**What are the common dolphin predators?**
The only predator that dolphins have in the ocean are sharks. Some cases of killer whales eating dolphins have been recorded, but this is not a common behavior. In fact, killer whales are dolphins too. However, the most dangerous predator dolphins have today are humans and although we are not in the sea, we kill more dolphins than any other animal in the ocean.
