The Great Barrier Reef

As the largest living structure on the planet, the Great Barrier Reef is incredibly rich and diverse.

Stretching 2300 kilometres, this natural icon is so large it can even be seen from outer space.

While it’s known mostly for its large maze of colourful reefs, its intricate architecture also provides a home for a huge number of animals and plants.

Some of these, such as turtles and crocodiles, have been around since prehistoric times and have changed little over the millennia. 

The breathtaking array of marine creatures includes 600 types of soft and hard corals, more than 100 species of jellyfish, 3000 varieties of molluscs, 500 species of worms, 1625 types of fish, 133 varieties of sharks and rays, and more than 30 species of whales and dolphins.
