A group of River Otters out of the water is called romp. The Otter in the water in this image is considered a raft. Romp is the perfect name for these lively, charismatic, playful weasels. They don’t hold still for more than a few seconds. They romp across the snow covered ice over the river, then suddenly disappear into a hole in the ice, emerging a minute or so later in another spot. They stay close together, snuggling and cavorting. What fun it was to watch them in Yellowstone National Park last week.
