The Giant Otter is a carnivorous mammal that lives in North- Central South America.

They live mostly in or along the Amazon River and the Pantanal.

Giant Otters are also called River Wolves or Water Dogs.

Males are 1.5 to 1.7ft long from head to tail and females are 1 to 1.5ft long, and their tails are about 70cm long.

Males are 26 to 32kg and females are 22 to 26kg in weight.
