The tiger shark, Galeocerdo cuvier, one of the largest sharks, is the only member of the genus Galeocerdo. This shark is a solitary hunter, usually hunting at night. Its name is derived from the dark stripes down its body, which fade as the shark matures.

The tiger shark is a dangerous predator, known for eating a wide variety of items. Its usual diet consists of fish, seals, birds, smaller sharks, squid and turtles. It has sometimes been found with detritus such as license plates or pieces of old tires in its digestive tract. It is notorious for attacks on swimmers, divers and surfers in Hawaii; and is often referred to as the "bane of Hawaiian surfers" and "the wastebasket of the sea".

The tiger shark is second only to the great white in number of recorded human fatalities and is considered, along with the great white, bull shark and the oceanic whitetip shark to be one of the sharks most dangerous to humans.

This shark is known to be aggressive. The ability to pick up low-frequency pressure waves enables the shark to advance towards an animal with confidence, even in the environment of murky water where it is often found. The shark is known to circle its prey and even study it by prodding it with its snout. When attacking the shark devours all of its prey. Because of its aggressive nature of feeding, it is common to find a variety of foreign objects inside the digestive tract of a tiger shark. Some examples of more odd items would be automobile number plates as well as petroleum cans, baseballs, and tires.

Hmmm...what about hockey pucks?
