Species

The Great Barrier Reef is the largest coral reef system in the world, supporting a wide variety of species. New species continue to be identified, adding to the diverse range of life found within this ecosystem. This biodiversity is important for the overall health of the Reef and its resilience, is critical to the Traditional Owners of the Reef, and contributes to the Reef’s natural heritage values and outstanding universal value. 

The Reef is home to many groups of species, such as corals, seagrasses, sea snakes, and bony fishes. Some species are known to be of conservation concern and are vulnerable to various impacts, notably climate change, water quality, and cumulative factors. Maintaining the health of species is essential to the Reef's resilience as a functioning ecosystem.
