The frilled shark (Chlamydoselachus anguineus) is a rarely seen prehistoric, deep-water shark which has a long, slim, snake-like body but quite looks like eel because it lacks in fins too and has its gills around its throats.
Frilled sharks have been living in the deep ocean for 80 million years so they are often called ‘living fossils’.
The frilled shark has distinct 300 pin-shaped, backwards-facing teeth, which it uses to grab and kill prey, including fish, squid and other sharks.
