Sand Tiger Sharks
The sand tiger shark is a large, slow-moving shark notable for its jagged teeth and menacing appearance. This shark looks fierce as it slowly swims with its mouth open and needle-like teeth exposed. Despite this, it is a relatively placid shark that has rarely been implicated in unprovoked attacks on people. It is found living close to the shorelines and sandy beaches of North America - hence the name sand tiger shark. The sand tiger shark prefers to hunt close to shore, and groups have been observed hunting large schools of fish. Its diet consists of small bony fish, stingrays, crustaceans and small sharks. It can adjust its buoyancy by gulping a mouthful of air and storing it in its stomach. It is also one of the few large sharks that will occasionally sit still on the bottom of the ocean.
