Great Barrier Reef

Australia's Great Barrier Reef is one of the natural wonders of the world and the largest living structure on the planet; Monty Halls explores the complexity of the reef itself and the wildlife that lives on it.

Only seven percent of the Great Barrier Reef is coral and the remainder is a variety of interconnected habitats including the world's oldest jungle, hundreds of islands, mangrove swamps, deep water gardens, sand flats and sea grass.

Creatures travel thousands of miles to visit the reef and Pacific weather patterns are likely to further shape the terrain and wildlife.
