The river otter (Lutra canadensis) is a dark brown mammal with a long slender body and short legs. Its rudder-like tail and webbed feet allow for rapid movement under water. Although aquatic, it runs well on land and may travel several miles over land to reach another body of water. It feeds mostly on fish, but also eats crustaceans, mollusks and small land animals such as mice and reptiles. Intelligent and playful, river otters are active in early morning and evening hours.
They are typically found in freshwater areas such as river banks, ponds and swamps throughout northern and eastern North America.
