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")
