Otters are carnivores and love to find an eel for lunch. Otters have such thick, waterproof fur, with up to a million hairs per square inch! Their webbed feet and strong tail make them a successful predator and at the top of the food chain. They have adapted to life on land and in the water. They have webbed feet and the ability to shut their noses and ears underwater. Otters like to play. So otters have two coats of fur.
