Sea Otters are on 2 different episodes, and are #8 on Divers, and #10 on Gadgets. They can spend up to 6 minutes underwater, using their fur coat as a dry suit. They spend hours underwater collecting shellfish from the seafloor, and can stay down for long periods of time thanks to their lungs. They use stones to break shellfish to eat them, some even carry their favorite stones. Young pups have to learn by watching their mother, and take up to 8 months to learn how to use them.
