Otters have short, but powerful, legs. When
they are travelling on ice with just a light snow cover,
they will often kick-off and take long glides on their bellies-
not unlike kicksledding! I have seen parallel tracks, so
they must also do this as a group activity. But I've
never seen them in action.

This is the Canadian species, LONTRA CANADENSIS, but
I have also seen photos of the European otter, LUTRA LUTRA,
doing the same thing, for example from Sweden:
