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.
Producers are the base of the food chain and make their own food. Primary consumers eat producers and secondary consumers eat the primary consumers. Tertiary consumers, like dolphins, are an important part of the food chain and keep the other species in balance. There are over 40 species of dolphins, all of which are aquatic mammals. The bottlenose dolphin lives in tropical salt water environments and eats secondary consumers like tuna.
