Water or land? Doesn't matter

Though brilliant swimmers, river otters are as comfortable on land as they are in the water. They can walk and run easily on land, even in vegetation, and are known to slide on slippery surfaces like ice and mud as a speedy, easy way of getting from one place to another. Over land and water, they can travel as much as 26 miles in a single day when necessary, though they more often travel only a couple miles in one day.
