River otters are built for water. They are strong swimmers with a coat that gets sleek when wet. This female river otter was sleeping on a log next to Trout Lake in Yellowstone National Park. She slept for quite a while there. When she woke up she stretched her legs and spread her toes showing the webbing that helps her swim through the water.
