Coastal Waters
Tiger sharks tend to be found in coastal waters because various other conditions of their habitat are most often found in coastal waters. They are prevalent, for instance, throughout the South Pacific in waters not located near to any coast. The tiger shark prefers the environment near a reef. They eat a wide variety of sea life and bird life, and reefs are often thriving ecosystems with an abundance of various animal life.
Common Depths
Tiger sharks prefer the kinds of depths that can be found in the deeper waters that surround many reefs, although they can go significantly deeper and have been found as deep as 350 meters. Tiger sharks prefer shallower waters and hunt in harbors, inlets and various other shallow marine environments. Because of this tendency to be found in shallow areas, they come in to frequent contact with humans and are the second most deadly sharks to humans, behind only great white sharks.
Warm Waters
Tiger sharks tend to prefer warmer waters, often sticking to tropical areas. They have been known to wander as far north as the southern waters of Japan and as far south as the islands of New Zealand, when seasonal changes in water temperature permit. In colder months, they tend to stick closer to the equator where waters are generally warmer.
Worldwide Range
Tiger sharks are found throughout the world, on the coasts of every major continent, except Antarctica, as well as throughout the Southern Pacific Ocean and in some areas of the Mediterranean Sea. Despite being quite common and having such a large range, overfishing has adversely affected the tiger shark, and they are listed as a near-threatened species by the World Conservation Union.
