Overview: John Stoneman is the guest of the Monterey Aquarium in a study of the West Coast kelp forests and the special marine animals that live in and around them. Observations are made on the playful sea lions of the areas and the sea otter, which has learned how to use a tool, in the form of a rock, to break open its favorite food, the abalone. Stoneman's team also travels to British Columbia to continue their studies, this time on wolf eels and octopus.
