How do frogs catch pests, and what do frogs catch insects

When the frog sees the insect coming, it usually jumps up and catches it, of course, sometimes it can't reach it, and it has to stick its long tongue out.

The frog body can be divided into a head, trunk, and limbs3

Part. Frogs have four toes on their front feet and five toes on their hind feet, as well as webbed. On either side of the frog's head are two small bags that bulge slightly.

That's its eardrum, through which the frog can hear sounds. The frog's back is green, smooth, soft, and patterned, and its belly is white. You can hide it in the grass, make it easier to catch pests, and you can also protect yourself.

It's also helps it breathe. Its air sacs are only available to male frogs. Frogs prey on their tongues, which have mucus on their tongues.

Head. The frog has a flattened, slightly triangular head and a slightly pointed snout. The mouth is broad, transversely lobed, and consists of an upper and lower jaw. There is a dorsal anterior aspect of the maxilla.

One is the outer nostril, and the outer edge of the outer nostril has a nasal flap. The eyes are large and prominent, born on the left and right sides of the head, with upper and lower eyelids; The inner side of the lower eyelid has a semi-transparent transient membrane. When the eyelids are closed, there is a round eardrum behind each eye (toads have smaller eardrums.)

In the posterior upper part of the eye and tympanic membrane there are a pair of oval bulges called the posterior auricular glands, i.e., the poison glands). There is a light brown membranous fold behind the mouth corner of the male frog as a vocal sac, which bulges into a bubble when chirping.

Torso. The tympanic membrane is followed by the trunk. The trunk of the frog is short and wide, and there is a small hole on the dorsal side between the legs at the back end of the trunk, which is the cloaca foramen.

Limbs. The forelimbs are short and consist of five parts: upper arm, forearm, wrist, palm, and fingers. Four fingers, no webbing between the fingers.

During the reproductive season, there is a bulging protrusion on the inside of the base of the first finger of the male frog, which is called a marital tumor, which is used for holding the right. The hind limbs are long and well-developed, and are divided into five parts: thigh, tibia, tarsus, plantar and toe. Five toes, webbed between the toes.

There is a stiffer keratinized distance on the inside of the first toe.

Frog predation. The tongue of a frog is different from that of a human in that the base of the tongue grows at the top of the bottom of the mouth, but the tongue extends into the mouth, which is long and wide, and the tip is bifurcated like a polyp and covered with mucus. When the insect flies, it quickly turns its tongue out, sticks the insect and rolls it into the mouth.

Frogs feed on insects, but also on snails, snails, shrimps, and fish. The vast majority of the insects eaten are agricultural pests. It is estimated that a single frog can prey on 70 bugs a day and eliminate 15,000 pests a year.

The frog is an animal that is beneficial to agriculture and should be promoted for conservation. In late autumn, when the weather gets colder, frogs hibernate under the water or in burrows, and return to the water to breed when the weather warms up the following spring. During the breeding period, many males often gather in a common area and chirp loudly and continuously, which is called "toad noisy pit".

In fact, this is a kind of courtship behavior of male frogs, which attracts the opposite sex by chirping and forming mates.

According to the topic, we cannot come up with a specific number, because the number of pests caught by frogs will be affected by many factors, such as the species of frogs, the number and species of pests, the environment, etc. Therefore, we need more information to come up with an answer.

Frogs not only eat pests, but also have the potential to help us fight the flu. Researchers in the U.S. and India said they found a component in the mucus of some frogs that could be used to kill the H1 influenza virus.

Researchers report in the new issue of the American journal Immunity that host defense peptides secreted by frogs** were previously known to defend against bacterial infections, but they found 32 host defense peptides from a colorful, tennis-ball-sized frog in southern India, and found that four of them also had antiviral abilities.

To maintain the ecological balance, it can be used as an experimental product for humans to do blood research, there is a kind of frog body transparent, humans can observe in detail the changes in some organs in the body of frogs after taking the drug, so as to understand the *** of this drug and so on.

In addition to contributing a lot to agricultural production, frogs also have other uses. Although the toad has an ugly and smelly appearance, it can secrete a kind of venom due to its ** root nodules. This venom can be used to make toad crisp, which is the raw material of many medicines, and is said to have the effects of hemostasis, anti-inflammatory, detoxification, and swelling.
