Tiger shark

Galeocerdo cuvier

Also calledTintorera (Spanish) · Itachizame (Japanese) · Niuhi (Hawaiian, man-eating shark) · Requin-tigre (French) · Papa (Swahili, shark)

A large, striped generalist predator of warm coasts, famous for eating almost anything, from sea turtles to license plates. Its saw-edged teeth can cut through turtle shell.

The tiger shark is a species of ground shark, and the only extant member of the genus Galeocerdo and family Galeocerdonidae. It is a large predator, with females capable of attaining a length of over 5 m. Populations are found in many tropical and temperate waters, especially around central Pacific islands. Its name derives from the dark stripes down its body, which resemble a tiger's pattern and fade as the shark matures. Wikipedia
