The Great Barrier Reef is the home of many colourful and interesting sea creatures. More than 1500 species of fish live on the reef, including the Clownfish, Red Bass, Red-Throat Emperor, and several species of Snapper and Coral Trout. The Great Barrier Reef was named one of the Seven Natural Wonders of the World by CNN in 1997, and it’s no surprise, given its span, its diverse inhabitants, and its wonderful colors. Moreover, the reef is also a popular tourist destination for native Australians as well as travelers looking for the ultimate diving and snorkeling experience.
