Frilled Shark

Chlamydoselachus anguineus




Frilled sharks look really different to most of the sharks we are familiar with, and their long, snake-like appearance is thought to have inspired tales of huge sea serpents. It has a large blunt head and a very large mouth armed with lots of rows of sharp teeth. The shark uses these teeth to catch fish, squid and smaller sharks. Behind the head are 6 pairs of “frilly” gill slits, with the first pair going all the way around the neck to meet underneath. These gill slits have the appearance of ruffles or frills around its neck, and give the animal its name.

Fossil record suggests it belongs to a group of sharks that has been around for at least 95 million years! The frilled shark is also known as the lizard shark or scaffold shark.


Found in the Atlantic, Indian and Pacific Oceans - in the Eastern Atlantic found from Norway to South Africa.
