Delphinus is a genus of dolphin, commonly known as the "Common Dolphin". There are two species in this genus, the Short-beaked Common Dolphin (Delphinus delphis), and the Long-beaked Common Dolphin (Delphinus capensis). But some studies say that there is a third species, the "Arabian Common Dolphin" (Delphinus tropicalis), which has a long, thin beak and is found in the Indian Ocean and the Red Sea.
