North American RIver Otters Lontra canadensis have a voracious diet thanks to their high metabolism. These playful mammals eat variety of aquatic wildlife, such as fish, crayfish, crabs, frogs, birds’ eggs, birds and other reptiles such as turtles.They can thrive in any water habitat, such as ponds, marshes, lakes, rivers, estuaries and marshes—in cold, warm or even high elevation areas—as long as the habitat provides adequate food. River otter dens are along the water in abandoned burrows or empty hollows. The dens have entrances underwater so they can be easily accessed from the water.

River otters are similar to sea otters in that they’re both a type of weasel with long slender bodies, have webbed feet for swimming, are excellent underwater hunters, and have two layers of fur to keep warm in cold water. The main differences between the two are in their size (sea otters are generally larger), their lifestyle (sea otters rarely leave the water and eat an exclusively marine diet), and their swimming style (sea otters float on their backs while river otters swim on their stomachs).

The North American River Otter is considered a species of Least Concern by the IUCN Red List, however in the past has been hunted extensively for their fur.
