Characteristics and Behavior:

The Northern River Otter is a semi-aquatic mammal that is part of the weasel family. It has a long, sleek body with short legs and webbed feet that make it an excellent swimmer. The otter's fur is thick and waterproof, usually brown in color with a lighter underbelly, which helps it stay warm in the water. They have keen senses and can hold their breath for up to 8 minutes underwater. Northern River Otters are social animals and are often found living in family groups of up to 12 individuals. They are opportunistic feeders, and their diet consists of fish, crustaceans, mollusks, and small mammals.
