The giant otter (Pteronura brasiliensis), known through much of its range as the 'river wolf', is one of South America's top carnivores and is the largest of the otter species in terms of total length. The muscular, sinuous body is covered with velvety, brown fur, which is dense and water-repellent. A patch of cream colouring is present on the throat and chin, the pattern of which is unique to each individual from birth. The giant otter has short legs and large webbed feet which, along with the wing-like tail, allow the otter to move quickly through the water. The movement of prey is detected by the large eyes and sensitive whiskers.
