forecasting technique
1. The marine librarian puts shells with German and Arabic flags in glass jars. Unlike the shell with the German flag printed on it as soon as possible before the match against England, Squidward Tentacles "Paul" hesitated about the match between Germany and Argentina for "an hour", but finally took out the shell with the German flag printed on it. Paul Squidward Tentacles predicted that Germany would knock out England in one eighth of the time. Paul has been staring at the glass jar with the German flag. It was not until he saw that we were going to take away both glass jars that he finally jumped into the glass jar containing the German flag shell, took it away and swallowed the mussel. A spokesman for the aquarium said that all his actions indicate that Saturday's game will be a very difficult one, and it may be overtime and a penalty shoot-out. But in the end, Germany won. However, the final result surprised everyone, and Germany beat Argentina 4-0. Although the octopus "Paul" currently lives in Germany, the spokesman said that there is no need to worry that it will prefer the present country. Because he was born in Britain, he is a descendant of many generations of immigrants, and his ancestors may also come from Argentina.
scientific explanation
Because of the World Cup, Squidward Tentacles's "Paul" is red and purple. Why did Germans choose octopus instead of crocodiles, sharks, whales or giant salamanders? In fact, rigorous Germans all know that octopus is an extremely intelligent marine animal.
Octopus has a well-developed brain and can distinguish itself in the mirror. It can also walk out of the maze designed by scientists and eat crabs outside the maze. It has three hearts, two memory systems and 500 million neurons in the brain, so it can be called an escape expert. In order to avoid being killed by predators, octopus will escape on two feet in addition to mimicry camouflage and wrist. In the tropical waters of Indonesia, an octopus named Maginettes was photographed. In the face of danger or divers, this octopus will bend and fold six of its eight claws upward to make coconut shells, while the remaining two claws will stand on the bottom of the sea and secretly move backwards, just like a small moving coconut, and escape by retreating. This gesture is very interesting. Another octopus, Akulitus, is about the size of a walnut. It can also walk on two feet, but the other six feet extend outward to simulate the appearance of seaweed. Obviously, the octopus's wrist has no joints, no bones or skeletal muscles, but it did it. Biologists believe that this kind of brachiopod activity of octopus is very unique, and its camouflage "skill" really needs a little "brain". It turns out that octopus has "conceptual thinking" and can solve complex problems by itself. This ability makes it have the ability to "walk" with both feet. Because octopus is considered as the smartest invertebrate, Germans choose octopus to predict the World Cup. In the 20 10 World Cup, Squidward Tentacles's "Paul" only predicted the German game, with five consecutive victories. It turns out that octopus prediction is a trick played by Germans. Some people may ask, why don't other countries use octopus to predict the victory or defeat of their teams? The answer is that the color of the German flag is exactly the color of octopus's favorite food. Stable structural myoglobin is a necessary condition for octopus to survive in the deep sea. Octopus is keen to eat crustaceans such as shrimps and crabs because of astaxanthin. Astaxanthin is the strongest antioxidant and a necessary condition to ensure the structural stability of myoglobin from oxidation. Shrimp and crab are rich in astaxanthin, and the red substance of mature shrimp and crab is astaxanthin. So the rule of the game is that these foods must be in the container covered with the national flag to attract octopus to climb in. The German flag is black, red and Huang San, which is octopus's favorite food color. It is clearly two prawns hiding in the dark. He definitely prefers to attack such targets. The national flag of Australia is Deep Blue+Redmi. Octopus thought the food was too small to choose, so Australia lost. There is not only a red shrimp but also a red crab on the flag of Serbia. Octopus found it more attractive, so it didn't choose Germany, and Germany lost. It stands to reason that Ghana's national flag is similar to that of Germany, but it is precisely because of that five-star that the octopus thought it was impurity or dangerous and chose Germany instead, so Ghana lost to Germany. What about England? An eye-catching Red Cross offended Octopus, but prompted Octopus to choose Germany, and England was defeated. It's Argentina's turn. Without the color that attracts octopus, defeat is inevitable. On July 6th, 2065438+00, Paul predicted that Germany had no chance to face Spain in the semi-final. Because the flag of Spain is three prawns and a crab. As a result, Squidward Tentacles chose Spain. In the vast nature, almost all mollusks are color blind, and most of their eyes have degenerated. Octopus is obviously not color blind. Octopus is rich in cone cells and rod cells, which can distinguish colors sharply. Octopus's eyes are very similar to those of vertebrates, including cornea, lens, iris and retina, which can focus and image. But it is different from vertebrate eyes because it focuses light by adjusting the distance between the lens and retina, while vertebrates focus light by changing the size of the lens. Octopus can recognize the shape, color and texture of objects. Another difference is that octopus's eyes have no blind spots, and its nerve cells are outside the eyeball. [
