Frogs are expert at preying on insects, why do frogs blink when they devour

The frog's blinking when swallowing is caused by its own mouth structure, which is only a small film between the mouth and the eyeball.

1. The movement of the frog's mouth when swallowing food.

Frogs are a kind of beneficial insect for humans, and their usual food is mainly some small insects, generally speaking, frogs will like to squat on the edge of the pond, staring intently at all kinds of small insects flying around, and then suddenly stick out their tongues to eat the insects. In the process of swallowing food, because there is only a thin film between the eyeball and the mouth, every time it starts to swallow food, it will affect the eyeball, and the eye muscles will contract, so the blinking action will occur naturally.

Second, the number of blinks is related to the size of the food.

If one observes closely, they will see that the frog blinks very quickly when it swallows food. For example, some small insects, the frog basically swallows the small insect quickly in the blink of an eye, if it is a relatively large collision, if the frog needs to prick its eyes several times before it can swallow the insect. Only after the frog has eaten its food completely will it stop blinking.

If you are lucky enough to see the frog swallowing relatively large food, you will find that the frog is blinking constantly, and sometimes even staying in one place for a long time, in order to swallow the food.

3. The body structure of the frog.

In addition, the frog blinks when swallowing, in fact, it has a certain relationship with the body structure, the frog has no bones under the eye socket, and there are no other bones such as the nose between the frog's eyes and the mouth, only a thin film. From a human point of view, the frog's head and neck are basically connected to the body, and food only enters the body through a small pipe, and the entire mouth can be enlarged until the food is swallowed. In addition, during the process of swallowing food, the frog's eyeballs will also protrude into the mouth, forming a pressure that pushes the food towards the mouth and esophagus, helping it to swallow the food.

It has no bones at the base of its orbit, and is separated only by a thin membrane between its eyeball and its mouth. Every time you swallow food, the frog's eye muscles contract, producing this blinking motion; At the same time, the eyeballs protrude towards the mouth, creating a pressure that pushes food into the esophagus. In this way, the frog often blinks whenever it swallows.

It is to better judge the position of the other party, judge the direction of the other party, and then achieve fast and accurate capture of food.

Because the eye structure of frogs is relatively special, there is no bone under their eye sockets, which causes them to have only a thin film between their eyes and mouth, so when the food in the mouth is swallowed, the eyes will keep blinking, and the action of blinking is also helpful for the frog to swallow food.

The reason why the frog blinks frequently when swallowing is because it has a large mouth, and the frog has no bone support in the eyes and mouth, only a thin layer of skin, when swallowing, it must use the force to push the food into the abdomen, at this time the eye muscles will be pulled, so as to blink unconsciously. Frogs usually keep their eyes on their prey when hunting, and then wait for an opportunity to hunt successfully.

Because frogs have no bones under their eye sockets, swallowing causes the muscles of the eyes to contract. When an insect moves around the frog, the frog jumps up quickly and turns its tongue out.

Frogs are amphibians, they live in the water when they are young, and they can also live on the shore when they grow up, and they mainly feed on insects, and they are also an animal that is more beneficial to humans.

Frogs are amphibians, and they mainly live by preying on various pests in the fields, so frogs are also a beneficial animal for humans.

Personally, I feel that frogs are amphibians, and generally prey on grasses, insects, insects, birds, snakes, etc., to sustain life with these things.

Frogs are amphibians. It mainly feeds on mosquitoes or some field pests.

1.Frogs can become insect catchers mainly because of their tongues, legs, and eyes.

2.Although they also have teeth, they mainly use their tongues to hunt and eat.

3.Their tongues are flexible enough to quickly roll insects into their tongues and swallow them.

4.Moreover, their leg muscles are very developed, which allows them to jump quickly to catch Kunchong macro insects.

5.They also have leaky eyes and are very sensitive to objects in the scattering movement, allowing them to quickly spot bugs.

Search for information on frogs (how frogs catch pests, how many can be caught per year.

A medium black spotted frog eats about 70 insects a day, and can eliminate about 150,000 pests based on predation for 7 months a year; A frog can catch up to more than 260 insects a day, and eliminate more than 40,000 pests a year.

How many pests can a frog catch in a day?

According to research, a relatively small frog eats about 50 insects a day on average, and more than 260 can eat more.

Three frogs catch three pests in three minutes, how many frogs can catch ten pests in ten minutes? Why?

Three will do. Because three frogs catch three pests in three minutes, which means that three frogs catch one pest in an average of one minute. So three can catch ten pests in ten minutes.

How many pests does a frog catch in a day?

How many pests can a frog eat in a day More than 2,400 tons of frogs are eaten a year.

This newspaper, April 14 (reporter Zhang Shangwu, correspondent Yan Huimin Li Li) When agricultural experts came to Tiejiaozui Town, Xiangyin County in early April to conduct an agricultural environment survey, Su Zegao, a grain farmer, chanted without thinking: "The sound of frogs in ten thousand paths is extinguished, and moths are rampant in the fields. ”

Breeding period. Today, the province's agricultural environmental protection experts issued an appeal to the society: protect frogs, do not catch frogs, do not eat frog skins; Save the farmland "guards" and let the Sanxiang fields reproduce the scene of frogs.

According to the statistics of the Food and Agriculture Organization of the United Nations, a medium black spotted frog eats about 70 insects a day, and can eliminate about 150,000 pests based on predation for 7 months a year; A frog can catch up to more than 260 insects a day, and eliminate more than 40,000 pests a year.

Agricultural environmental protection experts said that if there are 400 frogs per mu of paddy field, more than 20,000 pests can be eliminated per burning, and basically no pesticides can be used to kill insects. This can greatly reduce production costs, protect the environment, and green food without pesticides is more popular in the market.

Right now, the biggest threat to frogs comes from insecticides. Farmers use banned and highly toxic pesticides, and frogs are almost extinct in some places. The second biggest threat to frogs comes from people's "appetite".

The frogs, which have disappeared in the fields, have become a delicacy on people's tables. According to a conservative estimate by the provincial agricultural and environmental protection department, more than 2,400 tons of frogs were eaten in our province last year.

This year, the province's agricultural and environmental protection departments will strengthen law enforcement and advocate the use of low-toxicity biological pesticides; In accordance with the relevant regulations, we will crack down on the illegal capture of frogs. Tang Jianchu, director of the provincial agricultural and environmental protection station, said: "This will not be effective in the short term, but we will do our best to protect the frogs." ”
