6. The tiger shark is often found close to the coast, in mainly tropical and sub-tropical waters worldwide, though they can reside in temperate waters. Tiger sharks are among the largest predatory sharks after the great white. The shark’s behavior is primarily nomadic but is guided by warmer currents and it stays closer to the equator throughout the colder months. The shark tends to stay in deep waters that line reefs but does move into channels to pursue prey in shallower waters. This shark has been recorded down to a depth of 900 meters (3,000 ft) but is also known to move into shallow water that is normally too shallow for a species of its size.

In the southern hemisphere mating takes place in November or December or early January.

Litters range from 10 to 80 pups. A newborn is generally 51 centimeters to 76 centimeters long. It is unknown how long tiger sharks live but they can live longer than 12 years.
