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 ...
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).
It contains two extant and four 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 ...
Frilled sharks, often called 'living fossils' are one of those lesser-known species -- and a man. Most shark reports concern the more common varieties, but there are more than 400 known species of ...
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 ...
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 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. However, genetic studies have found them to be each others' closest relatives, and they share certain derived features supporting them both being in the same order.
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.
