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.
Portrait of a Bottlenose Dolphin. As members of the whale family, dolphins are fully aquatic mammals that spend their entire lives underwater. They only need to breath air from the surface once every 5 to 10 minutes using the blow hole at the top of their heads which is like a large nostril. There are almost forty different species of dolphins with the killer whale being the largest. The bottlenose dolphin is the species of Flipper fame that we are most familiar with, and the species that is regularly referred to as simply dolphin. The term dolphin is not synonymous with porpoise. Porpoises are six species within the dolphin family differentiated by their flat teeth.
