S01E01 Sharks
Captain Cousteau and his ship the Calypso visit the Red Sea, the Indian Ocean and the Gulf of Aden in order to study shark behaviour and to test methods of protecting shipwreck and air crash...
The divers travel inland to Peru's Lake Titicaca, testing experimental techniques for diving at high altitude for the first time. Deep in the lake they discover a unique species of frog whose lungs have atrophied like fish, they die when removed from the water. Cousteau's divers investigate the lake's legend of Inca treasure. The treasure proves to be illusory, but ancient pottery and a unique species of aquatic frog are found.
The intrepid undersea explorer and author circles the globe on his floating laboratory, Calypso, in this occasional series. A pioneer in marine study, the red-capped Frenchman introduced generations of landlubbers to the creatures and mysteries of the sea.
