The octopus actually has nine brains! Does its intelligence crush most living things?
Some people always say that octopuses are the most intelligent creatures in the world and can even rule humans if they come to land! So, are octopuses really that scary?

I believe many people have seen octopus, especially friends in coastal areas. Octopus has been made into various delicacies, such as octopus balls , spicy octopus, etc., but you will definitely not think of it. It is very intelligent and may even be the smartest creature in the ocean.
The octopus is a kind of marine mollusk . It looks very strange. It consists of eight long tentacles and a big head that is completely inconsistent with its body shape. The tentacles are also covered with small suckers. The octopus also relies on these suckers to walk. and grabbing items.
Octopuses vary greatly in body length, most are under 2 meters, but one type of octopus is very large, which is the Pacific giant octopus . Their size can even reach more than ten meters, the top predator in the ocean Or great white sharks are also their prey targets.

This kind of octopus often appears on the big screen as a sea monster. However, currently, the largest octopus known to humans is about 9.1 meters long and weighs 272 kilograms, which is far from reaching the sea level. Weird level.
The unique appearance of the octopus was once thought to be an alien creature. The octopus has a main brain and eight accessory brains. The eight accessory brains are respectively grown on the eight tentacles of the octopus. Each of the eight accessory brains has an independent nervous system.
When it encounters an invincible enemy, it will abandon one of its tentacles. The tentacles separated from the octopus' body will continue to move to attract the enemy's attention, while the octopus itself will escape.

In addition, the octopus also has three hearts. Each of the three hearts performs its own duties and can better maintain body functions. It can be said that the octopus has the most advanced body structure in the biological world.
Octopus has so many brains, does that mean it is really smart?
As we said before, the octopus has nine brains, and each brain can work independently. According to scientists' theories, the greater the proportion of the brain in the body, the higher the intelligence of the creature. So how smart is the octopus?

The intelligence test of octopuses starts in 2008. In the 2008 European Football Championship , someone did such an experiment. First, they prepared two transparent boxes with the flags of the two sides on them.
They took out an octopus named " Paul " from an aquarium in Germany, and then they asked "Paul" to choose the box to enter. The one he chose represented which team "Paul" thought would win. , this experiment was divided into six times in total. What is unexpected is that "Paul" succeeded in predicting four times.
However, this was not over yet. In the 2010 World Cup, "Paul" played again. This time, the prediction results were even more terrifying. He was correct seven times. Unfortunately, "Paul" failed not long after.

These two octopus prediction events have made more people curious about the intelligence of octopuses, and they have also done many interesting experiments, such as shutting the octopus in a glass jar and using its tentacles to unscrew the bottle cap. Escape; and put the octopus in a maze, and the octopus crawled out of the maze with its powerful analytical ability.
In addition to intelligence, octopuses also have strong learning and imitation abilities. Octopuses have some of the abilities of chromatophores, that is, their skin color can change with changes in the environment, and they can also imitate the actions of other marine creatures . Scientists also call the octopus "the primate of the ocean."

Everyone knows that we humans are the most intelligent creatures in the world, and octopuses are the smartest creatures in the ocean. If one day they come to land, can they threaten the dominance of humans? Woolen cloth?
First, let’s take a look at the detailed data of the octopus. According to data released by the authoritative biological research institute, the octopus has more neurons in its body than most vertebrates. The number of neurons has reached 500 million, and humans are the most loyal. Dogs have just over 400 million neurons.
The number of neurons determines the intelligence of a creature to a large extent. Generally speaking, the higher the number of neurons, the higher the intelligence of the creature. On the contrary, the fewer the number of neurons, the lower the intelligence of the creature.

The intelligence of some adult dogs is roughly equivalent to that of a two or three-year-old child. In other words, the intelligence of an octopus is definitely not lower than that of human infants, and an adult has about 86 billion neurons. Even a hundred octopuses combined have less neurons than an adult.
Now let’s compare octopuses with lower primates. Chimpanzees, as the primates closest to humans, have 6 billion neurons, which is about 12 times as many as octopuses. Chimpanzees can be ruled by humans. , not to mention a tiny octopus.

In addition to intelligence, there is also a big gap between octopuses and humans physically. The height of an adult is about 1.7 meters and the weight is more than 60 kilograms, while an adult octopus is smaller than a human. There are many. Even if octopuses have relatively high intelligence, humans can crush them with their strong bodies.
still has lifespan. The average lifespan of humans has reached 70 years, and the lifespan of an octopus is only three or four years at most. Even if it is boiled, it can kill them. Therefore, octopuses will not be a threat when they come to live on land. human's.
