What the tiger shark eat?

Answer 1

anything it finds. but it always eats fish, squid, seabirds, sea mammals, other sharks, and turtles

Answer 2

The Great White shark or the bull shark is the only sharks that can and will eat the Tiger shark. However, it is known that Killer whales can and will kill the Great white. So if the Killer whales eat the Great white shark, what makes us think that the Killer whale wouldn't attack the Tiger shark?

Most of the time, it's not by coincidence that this happens, it's because the shark is in the wrong place at the wrong time. These predators don't go out of their way to hunt these predators. If these predators find these animals, well, you get the hint.
