The river otter is a powerful swimmer more at home in the water than on land where it is subject to predation by coyotes, wolves, lynx and bobcats.

The river otter usually produces a litter of 2 to 3 offspring once a year. An otter family is a sight to behold when one is lucky enough to see them at play in their natural habitat.
