While in the water they paddle with their front feet, and use the hind feet as rudders. They can swim at a speeds of 4-6 mph and paddle non-stop for 100 miles. Have been seen swimming several hundred miles from the nearest ice or land. While swimming, they keep their eyes open, their nostrils shut and their ears flattened to their heads.
