River otters (Lontra canandensis) are active and entertaining, known for gregarious sociability within their family groups.
River otters eat fish, crawfish, frogs and snakes in the wild.
River otters live in rivers and ponds throughout North America.
After some concern about population decline in the 1970s, reintroduction programs began in an effort to stabilize the population. River otters are listed as a species of least concern, although habitat destruction, pollution and other factors continue to imperil the species.
River otters are part of the weasel family. In some parts of the world, otters have been trained to catch fish for fishermen.
