River otters are often times mistaken for sea otters, but why? River otters do live in and around both fresh and salt water, however there are easy ways to identify the two species apart. First, river otters are commonly seen moving in and out of the water and are able to easily move around on land, versus sea otters that spend almost their entire life in water and are clumsy on land. Second, when in the water river otters commonly swim belly down, versus sea otters who swim belly up. Third, river otters are much smaller than their cousin the sea otter. Lastly, the paws of river otters and sea otters are webbed but the paws of a river otter are more circular shaped to aid in land locomotion versus seas otters that have webbing all the way to the toes to aid in water locomotion.
