What is the natural phenomenon that animals predict the weather?

In nature, some animals constantly adapt to changes in the environment in order to survive. In the long-term evolution process, they are sensitive to some weather changes. The following are some common natural phenomena that animals predict the weather:

-Spiders weave webs: As the saying goes, "Spiders weave webs, and the rain clears up." On rainy days, if the air pressure increases, the humidity decreases and insects fly high, spiders will open their nets to prey on insects, which indicates that the weather will clear up. On the contrary, the spider closes its net, which indicates that it will rain.

-Frog shouted: When the air is dry, the moisture in frog skin evaporates quickly, and naturally stays in the water to keep the skin moist; Frogs will jump out of the water in wet and rainy seasons, including when the air humidity is high before rain.

-Bees don't leave their nests: Before it rains, bees often get thin water droplets on their wings, gaining weight and making it difficult to fly, so they have to stay in the hive.

-Tortoise "sweating": When it rains, the air humidity is high, the turtle shell is cold, and water vapor condenses on it, as if sweating.

-Earthworms unearthed: Earthworms originally breathed oxygen through gaps in the soil. Because the humidity is too high, the soil particles stick together and can't breathe oxygen through the gaps in the soil, so they go to the ground to breathe.

-Mimosa: If Mimosa closes quickly and opens slowly, it indicates that the weather will be fine; On the contrary, if it closes slowly and opens quickly, it means that the weather will turn rainy.

-Swallows fly low: Since ancient times, there has been a folk proverb that "swallows fly low and heavy rain is coming".

-Fish come out of the water: when it rains, the weather is dreary and sultry, which reduces the amount of dissolved oxygen in the water, so the fish float to the top of the water and even breathe on the surface.

-the loach turns over: it is known as the "barometer". On sunny days, it stays motionless under the water. Before the storm comes, it will fly up and down in the water very violently. It may rain soon.
