The North American River Otter is a semi-aquatic mammal that is found in North America.
They are the smallest otters in the world and have a long body, short legs, and a big head. They have thick brown fur that keeps them warm in the water and a furry tail that is used for swimming.
North American River Otters live near rivers, lakes, and marshes where they can find food. They eat fish, frogs, crayfish, and other small animals. They are also known to eat plants and fruits. North American River Otters like to play and swim in the water, and they use their furry tail as a rudder when swimming.
These otters are very playful and social animals. They often swim together in groups, and they will play with each other by chasing and jumping on one another. They are also known to be very curious and will often check out new things in their environment.
