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.
