What eats a giant otter?
Adult Giant Otters have no serious natural enemies, beyond human beings and possible and occasional predation by the Jaguar, Cougar, and anacondas. Cubs are more vulnerable, and may be taken by the Black Caiman and other large predators, although adults are constantly mindful of stray young. The Spectacled Caiman is another potential competitor. When in the water, the Giant Otter faces danger from animals that are not strictly preying upon it: the Electric eel and stingrays are potentially deadly if stumbled upon, and piranha may be capable of at least taking bites out of a Giant Otter, as evidenced by scarring on individuals.
