Diet: Bottlenose dolphins are hunters who find their prey at the surface of the water, eating mostly fish and squid.

Predators of Dolphins: Some sharks (including tiger sharks, dusky sharks, and bull sharks) and orcas will prey upon dolphins. Dolphins are also often trapped in people's fishing nets.
