Alternative Name/s
Frill-gilled SharkIdentification
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.
