Three heads and six arms have always been super combat skills in Chinese myths and legends, but in the real world, octopuses have such super skills: 3 hearts supply blood at the same time, 9 heads can think, 2 sets of memory systems and backups. And the various magical abilities it exhibits also make people call it "alien creatures", but how can such a strong octopus become a human delicacy? In fact, don't underestimate it, it is really generous in its ancestors!
Magical alien creatures - octopuses
The reason why octopuses are called alien creatures, and even many people think that if humans go extinct, octopuses may be the next intelligent creatures on Earth, because it has a lot of magical places.
1, octopus has a strong wisdom: according to people's research, the current number of genes possessed by humans is about 20,000 to 25,000 groups, but octopus has 30,000 sets of genes, although the number of genes does not determine the level of wisdom, but there is no doubt that the octopus has a very large number of active neurons, basically similar to dogs, to know that in mammals, the iq of dogs has been relatively ok, octopus as an invertebrate can actually cross the life level to catch up with dogs, It is already an evolutionary miracle, and there is no doubt that the IQ of octopus is a proper brother among invertebrates.
I have a lot of brains
Scientists have done tests: someone put a glass bottle containing lobsters and the bottle mouth is blocked with a cork stopper in front of the octopus, the octopus after several rounds of observation, wrapped the glass bottle with tentacles, tried repeatedly and successfully pulled the cork out of it, and even people put a crab in the bottle to tighten the stopper, and then put the bottle in a glass box with a complex structure, and then put it in front of a cute new octopus and an experienced bottle opening old driver octopus, and found that the new octopus did not know what to do, The old driver skillfully opened the lid to eat crabs, and after a short observation, the little octopus immediately learned this skill and opened the lid. This learning ability seems to exceed some scum.
Scum
Even octopuses will play with toys, such as throwing a ball out and picking it up; they will simply use tools, run around with coconut shells, drill in when they encounter enemies, and walk mazes, which are much better than many road fools, these imitations, play, use tools, route choice advanced skills, basically only the top player mammals of vertebrates have, and octopuses will actually exist, which can be said to be a model for cross-level players.
I would screw the cap
2, octopus has 3 hearts, 9 heads: octopus body size difference is very large, the smallest octopus is only 14 cm in length, is the Atlantic pygmy octopus, the largest is the North Pacific giant octopus, after their arms are unfolded, the diameter is 15.6 meters, the weight is 53.6 kg. But they all have three hearts, one heart is responsible for the blood supply and oxygen supply to the whole body, and the other two hearts are dedicated to the blood supply to the gills, and the division of labor cooperates.
In addition, the octopus's 8 antennae have a separate head on it, can think independently, they can give instructions to each tentacle alone, complete complex actions, the main brain only needs to be responsible for coordinating and linking vision, such as going home, the brain only needs to issue this command, the octopus's other antennae brain can decide how to move, send themselves to the sea, very magical.
Think independently
In addition, the octopus also has two sets of memory systems, can independently remember things, some things, the brain may not know, but the tentacles remember, so if there is a female octopus ask the male octopus: What did you do last night, do you not count in your heart? Who she was when. The male octopus can calmly answer: What do you say, I don't know ah, there is no memory at all, it should be the tentacles themselves, it has nothing to do with me Ha, perfect!
I didn't do it
3, octopus eyes are N grades more advanced than humans: if you compare human eyes with octopuses, you will find that human eyes are simply something that designers have scribbled and are full of bugs.
Contrast between human and octopus eyes
The human retina is roughly composed of 3 layers of cells, photoreceptor cells, bipolar cells, and nodular cells. Among them, photoreceptor cells are responsible for converting external light signals into electrical signals, while bipolar cells are responsible for classifying and processing these electrical signals. Finally, the ganglion cells transmit these classified electrical signals to the brain, forming the final image. So according to normal logic, photoreceptor cells should feel light in the outermost layer, and ganglion cells send the last signal to the brain in the innermost layer, but humans just stick to it.
It's not just the eyes that are the opposite
The photoreceptor cells that need to receive light are actually in the innermost part, resulting in two layers of cells needing to pass through before the light is received, which greatly reduces the image quality.
The photoreceptor cells are actually in the innermost part
At the same time, the outermost ganglion cells need to re-enter the retina to reach the cranial nerves, which causes the retina to actually wear a hole here to let the nerves pass. The octopus, on the other hand, is a perfectly structured, well-imaged, well-distributed, and properly defective product for the human eye.
