How smart are octopuses really, and are octopuses smart?

Octopuses have proven to be the most intelligent invertebrates to date, and octopuses are also known as primates bred in the sea.

Although the octopus is an invertebrate in terms of attributes, it can be said to be an "outlier" among invertebrates in terms of its nervous system development, and the octopus actually has 500 million nerve cells, which is almost an order of magnitude to kill other invertebrates.

Octopuses are considered to be the most intelligent of invertebrates.

1 The octopus has three hearts, two memory systems, and 500 million neurons in the brain.

2 The nervous system of the octopus is the most complex and advanced of the invertebral propulsions, including the central nervous system and the peripheral nerves, and the auditory, olfactory, and optic nerves are divided into the cranial ganglia.

3 Its unique neural structure makes it more capable of thinking than ordinary animals, and only 40% of the octopus's neurons are in the brain, and the remaining 60% are distributed in the brachiopods. So, we chose Octopus for the World Cup.

4 The number of neurons in an octopus is even close to catching up with the number of neurons in cats.

5 The octopus's genes are very unique and rarely found in other organisms, so it looks like an "alien organism" in the genome of an octopus.

The IQ of an octopus is equivalent to that of a human about 2 years old. An untrained octopus can easily unscrew the cap of a bottle that traps it, recognize different faces, and even get out of an artificially constructed maze with experience and memory alone.

Generally speaking, the number of neurons is used in the scientific community as an important criterion for judging the intelligence of animals. Octopuses have two memory systems, 500 million neurons, a main brain, and 8 epibrains in brachiopods. Only 40% of the neurons are concentrated in the main brain, and the rest of the neurons are evenly distributed among the 8 brachiopods, each of which can think and act independently, and the octopus has more neurons than many mammals, which is also evidence of the octopus's extraordinary intelligence.

Octopus

All the organs of the octopus grow on the head, the mouth grows on the body**, the body is round, there are 8 tentacles, and there are two rows of straws on the tentacles, which are widely distributed in the tropical and temperate waters of the world's oceans.

Introduction: Speaking of octopus, many people will find it very strange, one head has many feet, and some people will think that the octopus has a high IQ. In addition, in some science fiction movies, there are often plots in which octopuses attack humans and even defeat humans.

So how high is the IQ of the octopus, and can the octopus rule the world?

In fact, there are many types of octopuses on the earth, and the size is not the same, some are very large, some are very small, and some are edible, that is, the color is more transparent. Most octopuses live in rocks at the bottom of the sea, and these octopuses don't usually move. However, compared to invertebrate one, octopuses do have the highest IQ among invertebrates.

They can use their bodies to attract and quickly catch food. However, octopuses do not have as high IQ as people think, because invertebrates usually have lower IQs than vertebrates. Although octopuses are said to have a high IQ among invertebrates, there is no way to compare them with vertebrates, or even humans, so the IQ of octopuses is very low from a human point of view.

Therefore, it is impossible for octopuses to rule the world, and it is completely useless to have such an idea, so there is no need to worry about such a problem. The octopus is just an ordinary creature in the ocean and does not pose any threat to human survival.

Although the octopus looks terrible in film and television works, it is very important for biodiversity, so you must not be misled by film and television works, and do not kill Zhang Wuyu at will in daily life, in fact, every link in the ecological chain is very important. Therefore, we must learn to protect the environment, and the degree of biodiversity is more abundant, so that the entire ecological chain will be more stable and human life will be more beautiful.

The IQ of the octopus is very high, because someone has tested the IQ of the octopus and found that the IQ of the octopus has surpassed that of humans. It is true that the IQ of the octopus can rule the world, but the octopus is relatively small, so it does not meet the requirements of world domination.

The IQ is very high, of course, you can't rule the world, because of the way of life, you live at the bottom of the sea, so there is no way to develop well.

Octopuses should have a very high IQ, and their IQ is not capable of dominating the world because they are lower creatures.

