Which animals can predict the weather and tell them what to do?

As the saying goes, "spiders weave webs, and after the rain, it 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.

2. Frogs shout loudly

When the air is dry, the frog's skin water evaporates faster, so it naturally stays in the water to keep its 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' wings are easily wetted by tiny water drops, which makes them gain weight and make it difficult to fly, so they have to stay in the hive.

4. Ants can move

Before it rains, if the nest is too wet, the ants can't stay here any longer. They have to move to a high and dry place, so it will happen that the ants move before it rains.

5. The tortoise "sweats"

When it's going to rain, the air humidity is high, the turtle shell is cold, and the water vapor condenses on it, as if sweating.

6. Fish probe

Due to the low air pressure, the oxygen content in water is obviously reduced. Small fish can't meet the oxygen needed by the body only by gills, so they must float to the surface and breathe through their mouths.

7. Earthworms unearthed

Earthworms who used to breathe oxygen through soil gaps, because the humidity was too high and the soil particles stuck together, could not breathe oxygen through soil gaps, so they went to the ground to breathe.

8. Swallows fly very low

Before the rain, the air humidity was high, and the wings of insects became heavier because of the water vapor, so they could not fly high. Swallows have to fly very low to catch them.
