Panning shot of tide moving across an Australian beach. Underwater shot of coral formations of the Barrier Reef. The American narrator describes the beautiful colours of the coral as the camera moves across scenes of coral which just pokes above the water.
Dozens of tiny crabs are seen (Soldier Crabs?) "they are always in a hurry" says the narrator, "even if they have no place to go."
Loggerhead and Green Turtles are seen making their way up the beach.
High angle shot of local Aborigine people digging in the sand for turtle's eggs. Narrator states: "The blacks hunt for these eggs, locating them by following the tracks left on the sand and sounding in likely spots with long sticks. Various shots of the local people gathering eggs. C/U of a nest - they hold on average two hundred eggs. A man takes eggs out of the nest - he piles them up in a bucket.
