Sea otters, members of the weasel family, live in the cold waters of the North Pacific Coast, from California up to Alaska. They live in groups called rafts and spend most of the day fishing and eating. Otters burn a huge amount of calories, so they eat up to 25% of their body weight a day to keep their cold-water, aquatic lifestyle going. Their thick, water-repelling fur, the densest of any mammal, is so effective their skin never actually gets wet. That allows them to comfortably spend almost their entire lives in the water. Courtesy:
