Alonnisos Marine Park ("Larus cacchinans"), and, nesting among the rocks, the "Apus capus" and "Apus melba", the rock nuthatch ("Sitta neumayeri"), etc. The existing flora also favours the presence of species of the family Sylvidae, e.g. the Sardinian warbler ("Sylvia melanocephala") and the blackcap ("Sylvia atricapilla"). Underwater fauna is also varied, with many benthic and fish species. Various species of dolphins and some whale species may be seen in the region, such as the common dolphin ("Delphinus delphis"), the striped dolphin ("Stenella coeruleoalba"), the bottlenose dolphin ("Tursiops truncatus"), the long-finned pilot whale ("Globicephala melas"), the sperm whale ("Physeter macrocephalus") and the Cuvier's beaked
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