Although octopuses are mollusks, they have a high IQ, even higher than that of some vertebrates. The intelligence of octopuses has a lot to do with their brain system and nervous system, they have a main brain and a secondary brain system, as well as a well-developed nervous system. Their cleverness is manifested in many ways.

For example, they have a very good memory; For example, they use their wits to disguise themselves. They can find suitable shelter and can disguise themselves as other animals. <

The octopus is a relatively intelligent creature. Although they are only a class of mollusks, their IQ is higher than that of some vertebrates. The intelligence of octopuses has a lot to do with their brain system, and studies have found that their brain structure is very special, they have both a main brain and a secondary brain system, and their nervous system is also relatively developed, such as nerve fibers and neurons.

The intelligence of the octopus is manifested in many ways. For example, they have a very good memory, which has been shown in many experiments. For example, octopuses will disguise themselves according to the situation, not only do they have a very strong ability to change color for camouflage, but they will also use their intelligence to avoid enemies, such as they will burrow under some cover to cover their tracks, and they will also disguise themselves as other creatures to confuse enemies.

Octopuses and squid are both mollusks, and there are many similarities between the two in appearance, but they are two different creatures and are different in many ways. For example, in terms of IQ, the difference between the two is relatively large. After a comparative study, it was found that octopuses are much smarter than squid.

The cleverness of octopuses has been introduced above, and it can be said that they have "conceptual thinking" and can complete some complex actions and solve some relatively difficult problems; They also have a strong memory. But squid are different, they also have a similar nervous system, but their brain system is far inferior to that of octopuses.

The octopus is a very intelligent creature, although its IQ is about as ordinary as a human child of three or four years old, but its body structure is very different, according to the research of scientists, the genetic structure of the octopus is different from any kind of creature on earth, and it is no wonder that the octopus is suspected to be an alien, a creature from an alien planet.

The octopus has eight heads of starlings, and in addition to the brain of the main body, each brachiopod has a brain, and its brachiopods can stop acting autonomously, so it can complete the situation of multitasking. Some people will ask, why does the octopus have eight brachiopods and only eight heads with the body? One of the brachiopods of the octopus is very valuable, and it also maintains this brachiopod very well, this brachiopod has the function that other brachiopods have, and also has the mating function that other brachiopods do not have, so it is very different.

The octopus is among the top of the list, but not the highest, and its IQ is not as high as that of chimpanzees or other mammals such as dolphins and monkeys, but the octopus is an invertebrate mollusk and is so intelligent that it is the best of their class.

The octopus can be regarded as an escape master in the animal kingdom, in addition to being very smart, its wrists and feet are very sensitive, through the cooperation between the hand and the brain, even if the octopus is trapped in the jar, it can escape from the jar through observation and theoretical victory. Since the body has no bones, the only hardest thing is the beak in the mouth, so the octopus with its own "bone reduction technique" can escape from any small hole. Different species of octopuses have different evolutionary ideas, and some small octopuses with weaker bodies have evolved fearful poison, such as the blue-ringed octopus.

However, evolving venom consumes too much energy from the body, so some octopuses choose to pretend. The fox and the tiger can maintain their own safety very well, it can be the same as the surrounding environment, and it can even be imitated as other creatures.

It is inevitable that biologists will be frightened by such intelligent animals in nature, but fortunately, without fire in the sea, it is difficult to present other cultures, otherwise the clever octopus may have invented a world in the ocean.

The octopus has a very high IQ, and it is very intelligent, and he likes to be alone, and will hide in the crevices or caves of the stones all year round; The octopus does not rule the earth, although his IQ is particularly high, but for some other reasons, he does not have the ability to rule the earth, and his development system is not particularly complete.

Octopuses have 9 brains and are currently the most intelligent invertebrates on the planet. It is impossible for octopuses to rule the earth, because they cannot do without water, they are cervical-free animals, and their combat effectiveness is relatively poor.

I think the IQ of octopuses is very high, because there are many scientific studies that show that octopuses can imitate some human behaviors, and octopuses also have a very rich ability to express emotions; Octopuses do not rule human life, octopuses have very high IQs, but their IQ is still insufficient compared to humans.
