Long-beaked common dolphin to 60 small, sharp, interlocking teeth on each side of each jaw. They have more teeth than any other delphinids. The long-beaked common dolphin is a member of common dolphin genus, "Delphinus" within the dolphin family, Delphinidae in the cetaceans order. Until the mid-1990s, the different forms within "Delphinus" were not recognized as separate species, but were all considered members of the species "D. delphis". In 1994, Heyning and Perrin did research on these species and then Kingston and Rosel confirmed there were two separate species. Currently, the two recognized species of "Delphinus" are the short-beaked common dolphin ("D. delphis")
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
