Three heads and six arms have always been the super martial arts in China myths and legends, but in the real world, octopus has such super martial arts: three hearts supply blood at the same time, nine brains can think, and two sets of memory systems have backups. And its magical abilities are also called "alien creatures", but how can such a strong octopus become human food? In fact, don't underestimate it, its ancestors are really rich!
My ancestors were also rich.
The magical alien creature-Octopus
Octopus is called an alien creature, and even many people think that if human beings are extinct, octopus may be the next intelligent creature on earth because it has many magical places.
1, Octopus has great wisdom: According to people's research, the number of genes currently owned by humans is about 20,000 to 25,000, but Octopus has 30,000 genes. Although the number of genes does not determine the level of wisdom, there is no doubt that Octopus has a very large number of active neurons, which are basically similar to dogs. You know, among mammals, the IQ of dogs is already relatively good. As an invertebrate, it is a miracle of evolution that octopus can catch up with dogs across the life level, and the IQ of octopus is undoubtedly a proper brother among invertebrates.
I have many brains.
Scientists have done tests: someone put a glass bottle with lobster and a cork in front of the octopus. After several rounds of observation, the octopus wound its tentacles around the glass bottle, and after repeated attempts, it successfully pulled out the cork from the inside. Some people even put a crab in a bottle, and then put the bottle in a complicated glass box. Then I put it in front of a lovely new octopus and an experienced old driver who opened the bottle. I found that the lovely new octopus had no idea what to do, but the old driver skillfully opened the lid to eat crabs. After a short observation, the little octopus immediately learned this skill and opened the lid. This kind of learning ability seems to have surpassed some scum.
Lazy learner
Even octopus can play with toys, such as throwing a ball out and picking it up; I can simply use tools, run around with coconut shells, get in when I meet enemies, and walk a maze, which is much better than many road idiots. These advanced skills of imitating, playing, using tools and choosing routes are basically only available to top vertebrate players, while octopus actually exists, which can be said to be a model for leapfrog players.
I can unscrew the bottle cap.
2. Octopus has three hearts and nine heads: the size of octopus varies greatly. The smallest octopus is only 14 cm long, and the largest octopus is the giant octopus in the North Pacific Ocean. When their arms are unfolded, their diameter is15.6m and their weight is 53.6kg.. But they all have three hearts, one is responsible for supplying blood and oxygen to the whole body, and the other two are dedicated to supplying blood to the gills.
In addition, all eight tentacles of octopus have independent heads and can think independently. They can independently give instructions to each tentacle and complete complex actions. The main brain only needs to coordinate and link vision. For example, when going home, the brain only needs to send this instruction, and the brains of other tentacles of the octopus can decide how to exercise and send themselves to the sea. It's amazing.
Independent thinking
In addition, octopus has two sets of memory systems, which can remember things independently. There are some things that the brain may not know, but the tentacles remember, so if a female octopus asks the official seal fish: What did you do last night, didn't you know? Who is she? The official seal fish can calmly answer: I don't know what you said. I have no memory at all. Tentacles should have made it themselves. I had nothing to do with that. Perfect!
I didn't do it.
3. Octopus's eyes are n levels higher than human's: If you compare human's eyes with octopus's, you will find that human's eyes are simply things that designers have modified at will, full of bugs.
Comparison of human and octopus eyes
The human retina is roughly composed of three layers of cells, namely photoreceptor cells, bipolar cells and nodular cells. Among them, photosensitive cells are responsible for converting external optical signals into electrical signals, while bipolar cells are responsible for sorting out and processing these electrical signals. Finally, ganglion cells transmit these classified electrical signals to the brain to form the final image. Therefore, according to normal logic, photoreceptor cells should feel light at the outermost layer, and ganglion cells transmit the final signal to the brain at the innermost layer, while humans just stick it backwards.
It's not just the eyes that are upside down.
The photosensitive cells that need to receive light are actually inside, which leads to the need to pass through two layers of cells to receive light, which greatly reduces the imaging quality.
The photoreceptor cells are actually in the innermost part.
At the same time, the outermost ganglion cells need to pass through the retina again to reach the cranial nerve, which leads to a hole in the retina for the nerve to pass through. Is this design ridiculous? Octopus, on the other hand, has perfect structure, clear imaging and reasonable distribution, and is a defective product of human eyes.
The optic nerve pierces the brain.
Octopus whose ancestors were once rich.
