Solitary Islands Marine Park spp"), as well as sacred kingfishers ("Todiramphus sanctus"), are regularly seen in the estuaries. Around 30 species of marine mammals have been recorded in the region, including the Short-beaked common dolphin ("Delphinus delphis") and bottlenose dolphin ("Tursiops truncates") who are residents throughout the year. Of particular interest in the Marine Park and Reserve are those species listed as threatened and subject to national and international conventions. These mammals include humpback whales ("Megaptera novaeangliae"), who are commonly encountered in the area as they migrate north to their breeding grounds in June and July, and then again between September and November when
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
