A semi-aquatic, playful predator with a streamlined muscular body, glossy brown fur, short legs, webbed toes, long whiskers, and a long muscular tail. River Otters weigh between 6 and 31 lbs. They are powerful swimmers that can travel quickly on land and are often seen sliding down river banks into the water. Otters mainly eat fish and often swim in circles, creating a whirlpool-like motion that brings fish to the top of the water. Otters have been over-hunted for their highly-prized fur. Although efforts have been made to protect them, otters remain an endangered species in many states.
Wetland
The North American river otter is found throughout North America, inhabiting inland waterways and coastal areas in Canada, the Pacific Northwest, the Atlantic states, and the Gulf of Mexico.
Common
Diurnal
Eat mainly aquatic organisms such as amphibians, fish, turtles, crayfish, crabs, and other invertebrates.
Northern Otter individuals live alone or in family groups, typically females and their young. They are known as playful animals, exhibiting behaviors such as mud/snow sliding, burrowing through the snow, and waterplay. Many "play" activities actually serve a purpose. Some are used to strengthen social bonds, to practice hunting techniques, and to scent mark. North American river otters get their boundless energy from their very high metabolism, which also requires them to eat a great deal during the day.
North American river otters are important predators of fish and aquatic invertebrates.
