Great Barrier Reef

The first film explores the complex structure of the coral reef itself and the wildlife that lives on it. So vast it is visible from space, the reef is actually built by tiny animals in partnership with microscopic plants. It is a place full of surprises that is always changing, responding to the rhythms of weather, tide, sun and moon.

The Great Barrier Reef as a whole covers an area larger than Great Britain, but amazingly only seven per cent of it is coral reef. The rest is a variety of interconnected habitats including the world's oldest jungle, hundreds of islands, mangrove swamps, mysterious deep-water gardens, vast sand flats and meadows of sea grass.

Australia’s Great Barrier Reef is vitally linked to the rest of the planet in many ways. Creatures travel for thousands of miles to visit, including tiger sharks, great whales, seabirds and the largest green turtle gathering on the planet. And as this nature documentary shows, weather patterns and climate change are likely to shape the future of the Great Barrier Reef and all its wildlife.
