https://en.wikipedia.org/wiki/Dolphin#Natural_threats https://en.wikipedia.org/wiki/Dolphin#Natural_threats > Except for humans (discussed below), dolphins have few natural enemies. Some species or specific populations have none, making them apex predators. For most of the smaller species of dolphins, only a few of the larger sharks, such as the bull shark, dusky shark, tiger shark and great white shark, are a potential risk, especially for calves.[117] Some of the larger dolphin species, especially orcas (killer whales), may also prey on smaller dolphins, but this seems rare. Thus, the answer to 'Are dolphins on the top of the food chain?' is 'which species of dolphin?'
