Animals can predict changes in the weather. Do you know any animals? Why can animals "predict" the weather?

In nature, in order to survive, some animals constantly adapt to environmental changes, and in the long-term evolution process, they have more sensitive response ability to some weather changes. ? Jellyfish can capture the information of the coming storm before 15 hours, and calmly hide their bodies in a safe place. Bioengineers have found that jellyfish have an "ear" that can feel ultrasonic waves. There is a thin rod at the front end, and there is a ball filled with liquid inside, on which a small stone floats, which is in contact with nerve endings. When the balls receive ultrasonic waves, they transmit them to the nerves through pebbles, and jellyfish know that strong winds are coming.

Misgurnus anguillicaudatus is called a barometer. On a sunny day, stay under the water; When the wind and rain come, it will curl up and swim. When it turns over very violently in the water, it may rain soon. ? In the animal kingdom, frogs are called "living barometer", which is caused by the characteristics of frog skin. When the air is dry, the evaporation of skin moisture is accelerated, so frogs need to stay in the water to keep their skin moist; In the wet and rainy season, the skin moisture does not volatilize and jumps out of the water. Therefore, frogs have become a "living barometer" for African aborigines to observe weather changes. As long as the locals see the tree frog climb from the water to the tree, they will do a good job of rain protection.

If you see the ant nest building higher and higher, you have to prepare warm clothes. It may be very cold this winter. ? Newton, a great scientist, once heard a shepherd say it was going to rain, but he doubted it because it was unusually sunny. But in less than half an hour, it began to rain heavily. Newton was surprised and asked for advice. The shepherd pointed to his flock and said that some behaviors of the sheep told him that it was going to rain. A sheep is a hygrometer. If the goat lies under the eaves, it will rain. Sheep jumping on the grass will be sunny.

Siberia also has a "hygrometer" chipmunk. In sunny weather, if chipmunks jump around screaming, dark clouds will soon cover the sky and rain will fall in an instant; If chipmunks bark loudly in the morning, it means there will be bad weather at night. ? Why can animals predict the weather? Everyone may have known since childhood that "ants moving" indicates that it will rain. This is probably the most well-known example of an animal's "predictive" ability.

In addition to ants, the people also summed up many "animal predictions": pigs pick grass in the morning, which means it will rain after 36 hours, and pick grass in the afternoon, which means it will rain after 20 hours; It's late, but the sheep don't go home. They just bow their heads to eat grass and don't like to walk, which indicates that it will rain the next day. In the morning, if there are a large number of bees scrambling to fly out of the nest to collect honey, it means it is sunny today, otherwise it means it will rain. ? Why can animals "predict" the weather? Some reasons are very simple, such as the thin wings of bees, the increase of atmospheric water content and low air pressure in rainy days, and the wings will become soft and heavy when they are wet, so bees are reluctant to leave their nests in rainy days. ?

But the deeper truth is still controversial and explored by the scientific community. For example, before the Indian Ocean tsunami, many animals "fled" in advance, and few people died in the disaster, which made people doubt that they had a sixth sense. However, a lot of research is needed to predict disasters according to animal behavior. In short, the mystery of nature is beyond human imagination, and we still have a lot to learn!

Small knowledge and big vision

The tortoise sweats and takes an umbrella when going out. The turtle's back shell is wet, and the lines on the shell are mixed and dark, which is a sign of rain. There are drops of water on the turtle shell, like sweating. It's going to rain heavily. The dry shell and clear lines indicate that it will not rain in the near future. This is because the turtle is close to the ground and its back is smooth and cool. When warm and humid air moves, water drops will cool and condense on the turtle's back, and it will rain. On the contrary, the air is dry and it won't rain for the time being.
