1. Fast: Great white sharks are not as fast as dolphins, and dolphins are more flexible, so dolphins can easily attack great white sharks. But great whites can't attack dolphins. When great whites meet dolphins, their combat effectiveness will decrease.

2, large numbers: Great white sharks are usually solitary, while dolphins like to live in groups. When one dolphin is attacked, other dolphins will attack in groups. In addition, dolphins' most powerful thing is their beak. Under high-speed attack, great white sharks may have broken internal organs.

3. Sonic attack: Dolphins are most characteristic of their sonic attack. When they encounter great white sharks, they will send out sonic attack first. This kind of sound wave will affect the fish's judgment and reduce the original combat effectiveness, so dolphins have a great advantage in fighting alone when encountering great white sharks.

Dolphins are at the top of the food chain in marine life, so they don't have many natural enemies. Except for some fierce killer whales and tiger sharks, there are basically no enemies. Because the bones of killer whales and tiger sharks are relatively hard, the beak of dolphins can't pierce their bones, and the attack power and aggressiveness of killer whales and tiger sharks are very strong, dolphins may be in great danger when they encounter them.
