Great Barrier Reef with David AttenboroughEpisodes Guide

David heads beneath the surface at night-time in a state-of-the-art Triton submersible. Here he meets some of the tiny coral animals that have bult the reef and have turned it into a underwater wonderland.

David learns more about the creatures that visit the reef every year, from birds to whales. He returns to the nesting site of the green sea turtle and marvels at manta ray cleaning stations.

David tries to understand what the next few decades hold for the remarkable community of animals that call the Reef home. He also looks at the work that is been done to save it.
