Tiger sharks are carnivorous and eat mollusks, birds, snakes, crustaceans, sea turtles, dugongs, and even dead or injured whales.
The diet of tiger sharks includes mollusks, birds, snakes, crustaceans, sea turtles, and dugongs (Dugong dugon). Tiger sharks also often scavenge dead or injured whales.
As top predators in their ecosystem, it is possible that tiger sharks control populations of prey species, although this has not been verified.
