(Galeocerdo cuvier)
The tiger shark (Galeocerdo cuvier) is a species of requiem shark and the only extant member of the genus Galeocerdo.It is a large macropredator,capable of attaining a length over 5 m (16 ft 5 in).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 but fade as the shark matures.The tiger shark is a solitary,mostly nocturnal hunter.It is notable for having the widest food spectrum of all sharks,with a range of prey that includes crustaceans,fish,seals,birds,squid,turtles,sea snakes,dolphins,and even other smaller sharks.It also has a reputation as a "garbage eater",consuming a variety of inedible,man-made objects that linger in its stomach.Though apex predators,tiger sharks are sometimes taken by groups of killer whales.It is considered a near threatened species due to finning and fishing by humans.The tiger shark is second only to the great white in recorded attacks on humans.
