Cookie-cutter shark

Cookie-Cutter Shark
Cookie-cutter Sharks live deep in the ocean, at depths of 3500 m. At night they come to the surface waters of the ocean to feed.

Physical Characters
Cookie-cutter Sharks have big triangular teeth in the lower jaw.

Cookie-cutter sharks are essentially a solitary species, coming together only to mate. They follow a diel cycle of movement, coming closer to the surface at night, when they are more likely to be caught in fishing nets.

Teeth and Diet: The cookie-cutter shark eats by taking round (cookiecutter-shaped) bites out of its victims with its long teeth and powerful jaws, mostly attacking large fish and whales (including dolphins).

The cookiecutter shark, Isistius brasiliensis (Quoy and Gaimard, 1824), aka cookie-cutter shark, smalltooth cookiecutter shark or cigar shark, is a small, deep-water shark named for the cookie-shaped wounds it leaves on larger fish and marine mammals.
