformes. Additional extinct types are known from fossil teeth. The frilled shark was thought to be extinct itself; it was only discovered alive in Japanese waters in the 19th century. On January 21, 2007, a specimen was found alive off the coast of Japan near the Awashima Marine Park in Shizuoka, southwest of Tokyo. The shark was captured but was not adapted to live in the warm, shallow water that it was moved to. The specimen died soon after capture.
