In 2004, marine biologists first observed the frilled shark (Chlamydoselachus anguineus) at the depth of 873.55 m (2,866.0 ft), in its deep-water habitat at the Blake Plateau, off the southeastern coast of the U.S. [20] In 2007, a Japanese fisherman caught a 1.6 m (5.2 ft)–long female frilled shark at the surface of the ocean and delivered it ...
They are one of only two extant families in the order alongside the cow sharks in the family Hexanchidae, and the only members of the suborder Chlamydoselachoidei. [1] [2] They are now represented only by two extant species in the genus Chlamydoselachus: the frilled shark (C. anguineus) and the Southern African frilled shark (C. africana).
The largest species of the genus known to have existed is C. kamchaticus from the Early Eocene of Kamchatka, Russia, whose teeth are about twice the size of modern frilled shark teeth. It is one of the largest frilled sharks known to have existed, with estimated body length of 3.80 metres (12.5 ft). [4]
The frilled shark has about 300 needle-like teeth, which are spread out in 25 rows. Experts believe the species is about 80 million years old. They have a prehistoric look about them with a long ...
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 Africana (after which this species would eventually be named).
A giant shark that was known as a megalodon use to terrorize the underwater world. Although the enormous sharks didn't make the evolutionary cut, researchers believe they still had a big impact on ...

Previous best guesses estimated that the shark's demise happened about 1.5 million years back. Now researchers are saying it took place closer to two-and-a-half million years ago.
