Dolphins can't talk to human beings. Many people generally think that dolphins have high intelligence. After training, captive dolphins can complete many difficult movements, but they still can't reach the realm of talking with human beings. Although dolphins can't communicate with humans, they have their own language system. According to research, dolphins communicate with their companions through ultrasound. By intercepting dolphins' ultrasonic waves, scientists found that they can also attack other fish with ultrasonic waves. When they emit ultrasonic waves, other fish's judgment and attack power will deteriorate.

Dolphins can interact with humans. They are gentle and very kind animals. In natural waters, if someone accidentally falls into the water, they may drag human beings to the shore, which is very friendly to human beings. In addition to natural interaction, farmed dolphins can also interact with humans. Although they can't understand human language, they can be rewarded with their favorite food when training. When they do the right thing, they are fed food. After a long time of training, dolphins will be familiar with the rules, and over time, they will complete the corresponding actions according to human instructions.
