River otters are in their element in Yellowstone’s early winter. They avoid a hungry coyote with their excellent swimming skills, but soon the river will freeze.

This is a North American River Otter on the ice on Superior Bay which is at the end of the St. Louis River and along Park Point which is the world's largest fresh water sand bar - located at the western most end of Lake Superior - the world's largest freshwater lake. You can tell that this otter fishes for a living. The surprise in the video is seeing him come up with two fish on his second dive through the ice.
