River Otters

River otters are playful mammals that love the water. They are excellent swimmers and divers. River otters are known for sliding down muddy or snowy banks just for fun. They live near rivers, lakes, and streams across North America.

Born to Swim

River otters have sleek, waterproof fur and webbed feet. They can hold their breath for up to 8 minutes. Their powerful tails help them steer through the water. Otters can close their ears and nose when they dive underwater.

Playful Nature

River otters are some of the most playful animals in nature. They slide down hills, wrestle with each other, and play with rocks. Scientists think play helps young otters learn hunting skills. Otters eat fish, crayfish, frogs, and other water creatures.
