Tiger sharks are aggressive predators, famous for eating just about anything they find or are able to capture.
They have been known to eat many different fishes and invertebrates, seabirds, sea turtles, some marine mammals, stingrays and other rays, smaller sharks, sea snakes, and scavenged dead animals, among other things.
Several tiger sharks have been known to eat garbage, including metal, plastic, wood, fishing gear, and other trash.
Though they are generalist predators, in some areas, tiger sharks likely specialize on certain highly available prey.
For example, in Hawaii, tiger sharks are known to regularly attack and eat green turtles and hawaiian monk seals near the nesting beaches for those two species.
Scientists often observe individuals with missing flippers that have been bitten off by a Tiger.
At other island groups, tiger sharks are known to congregate near seabird rookeries during the times when young birds are learning to fly (and often end up on the sea surface).
Finally, tiger sharks have been known to bite people, and their rather large size leads to occasional fatalities, particularly in areas where large numbers of people use the ocean, recreationally.
