The octopus is a mollusk, but their IQ is very high. They have a relatively developed brain. Researchers have found that they have 1 main brain system in addition to 8 parabrain systems at the same time. Their nervous system is also more developed. Their high IQ is reflected in many ways, such as they can unscrew bottle caps; and then they camouflage themselves to divert the attention of the same sex during the mating period. They will also camouflage when avoiding enemy attacks. A. How high is the IQ of octopus

The body structure of octopus is different from that of human beings and most other animals. For example, octopuses have 3 hearts and 2 memory systems. Their brain is also more developed, and researchers have found that after studying their brain structure, octopuses have 1 main brain system, as well as 8 sub-brain systems. Also, octopuses have a relatively developed nervous system. Although they belong to mollusks, the structure of their nervous system is similar to that of vertebrates.

All of these structures make octopuses highly intelligent, so they can perform activities that would be considered complex by other animals, such as unscrewing a bottle cap in an experiment, escaping through a hole in a glass tank, and so on. Octopuses also use their intelligence during mating time, for example, a male octopus may disguise himself as a female octopus in order to deceive the same sex that is dangerous to them. They also use their intelligence to camouflage themselves when they are in danger, for example, sometimes they will burrow into coconut shells to avoid being tracked by their enemies.

Second, the IQ of the octopus is equivalent to a few years old

Above has been introduced, the IQ of the octopus is very high, IQ high performance is very much. Some researchers have studied its IQ and found that the IQ of the octopus is at least equivalent to a 2-year-old person. Of course, the octopus itself is more species, they are more different, IQ will also have a relatively different, some octopus will be more intelligent. They can recognize themselves in the mirror, and clearly know their own ability, can be used, this kind of octopus IQ can be equivalent to at least three or four years old human.
