Dolphins are a very cute animal, and they are also recognized as very smart animals. This is reflected in many ways. For example, when dolphins find their companions drowning, they will immediately swim to their side and lift them to the top of the water to breathe air; When they find humans drowning, they react similarly, lifting them into the air or pushing them directly to shore or shallow water. In aquariums, dolphins are also smart, they can complete many creative and difficult activities, but also with human interaction in various forms.
As mentioned above, dolphins are very smart, and their intelligence is reflected in many aspects. The main reason why dolphins are smart is that their brains are very developed. Biologists have done special research on this.
In terms of weight, dolphin brains are relatively heavy, comparable to human brains, and sometimes even heavier than human brains. When studying the brain structure of dolphins, researchers also found that the number of sulci is very large, indicating that their brains are developed. From the brain contains nerve cells, not only the number of cells, but also the density is very large. These characteristics are the reason why dolphins are smart. With this brain structure, dolphins not only have good memory, but also have large brain capacity and excellent information processing ability. And, interestingly, the dolphin brain is resting separately, and one side is still functioning while the other side is resting.
