A film series in which the famous underwater explorer takes his oceanographic vessel Calypso on a voyage of adventure and scientific discovery.

Sometimes called elephant seal, this huge creature was once hunted to the point of extinction. Now colonies survive under protection, including one at Guadalupe Island, a hundred miles from Baja California. There, Cousteau and his men make an intimate film study of the sea elephants, both on land and underwater, and discover that their lives are still full of hazards.
