List of corals of the Houtman Abrolhos
The marine waters of the Houtman Abrolhos, an island chain off the coast of Western Australia, have been recorded as containing 194 species of coral in 50 genera. This is a surprisingly high coral diversity, considering the high latitude of the reef, and the relatively low diversity of other biota. This is a list of corals of the Houtman Abrolhos:
