Frogs croak and it's raining. Why can frogs predict the coming rain?

Frog's skin and organs are very sensitive to weather changes. Before every storm comes, they will gather together and cry loudly. Especially before the thunderstorm weather comes in summer, frogs gather more and more, and their calls become louder and denser. Repeated observation shows that frogs gather in groups, and their calls are loud and close, which always appear before the rainstorm, so they can be used to predict the weather. Courtship only happens in the rainy season, and only when you scream. Therefore, when frogs croak, it will rain, and when it rains, frogs croak.

Frog's skin and organs are very sensitive to weather changes. Every time before it rains, the humidity in the air becomes higher and higher. At this time, the frogs in the field will bark happily. When the rain falls, the frogs in the pond jump up and down happily and are busy. There is a bulging thing on the frog's mouth that can make a sound. It likes to sing loudly on rainy days in summer. In hot summer, frogs usually hide in the grass and occasionally make short calls.

If there is a cry, the people next to them will scream a few times, as if singing to each other. Frogs are happiest after the heavy rain. At this time, there will be dozens or even hundreds of frogs croaking endlessly, and the sound can be heard for miles away. ?

Vocal cords are the vocal organs of frogs. Located above hilar cartilage. On both sides of some male frogs' squabbles, there are external sound sacs that can expand and vibrate, and the sound sacs produce * * * sounds, which make the frogs' songs magnificent and loud. When you walk to the pond after the rain, you will hear the cries of male frogs echoing each other, one after another, forming a chorus.
