Step 1 : Introduction to the question "7. What member of the weasel family is an excellent swimmer, playful, enjoys sliding down river banks in the winter, and feeds on fish, crayfish, muskrats, frogs, snakes and waterfowl?"
...1. Wolverine 2. Marten 3. River otter 4. Fisher River otters are well-adapted to their semi-aquatic environment, having a sleek body with a thick layer of fat beneath the skin. They live close to water and may even live in abandoned beaver lodges. They may be shy or very sociable, and they may live alone or in small family or bachelor groups. Otters are a real treat to watch in the wild! (While all these are members of the weasel family, only the otter is playful and water-loving.)
