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:
Hans Lollik Island
The most common cetacean species to move through the waters of the greater Hans Lollik area include bottlenose dolphins ("'Tursiops truncatus") and humpback whales ("Megaptera novaeangliae"). Some pilot whales ("Globicephala melaena") may also occur in the area. The presence of humpback whales is seasonal, with peak migrations occurring during January through March. In addition to reef fish, schooling fish have been evaluated in the area around GHL and Litte Hans Lollik. Fish abundance is greatest in the offshore area of the east coast fringing reef and in the deep-water areas off the northwest corner of GHL. Three sea turtle species occur around the island, the hawksbill turtle, green turtle, and leatherback turtle..
