How can a frog croak

On rainy days, the frogs will croak very loudly. Especially when it is about to rain, the croaking of frogs comes and goes, and it gets louder and louder, as if it is a concert.

Frogs don't like to live in environments that are too cold, too hot or too dry, they prefer cool and damp places, so when it rains, it is really a joy for frogs. Especially after a period of sunny and dry days, when it is about to rain, because the air pressure drops, the humidity increases, and the moisture in the air increases, the frog's ** is fully moistened, so it becomes active.

At the same time, during the rainy season, many insects breed in large numbers at this time, and these insects are the best food for frogs. At this time, the frog has just passed the cold and dry winter, and needs to hunt a lot of insects to recover its strength. When there is good food and a good environment, the frogs can't help but sing loudly; Taking this opportunity, male and female frogs also mate and breed their offspring by the water's edge.

Summer nights are scorching hot. In the fields, the cries of frogs can be heard: "quack-quack-quack", "quack-quack-quack", and this animal chorus often reverberates in the night sky all night long.

Frogs are amphibians, that is, they can live both in water and on land. However, tadpoles that have not yet turned into frogs cannot do without water because they breathe with gills like fish. As tadpoles grow into frogs, they slowly get used to breathing with their lungs, so that they can live on land.

Although frogs are amphibious animals, they seem to prefer life in the water. We can often see frogs jumping into the water at the water's edge for a while, and then jumping on the shore or on the lotus leaf. At the very least, frogs love humid environments.

Therefore, every time before the rain, the humidity in the air becomes higher and higher, and at this time, the frogs in the fields will "happy" to bark. When the rain falls, the frogs in the pond jump up and down happily, and they are busy.

It's for singing. The frog has a bulging thing in its mouth that makes sounds. It loves to sing loudly on rainy days in the summer, and in the hot summer, the frogs generally hide in the grass, occasionally calling a few times, and the time is also very short.

If one of them calls, the one next to him will also call a few times, as if they are singing. The cries of frogs are happiest after heavy rain. Often, dozens, if not hundreds, of frogs croaked endlessly, and the sound could be heard for miles away.

It is produced by the vibration of the air in the frog's vocal sac and is transmitted into the ear.

The smallest frog is only 5 centimeters, which is equivalent to a person's thumb length, and the large one is 30 centimeters (more than a foot long), the pupils are horizontal, smooth, the tip of the tongue is bifurcated, the tongue is heel in the front of the mouth, and it is long back into the mouth upside down, and it can suddenly turn out to catch insects. There are three eyelids, one of which is clear and used to protect the eyes in water, and the other two upper and lower eyelids are ordinary. There are two vocal sacs on either side of the head that can resonate and amplify the call.

One is to attract the opposite sex and reproduce offspring.

Two, it's the instinct of a frog.

Spring is coming; It's hot and humid, and it's going to rain; It can also be courtship.

It does this by filling up the gills and then releasing them.

One is to attract the opposite sex and reproduce offspring.

Two, it's the instinct of a frog.

This is because frogs prefer cold, moist places, and many insects come out during the rainy season, so frogs can hunt at this time, so they are all active. Because they like cold and damp environments, especially in the rainy season, when the temperature in the air increases, they like to run to the land and let the rain wet their **, so on rainy days we can always hear the chirping of frogs. Another very important reason why frogs like to come out on rainy days is that there are always many insects that like to breed during the rainy season.

These insects then attract frogs to hunt. At this time, the frogs have gone through a cold and dry winter, and they are hungry and need a lot of food to replenish their lack of physical strength. The rainy season attracts many insects to breed, providing a great opportunity for frogs to hunt.

In addition, the rainy season is also ideal for frogs to breed offspring.

Frogs like humidity and know that a rainstorm is coming before it rains, and the humidity in the air is particularly high, and the water vapor content is also very high. At this time, the frog can absorb more oxygen through the wet **, because it feels very comfortable, it becomes excited and active, so it is very happy and loud.

Hello! The frog is an amphibian, but it prefers to live in water. Frogs don't like environments that are too cold, too hot, or dry, and very much like humid places, so they will croak especially loudly when it rains.

Especially after a period of sunny and hot days, when it is about to rain, because the air pressure is particularly low and the humidity increases, the water vapor in the air increases, and the frog's ** gets moistened.

In the summer, many insects breed in large numbers and are the best food for frogs. Under the conditions of good food and good environment, the cries of frogs come and go, and male and female frogs also mate and reproduce their offspring at the water's edge, and soon we will see black tadpoles.

Summer is the breeding season for frogs, so at this time it will attract female frogs by calling, and after the female frogs hear the call, they will rush from all over the place to find their ideal mate, I have to say, this is also one of the wisdom of animals in nature.

After the rain, there is plenty of water, which is suitable for spawning and mating signals.

The croaking of the frog is: quack, quack. Frogs have a call, a "croaking" sound.

They will croak when driving away frogs that invade their territory, when courting, and when they are hurt and cry for help. They can communicate through sound, using different frequencies to express different meanings.

Frog calls are regularFrogs croak, especially in the rainy summer months, frogs are very prone to croaking. This is because the air at this time is relatively humid, and the frogs' ** will be more humid, and their breathing will be smoother. At this time, they are more active and louder.

Frogs also make loud calls during the breeding season in March and April every year, when they make calls to attract the attention of frogs of the opposite sex.

Frogs do not rely on their vocal cords to make sounds, but by puffing up their gills and then releasing them. There are two main reasons why frogs croak at night, one is the frog's instinct, and the other is to attract the opposite sex and thus reproduce the next generation.

Frog chirping is a courtship behavior. During breeding, frogs usually gather in a common area and then chirp continuously and loudly to attract the opposite sex and achieve the purpose of pairing.

Frogs generally come from ponds and rice paddies because these places are moist and easy to breed mosquitoes, which is suitable for frogs to survive. The reason why some rural frogs croak is because they attract the opposite sex in this way.

Frogs come from lakes because frogs in the countryside eat pests and croak when they eat pests.

Coming from the fields, because there are many ponds in the countryside and there are a lot of weeds, frogs like this environment.
