Houtman Abrolhos australis"), are common between April and October, when the whales are migrating. Other marine mammals sometimes sighted at the islands include pygmy Bryde's whale ("Balaenoptera edeni"), orca ("Orcinus orca"), bottlenose dolphin ("Tursiops aduncus"), common dolphin ("Delphinus delphis"), and striped dolphin ("Stenella coeruleoalba"). The green turtle ("Chelonia mydas") and the loggerhead turtle ("Caretta caretta") both live in the waters off the Houtman Abrolhos, albeit in low numbers. Neither species breeds in the area, as water temperatures are too low. The Houtman Abrolhos is unusual in having a luxuriant and diverse living coral reef at such a high latitude. 194 species in
Deep sea creature extreme difference in pressure between the sea floor and the surface makes the creature's survival on the surface near impossible; this makes in-depth research difficult because most useful information can only be found while the creatures are alive. Recent developments have allowed scientists to look at these creatures more closely, and for a longer time. A marine biologist, Jeffery Drazen, has explored a solution, a pressurized fish trap. This captures a deep-water creature, and adjusts its internal pressure slowly to surface level as the creature is brought to the surface, in the hope that the creature can adjust. Another scientific
