Owen the otter calls the north Pacific Ocean his home and is a marine mammal. He is one of the few mammals that can use tools, which he utilizes to break open his food. Typically sea otters dive quickly down to the sea floor to collect sea urchins, clams, mussels, abalone, snails, crustaceans, and fish. They don't have any blubber but they keep warm with their fur which is exceptionally thick.
