The Frill Shark has a long slender eel-like body and a large mouth. It lives in continental slope waters where it feeds in caves and crevices.
The Frill Shark can be recognised by its slender eel-like body, six pairs of gill slits, terminal mouth, three-pronged teeth, single dorsal fin, caudal fin without a lower lobe, and brown colour.
The jaws can be opened very wide. Little effort was required to open the mouth wide enough to take the photographs of the upper and lower jaws on this page.
The Frill Shark's teeth at the margins of the jaw are gradually replaced by those behind. The teeth have three long cusps with a tiny cusplet at the base of each "V" formed by the the large cusps.
Chlamydoselachus anguineus is the only living species in the Family Chlamydoselachidae.
It occurs in oceanic waters at depths from 120 m to 1500 m.
In Australia, the species has been caught from off New South Wales and Tasmania.

Feeding and diet
According to Last and Stevens (1994), the few stomach contents that have been examined included other elasmobranchs (sharks and rays). The species has been reported to feed in caves and crevices on the continental slope.
During mating, one clasper is inserted into the body of the female Frill Shark to facilitate sperm transfer.