The optic nerve penetrates into the brain
The octopus that was once generous on the ancestors
The ancestors of the octopus are actually very brilliant, and it can even be said that they once dominated the earth, that is, the overlord of the earth in the Ordovician period: the terrifying giant House Horn Stone
Overlord of the sea
Look at this guy, the huge body reaches 5 to 10 meters, the incomparably hard shell, the sharp attack weapon, where is the creature, this is a large cone! So this thing in the sea at that time can be said to be a hegemonic creature, across the ocean, but it is a pity that a generation of patches a generation of gods, the earth at this time hit a patch, opened the expansion pack: biological mass extinction. 480 million years ago, the first mass extinction occurred, the mass extinction at the end of the Ordovician. The bulky and huge horn stone failed to last, and it was directly extinct, and the family fell in the middle of the road, so that the octopus also lost the qualification to become a rich 200,000 generations.
Mass extinctions
Of course, after all, the skinny camel is bigger than the horse, although the octopus ancestor is extinct, but this shelled defense ability has been handed down, so later evolved the nautilus that has no offensive ability but is hard enough that you can't bite, relying on this shell to lie flat for 400 million years without extinction, and then evolved to eat the fleshless ammonite, unfortunately, when it was planning to do something, the fish developed, so the first emperor did not half of the business and the middle road collapsed, and then there was no chance to rise, until today it has become a human delicacy.
The shell of the Nautilus hides secrets
So why are octopuses mixed up to this point? It can only be said that the direction is more important than the effort!
The flaws of the octopus
Octopus lives in the deep sea, oxygen content is insufficient, so the octopus blood is blue, because it is rich in copper, which in the low ocean environment, can better carry oxygen, but this also makes the blood have a high degree of viscosity, their blood pressure is as high as 75 mm Hg (10 kPa), has been close to the human, which is the octopus this small size creature is simply a fighter in high blood pressure, so the octopus brain can not get enough oxygen to think and evolve, as long as it does not go out of the deep sea, There is no potential for development.
'Blue-blooded octopus
At the same time, it is precisely because of the huge blood pressure, so the octopus in order to survive, evolved three hearts to be responsible for the supply of blood, and the strong heart of human beings, only one can meet the needs of the whole body, so the octopus's three hearts are not a symbol of strength, but a manifestation of insufficient evolution, just like the use of three Snapdragon 444 processors strung together in a vain attempt to achieve the performance of Kirin 980 is the same, it can be said that it is a nuclear difficulty, multi-core onlookers!
Onlookers
In addition, the nine heads of the octopus will also cause a lot of embarrassment, because these heads can think independently, the central brain is only responsible for coordination, which is just like the sub-sealing system of that year, you Zhou Tianzi said what to do, but the princes below may not necessarily buy your account, and may even attack each other, so the octopus's feet sometimes do not listen to the command, will be knotted together, and even circled together, although when fleeing for their lives, they are united, but generally they are playing their own. If humans have an octopus system, you always need to pay attention to whether your hand will suddenly get out of control and insert itself into your own nostrils. Of course, at this time, you can also say to your girlfriend with a straight face: I don't know anything at all, you don't believe it, it's my hand that moves first.
Another disadvantage of the octopus is a very cruel confinement, as a curse, once the offspring are born, the octopus mother will die of overwork, so after the birth of the little octopus, there is no one to teach, the experience learned by the mother in her life can not be passed down, the octopus has to start again, no matter what innovations are found in front, all are invalid, there is no archive of the game How do you pass the level, plus the octopus life expectancy is only a few years, there is not enough time to develop civilization from scratch, Therefore, after so many years, octopuses are still inferior animals, in fact, if humans are caught in such a curse, it is estimated that civilization will not be able to develop, and may also have to go back to ancient times.
Archiving is important
The biggest advantages of octopus:
Seeing this, I don't know if you know what the biggest advantage of octopus is? Yes, many people should have guessed that the biggest advantage of octopus is: rich nutrition and good taste!
Octopus is the most evolved mollusk, their muscle fiber is very fine, only one-tenth the diameter of the fish, the content of collagen in the strong connective tissue is 3-5 times that of the fish, which not only brings strong and powerful muscles to the octopus, but also creates the strong taste of octopus meat, and the meat taste is strong and crisp, suitable for stewing and frying sauce and many other cooking methods.
Octopus balls
The familiar octopus balls, granular octopus meat is very powerful Q bomb, in the soft glutinous flour is simply a clear stream, like a pearl in milk tea, endowed with the soul, simply refreshing! Of course, just like most of the wives in the cake do not have wives, the octopus balls you buy outside do not guarantee that there are really octopuses inside!
Octopus in hot sauce
Octopus to make braised or chili flavor does not need to be fantastic, a boneless, soft sticky octopus, just like this in the hot sauce tumbling, constantly absorbing the delicious taste of the hot sauce, a bite down, the taste of the bounce at the same time wrapped in the fresh flavor of the hot sauce, simply not too delicious!
Teppanyaki squid
Hundreds of millions of years of evolution, from the vicious appearance of the sea overlord, to today's household food, thanks to the octopus family for so many years of great efforts, they have finally become our favorite taste, while three hearts, 2 sets of memory system octopus also tells us with personal experience: "three hearts and two memories" is not a good end!
Emma! What a fragrance!
fragrant!
