Teacher, did the animals and plants change before it rained?

If the domestic goldfish suddenly floats to the surface from the bottom of the fish tank, it seems to be inhaling. This means that it is going to rain. The reasons are as follows: fish need to absorb oxygen from the water. When it rains, the air pressure is low, and the amount of air in the water decreases. If the fish can't stand it, they float.

2. Swallows fly low:

Swallows are forced to fly low because their important food is insects in the air. Because it's going to rain, the wings of insects have already felt the humidity of the air and can't fly high. Swallows that prey on insects have to fly low, which is a clear sign of rain.

3, the chicken does not enter the nest:

Chickens are afraid of heat because they have no sweat glands. It's usually sultry before it rains. At this time, even if you feel them go in, they will not move. Stay in a cool place. Especially in summer, if this happens, there will be thunderstorms in all likelihood.

4, toad out of the hole:

Toads are afraid to do so. Because their skin is very fragile. So in general, we only see toads croaking at night. If it's going to rain, toad will have activities if he feels the air is humid. As the saying goes, "When a toad goes out, it will rain".

5, ants move:

Ants have the ability to feel rain, because they are the animals closest to the ground. Generally, ants can know whether it has rained recently by changing the humidity in the air. Then move the nest from low to high. Ants are very busy before it rains, so you can observe them if you are interested.

Extended data

For other animals, signs of rain:

1, mammals: dogs and cats

"Dogs wash their faces, cats eat grass, and it rains in less than three days"; "Dogs bite grass, cats bite grass and rain"; "The dog is lying in a pile of ash, and it is raining." In addition, if the cat buries its nose in fur, it also indicates that there is a cold current coming from the north.

2. Birds: Magpie

Magpies are auspicious birds in our country. According to scholars' research, the degree of magpie nesting is related to the annual rainfall. For example, magpies nest in high places, and it rains a lot all the year round. If magpies nest in low-lying areas, it means that there is little rain all the year round.

3. Reptiles: turtles

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 turtle shell is dry and the lines are clear, which indicates that it will not rain.

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.
