Short-beaked common dolphin yellow or gold in front and dirty grey in back. It has a long, thin rostrum with 50–60 small, sharp, interlocking teeth on each side of each jaw. Juvenile dolphins have a more muted appearance and become more distinguishable when they mature. The short-beaked common dolphin is a member of common dolphin genus, "Delphinus", within the dolphin family, Delphinidae. 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". Currently, there are two recognized species of "Delphinus": the short-beaked common dolphin and the long-beaked common dolphin
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
