The tiger shark is a solitary, mostly nocturnal hunter. Its diet includes a wide variety of prey, ranging from crustaceans, fish, seals, birds, squid, turtles, and sea snakes to dolphins and even other smaller sharks. The tiger shark is considered a near threatened species due to finning and fishing by humans.
While the tiger shark is considered to be one of the sharks most dangerous to humans, the attack rate is low according to researchers. The tiger is second on the list of number of recorded attacks on humans, with the great white shark being first. They often visit shallow reefs, harbors and canals, creating the potential for encounter with humans.
