o The frilled shark, Chlamydoselachus anguineus, is a species of deep-sea shark in the family Chlamydoselachidae, regarded as a "living fossil"
o These species are very different from the other hexanchiform sharks
o The frilled shark was thought to be extinct itself; it was only discovered alive in Japanese waters in the 19th century.
o On January 21, 2007, a specimen was found alive off the coast of Japan near the Awashima Marine Park in Shizuoka, southwest of Tokyo.
o 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.
