The Great Barrier Reef, which lies off the coast of Australia, is the world’s largest coral reef. It stretches 2010 kilometres along the north-east coast of Australia. Many kinds of corals grow here. Some pink, some orange, some bright blue and some yellow.
It is like a great underwater garden. Bright coloured fishes and plants live around the turquoise waters of the reef. The starfish are the reef’s most dangerous enemies and they cannot be destroyed.
