According to our observations, the original Octopus's "inner beauty" is not via it!

I like to play, painting, and dancing, with artistic talents, dreaming of becoming an artist; there are six tentacles, two hands, and the other four are often used to move in both feet ... Octopus Brother as a brother as a tentacle ... as the octopus brother as a manner ... The important role in "SpongeBob" has a unique charm because of the cold appearance and the complex personality of the heart, which is impressive.

In fact, octopus, as a common marine creature, is indeed a bit like octopus. This is the highest "internal beauty" known as the highest IQ.

When people just discovered the octopus, they didn't notice how smart it was. On the contrary, it even felt that it was a bit stupid. More than 2000 years ago, the ancient Greek philosopher and thinker Aristotle evaluated the octopus: "They look stupid, they will not avoid the repeated fidelity of the hand, it is easy to be caught."

In fact, this is because the octopus is curious, likes to explore the surrounding environment, and the palm that appears in front of it just satisfies its curiosity, not its lack of intelligence. With the deepening of people's understanding of octopus, observing its strong color change ability, learning ability, and extraordinary nervous system, they suddenly realized that the octopus was so smart. This is unique in vertebrates.

Invisible

Octopus is a master of ambushing prey. He often hides behind the stone or waiting for the prey to approach the prey. arrive. What is even more surprising is that this kind of discoloration is completed instantly, and it disappears in the environment in a blink of an eye. Such a strain ability is not related to the nervous system of octopus.

Typical nerve reflex arcs usually include sensors, nerve, nerve centers, and neuropathy. The feelingr is responsible for receiving external stimuli, transmitting the nerve to pass the stimulus signal to the nerve center, and the nerve center analyzes and sends instructions to the transmission signal. It is reported that the nerve will then transmit the instruction information to the effect.

The discoloration process of octopus needs to first observe the surrounding environment, transmit environmental information to the brain, analyze and interpret the brain, and then send the specific operation instructions of color change to the skin. Thousands of pigment cells on the skin will change according to the instructions. , Complete the reflex arc completely, and finally achieve discoloration. The whole process was completed in just a few seconds, which made people have to sigh the efficiency of the octopus nervous system.

Look at me 72 changes

Mattering state refers to an ecological phenomenon that benefits one creature in the characteristics of form and behavior. There is a type of octopus called mimic octopus, which can imitate at least ten kinds of creatures such as lion fish, bi -fishes, and sea snakes through changes in body color, body, and behavior. "". The lion fish is full of long and sharp fins. In order to imitate it, the mimic octopus will stretch the wrist and foot in all directions and imitate it. Behind you, the neck shrinks, and the body is flattened; when the mimic octopus needs to be transformed into a sea snake, the six wrists and feet will be hidden into the sediment, leaving only two wrists outside, and then turning into the sea snake. Unique black and white stripes.

Mimic octopus

In order to realize the mimic state, the mimic octopus first needs to learn the characteristics of other animals during the preparation stage, remember this information, and confirm that it can imitate; when the actual situation occurs, the mimic octopus needs to be based on different opponents, clearly imitating the solution, accurate accurate Fast imitation can be used to turn danger. If there is no strong brain, it is difficult to achieve long -term memory, judgment and decision -making, and rapid response involved in the mimic process.

Happy life of clever ghosts

Escape master

Octopus often makes feats of "golden cicada" with the help of the intelligent brain. After the researchers found that the octopus was placed in a special maze, it could always find the correct escape path and escape the shackles of the maze.

In 2016, a octopus named Inky was successfully "jailbreak" in the aquarium in New Zealand. That night, the staff forgot to cover the water tank roof, which allowed Inkyic to use it. It escaped from the gap between the water cylinder head, explored on the ground, drilled into the drainage pipe mouth, along the drainage pipeline all the way along the drainage pipeline all the way all the way all the way to the drainage pipeline all the way. Crazy, finally returned to the sea, and regained freedom. The next day, the staff still broke the case through the water stains left on the ground. Some people also found that octopus can escape from the sealing jar of the lid, and the octopus in the jar even developed the method of unscrewing the lid by themselves, which is amazing.

Adapt to local conditions

Octopus can work hard to create conditions suitable for their own survival according to the specific environment. Octopus usually has its own nest. In order to prevent the nest from being snatched by other creatures, some octopus will take the initiative to pick up sand and stones to cover the caves after leaving the nest, making it difficult for potential competitors to discover their nests. A kind of octopus that lives in tropical likes to use coconut shells to avoid the enemy's attack. They drill into the coconut shell and "carry" coconut shells on the bottom of the sea. When moving, the octopus only stretched out two wrists and feet, and the front and rear swinging of the wrist and foot drove the entire body to move forward. A octopus curled up in the coconut shell

Play

In response to the challenge of survival, octopus is still a guy who is uncomfortable, and playing is a characteristic of high -intelligent creatures. Researchers invest in an empty plastic bottle in the water tank, and want to see what reactions have the octopus living in it. Driven by curiosity, the octopus first touched the plastic bottle with the wrist to see what this uninvited guest was going to do. After touching it for a while, the octopus began to spray water at the plastic bottle. The bottle hit the side wall of the water tank under the action of the water flow, and then rebounded to the octopus. This has aroused great interest in octopus, and it once again sprayed water at plastic bottles. It was repeated more than 20 times before and after it left with satisfaction.

In 2019, researchers even found that octopus may dream! They shot a takoy in a sleeping body constantly changing the body color, and the way of changing body color was very similar to that of its usual prey in prey. Therefore, this octopus may be dreaming of catching crabs at this time.

The reason for high IQ

Why does octopus evolve so many complex behaviors? What about such high intelligence? There is no accurate answer yet. It is generally believed that this is related to the survival status of octopus: as a soft and delicious software animal, many predators are jealous of octopus; octopus lacks strong offensive weapons, and the action is not agile, so that it is facing facing It is difficult to occupy an absolute advantage when prey. There are no sharp spears, lack of hard shields, and octopus's innate conditions are not good. If you want to survive, you can only think about other methods, and this method is to make yourself smarter.

The octopus has gone far and extreme on the way to make themselves smart. It has pulled its software animals and even all vertebrates. The nervous system of software animals is mainly composed of the ganglia. The ganglia refers to the nodular structure of neural cells. Software such as snails and oysters such as snails and oysters is relatively small, low degree of aggregation, and it is difficult to satisfy complex behavior. need. The octopus's gap is highly gathered, forming a tissue similar to vertebrate brain, and the brain partializes different functions to exercise different functions. Winning victory.

Octopus raises the body with eight wrists to observe the surrounding environment

The distribution of nerve cells in the octopus nervous system is also unique. One -third episode of nerve cells is concentrated in the head, and episodes of 2/3 are concentrated in 8 wrists. Treatment in nerve cells, which makes the wrist of octopus a certain autonomy. So after we see that the wrist of octopus is removed, even after a long period of time, it still has the ability to move, and the inner suction cup remains suction. Most of the nerve cells of vertebrates are concentrated on the head. It can be said that it has two completely different neurological systems as octopus, but both systems are very efficient and reflect the extraordinary intelligence level.
