What is the way animals predict the weather?

The following are the contents of abnormal animal behavior and weather changes, which I hope will be useful to you: \x0dl, pig. "the pig bites the grass, and the cold wave comes." "pigs build nests, and heavy snow is falling." This is because the pig's nose and mouth are hairless and are particularly sensitive to cold. Before the cold wave came, it had the foresight to grab grass and build a nest. When the weather is a little cold, it will stick its mouth into the grass, and when it is colder. This is a harbinger of a cold wave. \x0d2。 Dogs. It will rain if the dog soaks in the water. Because dogs don't have sweat glands, they can't rely on pores to dissipate heat in summer, so they can only keep constant temperature by opening their mouths and pulling their tongues to dissipate heat. When their mouths and tongues are useless, they will jump into ponds or streams and soak in water to help dissipate heat. Therefore, it is found that "the dog is soaked in water" indicates that it will rain. The exhaled hot air is used to warm the navel, which indicates that a cold wave is coming. \x0d3, toad. Toad is also an "expert" in prediction. Its physiological structure is special, and its lungs are like football, and its breathing power is not great. It is impossible to get enough oxygen only by breathing in such lungs. Therefore, in addition to breathing with lungs, epileptic toads have to rely on their skin to help them breathe. Breathing through the skin is conditional, that is, to keep it constant. Oxygen in the air first dissolves in the mucus of the skin and then enters the blood through the skin. If the skin is dry, the skin can't breathe and it's hard to live. So it is afraid of strong light and dry weather, so it hides in the dark during the day and comes out for food at night. Before the rainstorm (about 1 day), the air humidity is high, and it also comes out during the day. This abnormal performance is just right. It will rain. " \x0d4。 Fish live by breathing oxygen dissolved in water. On sunny days, when the air pressure is high and there is a lot of oxygen dissolved in the water, it quietly sinks to the bottom of the water; Before the rain, the air pressure was low, and the oxygen in the deep water was greatly reduced, so the fish floated to the surface to breathe, so there was a saying that "the fish dived and it was going to rain". \x0d5, swallow. There is a folk saying that "swallows fly low and it will rain". This is because swallows eat insects. When it rains, there is a lot of water vapor in the air, which makes the wings of some insects wet, just like the plane is too heavy to fly. When the weather turns rainy, the air pressure will become lower, the water vapor in the air will increase, and some insects in the soil will crawl out of the ground. When they swallow, they fly very low to catch insects to eat. \x0d6。 Snakes. Most snakes hide in caves during the day and go out for food, water, bathing and molting at night. However, when the weather is particularly humid and sultry, they will be forced out of the hole. So a snake coming out of the hole during the day is a sign of rain, especially. It will rain in a day or two. It is a verification of "the big snake comes out of the hole and the heavy rain knocks" and "the snake gallery, the rain is coming". \x0d7。 Chicken. "The chicken stays late, and it's rainy again". Chicken has no sweat glands and sebaceous glands, so it is very afraid of heat because of its insufficient heat dissipation ability. It is suitable for adult chickens at 20℃. When it exceeds 30℃, it is often necessary to open your mouth and extend your wings to help dissipate heat. When there is more water in the air, the chicken nest will be wet and the chicken manure will give off an unpleasant smell. Therefore, chickens will not return to their nests. \x0d8。 Mosquitoes bite people indiscriminately, and it will rain soon; Mosquito bites badly and it rained for three days. \x0d9。 Ants are very sensitive to air pressure, temperature and humidity. If they build nests,

It is 2-3 cm or 4-5 cm high. It is predicted that there will be light rain or heavy rain respectively, and it will definitely rain in 2-3 days. Before it rains,

1\x0d hours, they closed the hole to prevent irrigation; Open a ventilation hole in the high place, and wait until the rain clears before opening the hole. \x0d The loach comes out of the water, swallows fly low and ants climb trees, all of which indicate that it will rain soon. \x0d nursery rhymes: \ x0d The animal world is really wonderful, and it can also predict rain. It will rain when ants move, it will rain when small fish fly upstream, it will rain when swallows fly low, and it will rain when dragonflies fly low. It's raining hard.
