Giant River Otter

The largest member of the weasel family, the Giant River Otter grows over six feet long and can weigh over 80 pounds. It lives exclusively in the river systems of the Amazon, Orinoco and La Plata. These sleek, streamlined, aquatic mammals have short legs, semi-retractable claws, and nostrils and ears that close in the water. They flex their long bodies and propel themselves through the water with their webbed feet and powerful tails. The Giant River Otter has a very fast metabolism and is active all year long; its dense, waterproof fur keeps it warm.

The nocturnal Giant River Otters are very intelligent, charismatic, social animals that live in family groups typically centered around a dominant pair. They burrow into logs and river banks to create underground dens to rest in during the day, and will defend these territories aggressively. The carnivorous Giant River Otter primarily eats fish, supplementing with crustaceans, snakes, amphibians, insects, birds and small mammals.

Bald eagles, bears and coyotes prey on the Giant River Otter.

Increasing Their Survival Rate
The IUCN classifies Giant River Otters as endangered. Giant River Otters are hunted and poached extensively and therefore among the rarest otters in the world; it’s believed that only a few thousand remain in the wild. Other threats include habitat destruction and degradation. To learn more, visit the Giant Otter Project of The Frankfurt Zoological Society.
