A: Hatchlings and young juvenile sea turtles have many natural threats, both on land and at sea. These include fire ants, crabs, lizards, birds, dogs, raccoons, wild pigs, coyotes, dolphins, and many species of carnivorous fish such as snapper, grouper, and barracuda.
For the few who make it to adulthood, adult sea turtles do not have many natural predators. However, large sharks such as the Tiger Shark can sometimes snap at turtles, although they often only take a bite from a flipper or part of the shell. Killer Whales are also known to sometimes prey on Leatherback Sea Turtles. On land, adult female turtles that nest in the Caribbean and Central America may be attacked by a jaguar or wild boar, but this is rare.
