Dolphins are mammals that live in the water. They are also social animals, and they are social animals with delicate emotions. They are very United with each other. When their companions are in danger, they will unite to resist the invasion from other animals. Even when sharks encounter a group of dolphins, they will bypass, because a single shark can not resist a group of dolphins. When one of the dolphins in the group is sick, the other dolphins will be around to take care of it. In addition, when a female dolphin in the group gives birth to a calf, the other dolphins in the group take turns to take care of the calf until it has mastered all the survival skills.
Moreover, in a group, dolphins have their own language system, and they communicate with each other through their own language. At present, there is no way for humans to fully interpret dolphin language.
As mentioned above, dolphins generally live in groups, and dolphins in a group will find ways to take care of other dolphins. After studying this phenomenon, biologists have come up with the following reasons:
1. Potential threat: Although dolphins themselves are relatively fast, if they are single dolphins, their attack power is still relatively weak. When they encounter large and relatively fierce animals, they may not be able to resist their attack. Therefore, in order to defend against this potential threat, dolphins need to unite and appear collectively.
2. High IQ: Dolphins themselves are creatures with relatively high IQ, so they know that a collective existence will be beneficial to their survival.
