Spotted something wrong?

The frilled shark, or frill shark, is one of the two existing shark species in the family Chlamydoselachidae, with a wide but patchy distribution in the Atlantic and Pacific Oceans. This uncommon species is found on the outer continental shelf and the upper part of the continental slope, usually close to the bottom, although there is evidence of movements into shallower water. It has been caught at a depth of 1,570 m, while in Suruga Bay, Japan, it is commoner at depths of 50-200 m.

Fun facts

  • GeneralConsidered a living fossil; it has 300 three-pointed teeth in 25 rows and a snake-like body.
  • Its gestation can last three and a half years, the longest documented of any vertebrate: longer than an elephant, a whale or any other known animal.
  • It has three hundred teeth with three points each, curved towards the inside of the mouth and set in twenty-five rows: a trap that soft prey such as a squid cannot escape.
  • It is a living fossil whose appearance has barely changed in tens of millions of years, and its snake-like body has fed speculation about historical sightings of sea serpents.
