The stripe at the flipper is clearly separated from the upper part by thin white line. The number of the vertebrae is (are) 70.Tooth counts ranges 32-42 in each upper jaw, 30-40 in each lower jaw. In general, they inhabit in offshore waters.They are in small pods or in large pods of hundreds of dolphins. |
