Shark's Tongue

A SHARK'S TONGUE
A shark's tongue is called a basihyal. A basihyal is a small, thick, relatively immovable piece of cartilage that is found on the floor of the mouth of sharks and fishes. The basihyal seems to be useless for most sharks, except for the cookiecutter sharks, who use it (along with very sharp teeth and suction) to rip "flesh-cookies" out of their prey (Shirai and Nakaya, 1992).
