Coral reefs, which comprise only about 0.5 per cent of the ocean floor, are complex three-dimensional structures built up over thousands of years as a result of the deposition of calcium carbonate skeletons of the reef building coral species. These reefs are often referred to as the "rainforest of the sea".
