Australia's Coral Wonderland

Shows microscopic views of the coral polyp which is responsible for the formation of the Great Barrier Reef. Underwater photography gives glimpses of an octopus, starfish, sea anemone, hermit crab, and many types of deep-sea fish. A sequence follows a giant turtle inland, where she digs a nest in which to lay her eggs. Baby turtles are then shown emerging from the eggs and going toward the sea.
