Nature: dolphins will take the initiative to rescue their peers when they drown. This is their nature to take care of their companions. This nature may be reflected in their communication with humans. Same mammals: some researchers believe that dolphins can detect that humans breathe with their lungs through ultrasound, so they believe that humans are similar to them. Emotion: some researchers believe that dolphins also have rich emotions, which can be expressed when communicating with humans. 1、 Will dolphins get close to people? Dolphins are intelligent creatures and prefer to get close to humans. 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 people when they accidentally fall into the water or enter the deep water. These are the concrete manifestation of dolphins' friendliness to humans. 2、 Why dolphins are close to people has been introduced 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 are more convincing explanations:
1. Nature: dolphins are aquatic mammals. They need to breathe with their lungs. When breathing, they need to go above the water surface. When they were young, they began to breathe on the water regularly. When their companions drowned, they would take the initiative to rescue them. 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. Same mammals: dolphins 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 creatures with high IQ, and some biologists think they also have emotion. When communicating with humans, they will also show certain emotions, so they are more friendly to humans. （HaiTunHuiQinJinRenMa，WeiShenMeHuiQinJinRen）
