The Great Barrier Reef, located off the coast of Australia, is a diverse ecosystem composed of thousands of individual reefs. It is home to a vast array of marine species, including 1,500 species of fish, 400 species of coral, and 4,000 species of mollusks. Corals are the building blocks of the reef, with stony corals creating underwater structures. The reef supports a wide range of marine life, including clownfish, manta rays, dugongs, Maori wrasse, and great white sharks. However, the reef faces threats such as climate change, pollution, and overfishing, and conservation efforts are underway to protect it. Visitors can scuba dive or snorkel in the reef and contribute to its conservation through sustainable practices.
