The knowledge of eight animals is beyond many people's imagination.

The knowledge of eight animals is beyond many people's imagination.

1, the bear runs faster than the horse.

If someone asks you, which is faster, a bear or a horse? I believe I will definitely answer that horses are faster. After all, in the impression of many people, horses have always been the representative of speed, but the real situation may be beyond your imagination. According to the research of scientists, the average speed of horses is about 48 kilometers per hour, while that of bears is about 56 kilometers per hour. Therefore, compared with speed, bears are undoubtedly faster. Of course, although bears are fast, their endurance is much worse than that of horses.

Cows are more dangerous than sharks.

Whether in movies or in reality, people are afraid of sharks, and they think sharks are one of the most dangerous animals in the world. There is no denying that sharks are indeed marine beasts, very fierce, but from the perspective of the proportion of people injured every year, sharks are not dangerous at all, because some researchers have found that the probability of human being being bitten by cattle is 20 times greater than that of being bitten by sharks. The reason is simple, the cow looks very docile and naive. Many people will let their guard down when they touch them. In fact, cows are sometimes very irritable and very hurtful. Judging from the injury rate, it is obvious that cows are more dangerous than sharks.

An elephant can recognize itself in the mirror.

The researchers report that elephants can recognize themselves in the mirror, which is also an animal known to have this self-awareness except apes and dolphins. During the experiment, Asian elephants demonstrated their self-awareness ability by exploring the mirror placed in front of them.

They will check behind the mirror, as if to make sure that the other elephant is not at the other end. The researchers put two X marks on each elephant's cheek, one is white and the other is invisible. When these elephants look in the mirror, they always use their long noses to touch the white X mark instead of being invisible. This experiment also proves that elephants can recognize themselves in the mirror, which sounds amazing!

Jaguar has the strongest bite force among all cats.

Compared with its size, the bite force of jaguar is the strongest among all cats, because according to the research of experts from the University of South Carolina, the bite force of jaguar reaches 2000 pounds, while that of African lion is only 69 1 pound, and that of Bengal tiger is about 1050 pounds.

It can be seen that the smallest jaguar has the strongest bite force among cats. Jaguars' teeth can easily pierce the skull and brain, which means they can also pierce the hard shell of turtles. For animals like crocodiles, it is a complete spike, so we often see videos of jaguars eating crocodiles in the animal world.

Pigeons can remember people's faces.

If you hit a pigeon, they will probably remember you and know that they will avoid you next time. At the same time, even untrained wild pigeons can recognize faces and will not be confused by changing clothes. In the past, some zoologists only focused on the perception ability of pigeons trained in laboratory environment, but new research began to test untrained wild pigeons.

6. Giraffes use infrasound waves to communicate.

Infrasound communication means that giraffes talk to each other with very low-pitched and very low-frequency sounds, which can hardly be heard by our ears. Surprisingly, these animals can use this technology to communicate with similar animals several kilometers away.

7. Newts can regenerate any part of the body.

Cute-looking salamanders have "super powers" that other animals don't have. When their body organs are damaged, such as feet, legs, arms, tails and even parts of the heart and brain, they can regenerate. There is no problem at all. Why do salamanders have such regenerative ability?

8. Dung beetles use the Milky Way to tell their directions.

Although it looks small, dung beetles can use the milky way to tell their directions. In 2009, a group of researchers from South Africa brought some dung beetles to the planetarium in Johannesburg for an experiment. During the day, dung beetles can navigate by polarized light patterns around the sun and walk in a straight line.
