How high is the IQ of dolphins?

The IQ of dolphins is equivalent to that of human children aged 6-7.

Scientists compared the brains of orangutans, humans and dolphins. Dolphin's brain weighs almost the same as human's, which is 1.6kg and 1.5kg respectively, while orangutan's brain is only one sixth of human's, that is, 0.25 kg. All these are enough to prove that dolphins have higher IQ than chimpanzees, and chimpanzees have the same IQ as humans, that is to say,

The IQ index of dolphins is between 140- 160, which is obviously higher than the animal average of 60. Once a zoologist dissected the cerebral cortex of bottlenose dolphins and found that their brain folds had this amazing function of increasing brain cells and volume, and even related to each other. It can be said that the number of ditches is extremely rich, and the number and depth of ditches are only one of the criteria for testing whether IQ is developed or not.

How smart are dolphins?

Dolphins are animals with high IQ. They have always attracted people's attention in animal shows in aquariums. Through human training, dolphins can perform many wonderful programs, such as high jump, circle drilling, basketball, handshake interaction, singing and even painting.

The relationship between dolphins and humans is also very harmonious. There are many touching stories about dolphins saving lives in the world. When dolphins find someone drowning, they will lift him up and push him to the shore. Some people say that dolphins are practicing to rescue their companions. Because dolphins live in water, they still need lungs to breathe, so they sometimes drown themselves.

Dolphins are highly socialized animals. When they find their companions drowning, they will lift them out of the water to breathe. According to this logic, it seems that dolphins save lives by nature, but most people are still willing to believe that dolphins save lives by wisdom.

The intelligence of dolphins is not only reflected in this point, but also an oceanographer found that dolphins have their own language. He recorded all kinds of calls of dolphins for research. Finally, it is found that dolphins can indeed transmit information with their own voices and understand the meaning of some artificial voices. Moreover, the dolphin's own unique call signal can also communicate with its companions.
