Anatomy: The tiger shark,like other sharks, have a ampullae of Lorenzini,which help the shark detect electric fields. Tiger shark teeth enable it to have its diet, as it can easily tear through bone and turtle shells.

Behavior: Tiger sharks are solitary animals. Tiger sharks are nomadic animals, meaning they will move place to place and never call just one area their home. They are also know to forage for prey along the coast.

Reproduction:Sharks begin to mate when the reach a certain length. The tiger shark is ready to mate at 7.5 feet for males, and 8.2 feet for females. They mate in the summer. Males will bite the female during mating and insert one clasper. The tiger shark is ovoviviparous, meaning the eggs develop and hatch in the mother. It takes 16 months for tiger shark offspring to develop. They will have litters of 10 to 80 pups, but they are on their own whan they are born.

Relationships with other animals: Tiger sharks scare almost every animal. Dolphins( Family Delpihindae) will hide at the sight of one. However few animals don't mind being with them. Remoras(family echeneidae) help the shark out, while parasites eat the sharks skin and blood. Humans use tiger sharks as food. Tiger shark's will attack Humans on rare occasions. The tiger shark is considered sacred in Hawaii.
