Dolphins can be said to be the nemesis of sharks, because dolphins not only swim faster, but also are more flexible. Sharks are fierce, but clumsy. Dolphins can easily attack sharks, but sharks can't attack dolphins. And most sharks' bones are not hard enough. If dolphins hit sharks' bodies with their hard beaks, the sharks' internal organs are likely to break and die.

Secondly, sharks generally move alone, but dolphins are social animals, and the number of dolphins will have a great advantage. Finally, dolphins have special sound waves. When they attack through sound waves, most fish will reduce their judgment, and sharks will also be affected by sound waves. Whether it's singles or group fights, sharks don't have much chance of winning against dolphins. So dolphins can be regarded as the nemesis of sharks.

Although dolphins are gentle in character and don't like to attack other creatures, their attack power is actually very strong. Moreover, their IQ is relatively high, and they will call their relatives and friends through sound waves, so that most dolphins will quickly gather together. Moreover, they are more United, and they will use their beaks to hit the enemy at the same time until the enemy escapes or dies.
