When does the frog bark?

Question 1: When will the frog come out of the water? Singing loudly on rainy days in summer is frog's favorite. There is a bulging thing on the frog's mouth that can make a sound. 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. Scientists have found that the frog's chorus is not random, but has certain rules, such as lead chorus, chorus, accompaniment, etc., which are closely coordinated with each other and are veritable chorus. It is speculated that chorus is much better than solo because it contains more information. Chorus is loud and far away, which can attract more female frogs, so frogs often use chorus. Frog chorus is often a courtship activity, like a collective blind date meeting of human beings. Just before spawning, female frogs collectively sent out blind date invitations to attract male frogs to come to the party and hug each other to lay eggs. Interestingly, frogs hug each other but don't mate. The female frog doesn't sell herself, but she has a dry addiction. The male frog urges the female frog to ovulate on her back, and the fertilization of the eggs is only completed in water.

Question 2: When does the frog bark? From an evolutionary point of view, frogs were the first animals to really sing with tapes. Like people, frog's vocal cords are in the throat cavity. When the air passes quickly, the vocal cords vibrate to make a sound. In addition to the vocal cords, the male frog has a pair of external vocal sacs on both sides of his throat, which protrude outward to form two large airbags when singing, making the voice louder. All kinds of frogs have different sounds and tones, and experienced people can tell which frog is barking by the tones it makes. Both female and male frogs croak, but because of the airbag, the croak of male frogs is bigger than that of female frogs. When should I call it a frog? When it is attacked by the enemy, it will make a quick cry. If we press the back of its body or pinch its side with our fingers, it will bark, and it will bark once. Several frogs crowded together. If a frog touches another's back or abdomen, it will also bark. It should also be called when the environmental conditions are particularly suitable, such as summer night, the night before the rain or after the rain, frogs in the field will come and go, as if in chorus. In addition, frogs are also very excited during the breeding season, which is to attract different people to mate.

Question 3: In what month are frogs called summer? In June, July and August, frogs sing in the fields at night.

Question 4: When will the frog croak? Mostly on summer nights. Frogs croak mainly to attract the attention of the opposite sex.

Question 5: Frogs call April, when it gets hot.

Question 6: How do frogs make their mouths have a pair of singing sacs that will inflate and deflate?
