Tiger Shark Part 3The tiger shark, which generally hunts at night, has a reputation for eating anything it has access to, ignoring what nutritional value the prey may or may not hold. Apart from what is thought to be sporadic feeding, its most common foods include; common fish, squid, birds, seals, other sharks, and sea turtles. The shark has a number of features which make it a good hunter, such as excellent eyesight, which allows for access to murkier waters which can offer more varieties of prey and its acute sense of smell which enable it to react to faint traces of blood in its waters and is able to follow them to the source. The tiger shark`s ability to pick up on low-frequency pressure waves produced by the movements of swimming animals, for example the thrashing of an injured animal, enables the shark to find a variety of prey. The 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 unusual items are automobile number plates, petroleum cans, tires, and baseballs. For this reason, the Tiger Shark is often regarded as the ocean`s garbage can.
