The primary shark predators of bottlenose dolphins are the bull shark, tiger shark, dusky shark and great white shark. Shark bite scars on dolphins indicate that sharks typically attempt to ambush dolphins from behind and below. Some researchers think that shark attacks may not even be an attempt to eat a dolphin.
Bottlenose dolphins, the genus Tursiops, are the most common and well-known members of the family Delphinidae, the family of oceanic dolphin. Recent molecular studies show the genus contains two species, the common bottlenose dolphin (Tursiops truncatus) and the Indo-Pacific bottlenose dolphin (Tursiops aduncus), instead of one. Research in 2011 revealed a third species, the Burrunan dolphin (Tursiops australis). Bottlenose dolphins inhabit warm and temperate seas worldwide.
