Giant River Otter

Pteronura brasiliensis

Animals of All Regions Back
Giant river otters are the largest and most vocal (in terms of frequency and volume) of all otter species. Each otter has a uniquely-shaped white patch on the throat that can help to identify individuals. They also have full-webbing between the toes and a flattened wedge of a tail that serves as a rudder when swimming.  While under water, they have the ability to close their nostrils and ears. 

Giant river otters forms groups between 4 to 8 individuals, but can reach up to 20 members. Group members help to guard and mark home ranges. Males and females will mate for life, and pregnant females will give birth to their young in a burrow on land.
