Cool Fact: Although it has hundreds of small teeth, the basking shark does not use them when feeding; instead, it usually swims with its mouth open and catches whatever plankton is filtered through.
The Frilled Shark is a deep-water shark that sports many “primitive” features, leading it to be dubbed a living fossil. Its name comes from the frilled appearance of its six pairs of gill slits. Visible are its approximately 300 teeth, with notable needle-like cusps and cusplets, suited for feeding on squid. Unlike most sharks, it is unique in having a long, slender, eel-like body, and unusual front-facing jaws, as opposed to the underslung jaws of most shark species.
Fun fact: Some of these sharks are thought to be over 400 years old. It is thought that the young do not reach sexual maturity until 150 years old. Check out wikipedia here for more information.
