PANTROPICAL SPOTTED DOLPHIN (Stenella attenuata): Western North Atlantic Stock
There are two species of spotted dolphin in the Western Atlantic — the Atlantic spotted dolphin, Stenella frontalis, formerly S. plagiodon (Perrin et al. 1987), and the pantropical spotted dolphin, S. attenuata. These species are difficult to differentiate at sea. The pantropical spotted dolphin is...
