Is the IQ of Octopus high? How old is it

Although octopus is a kind of Cephalopod, its IQ is relatively high, even higher than that of some vertebrates. They have a lot of high IQ. For example, when researchers want to use electrodes to study the brain, they will directly pull out the electrodes; They also have the ability to use information to make decisions. After research, it is found that the IQ of octopus is roughly equivalent to that of 2-year-old human. There are also some octopus species with higher IQ, which can reach the level of human 3-4 years old. 1、 Does Octopus have a high IQ? Octopus belongs to cephalopods, that is, animals with developed heads and many tentacles at the same time. Their brain structure is quite strange. Although the position of the brain is also in their head, it is long around their esophagus, because their esophagus is also in the head, which is incomprehensible to other animals and people. Although the brain and body structure of octopus are different from humans and other intelligent animals, many experiments have proved that octopus's IQ is very high.

For example, in one experiment, researchers wanted to put electrodes into the octopus's brain to observe their brain signals. However, octopus seemed to know the purpose of the researchers. They would choose to cut off the blood supply to this brain region, and some even pulled out the electrodes themselves. In other experiments, researchers found that octopuses use their known information to make decisions. For example, when it comes to mating season, male Octopus disguises himself as a female octopus in order to reduce the hostility of the same sex to them. For another example, some Octopus have a strong sense of protecting themselves. Sometimes they disguise as halibut to avoid the attention of some predators. 2、 Octopus IQ is equivalent to how old people are. As described above, octopus IQ is relatively high, and there are many specific manifestations of their high IQ. After biologists became interested in their IQ, they did special research and found that the IQ of octopus is roughly equivalent to that of humans around the age of 2. However, not all Octopus have the same IQ. Some Octopus have higher IQ, which can be equivalent to three or four-year-old humans. (ZhangYuDeZhiShangGaoMa,XiangDangYuRenJiSui)
