The sea otter is a mammal that is closely related to badgers, skunks and mink. They have tough paws and hidden air pouches for oxygen which don't hold air very long. They also has good under -water vision for seeing and finding their food.
Sea otters live in the Northern Pacific Ocean in mostly Alaskan waters.
The sea otter eats mussels but the sea urchin and crabs appear to be prey also. Sea otters can dive 120 feet for food. The sea otter's predators are sharks, killer whales, and eagles because they will snatch baby Sea Otters.
