query: How many species live in The Houtman Abrolhos reef?
passage: Houtman Abrolhos
The Houtman Abrolhos is unusual in having a luxuriant and diverse living coral reef at such a high latitude. 194 species in 50 genera have been recorded there,[60] all but two of which are tropical. This is a surprisingly high coral diversity, considering the high latitude of the reef, and the relatively low diversity of other biota.[60] For a full list, see list of corals of the Houtman Abrolhos.
