Common dolphin Common dolphin The common dolphin is the name given to two species of dolphin making up the genus Delphinus. Taxonomists and cetologists usually recognise two species — the short-beaked common dolphin, which retains the systematic name "Delphinus delphis", and the long-beaked common dolphin "D. capensis". Despite its name, the common dolphin is not the dolphin of popular imagination; that distinction belongs to the bottlenose dolphin (genus "Tursiops") due to its widespread use in marine parks and its appearance in the television series "Flipper". However, this dolphin was the most frequently represented in the art and literature of ancient Greece and
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
