Marine mammals - dolphins, whales, seals - share a common, ancient heritage with man. Cousteau travels from the South Pacific to the Florida Keys, South Carolina and Argentina to understand their evolution and unique behavior. Among some remarkable footage: in South Carolina's salt marshes, we observe dolphins herding fish into shallow water and onto dry land - the dolphins actually leave the water - before scooping up the fish and eating them.
