The giant otter, sometimes called "the river wolves", is the largest otter in the world. They belong to the weasel family. The giant otter can grow up to 2m in length and 32 kg. It has sharp teeth. It possesses water-sensing whiskers and strong webbed forehands for convenience in swimming. Other than fish, their diet includes anaconda snakes and even caiman. For fish, it eats all the fish they have caught, not even letting go the bones. Usually, only one pair of otters will mate in a pack of 4 to 10. The pair will give birth to about 4 young.

They existence of the giant otter has been threatened by man, who hunts them for their fur. From 1946 to 1973, a total of 44,000 otter skins were exported from Peru and Brazil. A lw was passed in 1974 to protect the species.
