 The diet of the tiger shark is a highly variable; includes fish, other sharks, rays, marine mammals, marine turtles, birds, and sea snakes. Its coloration varies from bluish or greenish gray to black above and from light gray to dirty yellow or white below dark grey with vertical tiger-stripe markings; can fade or be obsolete in adults. They have many adaptations, one of them is their teeth are replaced throughout their life. Also they have sensitive smell receptors. They have eyes that adapt quickly to low light levels. They are known for the electroreceptor’s that detect electrical fields due to the presence of prey. Tiger sharks are named for the dark, vertical stripes found mainly on juveniles. As these sharks mature, the lines begin to fade and almost disappear. They can be recognized by its blunt head, serrated cocks-comb-shaped teeth and its coloration.
