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:
Pigeon Island (Houtman Abrolhos)
Pigeon Island is roughly triangular in shape, with a short side on the south west, and two long sides coming together at a point in the north east. The island is covered with infrastructure, with a high density of huts covering the entire island, right down to the water line; in total there are 54 camps, a school and a pub. There are also around 20 jetties, mainly along the northwest side, as this is the only direction from which the island may be approached by boat. The island is surrounded by reef to the south and east, but a passage known as Pigeon Island Anchorage runs along the northwest side.
