Welcome to the Home of the Pteronura brasiliensis!


This website will allow you to take a glimpse at the mesmerzing life of a river otter!


The Pteronura brasiliensis is more commonly known as the giant river otter, and it is currently an endangered species native to South America. 


The giant river otter is the largest of its family, growing to be almost 6 feet long and weighing up to 70 pounds! They can be found in freshwater locations such as rivers, ponds, lakes, and swamps, and they have very few predators. The giant river otter's food supply consists mainly of fish, although they occasionally snack on small snakes, alligators, and mollusks as well.







The Pteronura brasiliensis is a very social mammal. They typically live in groups of 5 to 8, consisting of a mating pair and several generations of offspring.  They hunt, travel, and communicate with each other, which is very uncommon among other species within their family.


The young are not able to do much until they are about two months old. They spend the first part of development underground in a den, and once they are about two months of age, they are usually able to walk on their own and learn how to swim. The young don't even open their eyes or mouths until they are about one month old and are not fully independent of their parents until nine months of age. Both the father and mother play a large role in raising their young.
