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:
Abrolhos Marine National Park
Ilha Guarita and Ilha Sueste are home to many seabirds. 
Frigate birds nest on the steep sides of Ilha Redonda, which is visited by loggerhead turtles for spawning in the summer.
Diving along the reefs and the Rosalinda shipwreck is allowed, and humpback whales may be observed from boats.
Since 2003 the park has been an outpost of the Atlantic Forest Biosphere Reserve (RBMA: Reserva de Biosfera da Mata Atlântica).
In 2010 it was recognized as a Ramsar Site.