The ancestor of octopus was actually brilliant, and even once dominated the earth, that is, the overlord of the earth in Ordovician: Hornstone, a terrible giant.
a maritime overlord
Look at this guy, his huge body reaches 5~ 10 meters, his extremely hard shell and sharp attack weapon. This is not a creature. This is a large screwdriver! Therefore, this thing can be said to be the dominant creature in the ocean at that time. Unfortunately, generation after generation, the earth patched up at this time and opened an information film: extinction. 480 million years ago, the first mass extinction occurred-the end of Ordovician. The huge horn stone didn't survive, and it went extinct directly, and the family fortune declined, which made the octopus lose the qualification to become a rich second generation.
Biological extinction
Of course, after all, thin camels are bigger than horses. Although the ancestor of octopus was extinct, this kind of defensive ability with shell has been handed down all the time, so Nautilus, a creature with no attack ability but too hard for you to chew, has not been extinct for 400 million years, and then evolved into a nautilus without meat to eat. Unfortunately, when it was about to make a difference, the fish developed, so the first emperor collapsed halfway.
Nautilus hides secrets in its shell.
Then why are octopus so chaotic? Can only say that direction is more important than hard work!
Defects of octopus
Octopus lives in the deep sea, and the oxygen content is insufficient, so the blood of octopus is blue, because it is rich in copper, which can better carry oxygen in the low temperature environment of the ocean, but it also makes the blood highly viscous. Their blood pressure is as high as 75 mm Hg (10 kPa), which is close to that of people. This is like a fighter in high blood pressure for octopus, so octopus brain can't get it.
Blue-blooded octopus
At the same time, it is precisely because of the huge blood pressure that octopus evolved three hearts to support blood in order to survive, while human beings only need one powerful heart to meet the needs of the whole body. Therefore, the octopus's three hearts are not powerful symbols, but the performance of insufficient evolution, just like trying to string together three Snapdragon 444 processors to achieve the performance of Kirin 980. It can be said that one core is in trouble, and many cores are watching!

In addition, the octopus's nine heads will also cause a lot of embarrassment, because these heads can think independently and the central brain is only responsible for coordination. This is like the grouping system in those days. What do you want, but the princes below may not buy your account, and even attack each other, so the octopus's feet sometimes don't listen to the command, and they will be tied together or even entangled. Although they were United when they fled for their lives, on the whole, it was their own play. If humans have an octopus system, you should always pay attention to whether your hands will suddenly get out of control and stick to your nostrils. Of course, at this time, you can confidently say to your girlfriend: I don't know anything. If you don't believe me, my hand moved first.
Another disadvantage of octopus is its cruel confinement, just like a curse. Once the offspring are born, the octopus mother will die of overwork, so there is no one to teach the little octopus after it is born, and there is no way to teach the experience that the mother has learned in this life. Octopus is about to start again, no matter what innovative discoveries are made in front, they are invalid. How can I get through customs without filing? Plus the life span of octopus is only a few years. There is not enough time to develop civilization from scratch, so the octopus for so many years is still a low-level animal. In fact, if human beings are cursed in this way, it is estimated that there will be no way to develop civilization, and it is also possible to return to ancient times.
Archiving is very important
The biggest advantage of octopus:
Seeing this, I wonder if you know what is the greatest advantage of octopus? Yes, as many people have guessed, the biggest advantage of octopus is its rich nutrition and delicious taste!
Octopus is the most evolved mollusk. Their muscle fibers are extremely slender, the diameter is only one tenth of that of fish, and the content of collagen in tough connective tissue is 3-5 times that of fish. This not only brings strong muscles to octopus, but also creates a rich taste of octopus. The meat taste is crisp and refreshing, and it is suitable for stewing, frying, frying, steaming and other cooking methods.
Octopus ball
Familiar octopus balls and granular octopus are all strong Q-bombs, which are simply a clear stream in soft glutinous flour, just like pearls in milk tea, giving people a soul and refreshing! Of course, just like most old women's cakes don't have wives, the octopus balls you bought outside don't guarantee that there are really octopus in them!
Octopus in Chili sauce
Octopus doesn't have to be great to make braised pork or Chili. The soft, waxy and boneless octopus rolled in the hot sauce, constantly absorbing the delicacy of the hot sauce, and the delicacy of the hot sauce was also wrapped. Don't be too delicious!
Iron squid
After hundreds of millions of years of evolution, from the fierce sea overlord to today's well-known food, thanks to the great efforts of the octopus family for so many years, they have finally become our favorite flavor. At the same time, the octopus with three hearts and two memory systems also tells us from personal experience that "three hearts and two memories" will not have a good end!
Emma. It smells good!
