The octopus is a mollusk, but the IQ is very high, even higher than that of some vertebrates. The octopus's intelligence has a lot to do with their brain system and nervous system, they have a main brain and sub-brain system, and a well-developed nervous system. Their intelligence is reflected in many ways. For example, they have a very good memory; another example is that they can use their intelligence to camouflage themselves. They can find suitable cover and also disguise themselves as other animals. First, octopus smart

Octopus is a relatively intelligent creatures. Although they are only a class of mollusks, but their IQ will be higher than the IQ of some vertebrates. Octopus smart with their brain system has a lot to do with the study found that their brain structure is very special, they have both the main brain and the sub-brain system, at the same time their nervous system is more developed, such as nerve fibers and neurons and other structures.

The intelligence of the octopus is reflected in many aspects. For example, they have a very good memory ability, which is reflected in many experiments. Another example, the octopus will be based on the specific situation to disguise themselves, they not only have a very strong ability to change color can be used for camouflage, and they will also use their own smarts to avoid the enemy, for example, they will be drilled into some cover to cover their tracks, but also disguised as other creatures to confuse the enemy.

Second, the octopus and squid than who is smart

The octopus and squid belong to the mollusks, from the appearance of the two have a lot of similarities, but they are different types of organisms, in many aspects are different. For example, IQ, the difference between the two is relatively large. After a comparative study, it was found that the octopus is much smarter than the squid. Above has introduced the octopus smart, it can be said that they have "conceptual thinking", can complete some complex actions, to solve some relatively difficult problems; they also have a relatively strong memory ability. But the squid is different, they also have a similar nervous system, but their brain system is far less than the octopus.
