The dolphin is a kind of intelligent creature, and it is also a kind of creature that likes to be close to people. They are very friendly to humans, generally do not attack humans, but also interact with humans in various forms. More importantly, they may take the initiative to rescue humans when they accidentally fall into the water or enter the deep water area. These are all concrete manifestations of dolphin friendliness to human beings.
As mentioned above, dolphins are relatively close to humans. Biologists think this phenomenon is more interesting, so they have done some research on dolphins. Different biologists have different explanations for this phenomenon. The following three explanations are more convincing:
1. Nature: Dolphins are aquatic mammals. They need to use their lungs to breathe. When they breathe, they need to go to the top of the water. From a relatively young age, they began to breathe regularly to the surface, in the event of drowning companions, they will take the initiative to rescue, this is their nature to take care of their companions. This nature may be reflected in their communication with humans, so they are very friendly to humans.
2, the same mammals: dolphins will use ultrasound to detect. Some biologists believe that dolphins can detect that humans also breathe with lungs, so they will regard humans as the same creatures as them, so they are more friendly to humans.
3. Emotion: We all know that dolphins are highly intelligent creatures, and some biologists believe that they also have emotions. When communicating with humans, they also show certain emotions, so they are friendly to humans.
