Frog

Frog

Frogs are slimmer and more good at swimming. The neck is inconspicuous and has no ribs. The ulna and radius of the forelimbs heal, and the tibia and fibula of the hind limbs heal, so the claws cannot be flexibly rotated, but the limbs are muscular. The most primitive frogs began to evolve early in the Triassic. Today, the earliest jumping frogs appeared in the Jurassic. Because frogs feed mainly on insects and other invertebrates , they must inhabit the water’s edge. There are about 130 species of frogs in China, and almost all of them are experts at eliminating pests in forests and farmland.

Frog

The frog body can be divided into 3 parts: head, trunk and limbs. Frogs have four toes on their front feet and five toes on their back feet, as well as webbing. On either side of the frog’s head are two small, slightly bulging bags. That’s its eardrum, through which the frog can hear sounds. The frog’s back is green, very smooth, very soft, and has a pattern, and the abdomen is white. You can make it hidden in the grass, it is easier to catch pests, and you can also protect yourself. Its skin can also help it breathe. Its airbags, only male frogs have. Frogs prey on their tongues, which have mucus on their tongues.

Frog

1. head

The frog has a flattened, slightly triangular head and a slightly pointed snout. The mouth is wide, transversely lobed, and consists of an upper and lower jaw. There is an external nostril at the anterior end of the dorsal side of the maxilla, 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 translucent transient membrane. What changes in the position of the eyeball when the eyelids are closed? There is a rounded tympanic membrane behind each eye (the toad has a smaller tympanic membrane. Above the posterior part of the eye and tympanic membrane there is a pair of oval bulges called the posterior glands, or venom glands). The male frog has a pale brown capsule in the inner and posterior corners of the mouth as a vocal sac, which bulges into a bubble when it calls.

Frog

2. Torso cadres

The eardrum is followed by the trunk. The torso of the frog is short and wide, and between the legs at the posterior end of the trunk, there is a small hole on the dorsal side, which is a cloaca hole.

3. limbs

The forelimbs are short and consist of five parts: the upper arm, the forearm, the wrist, the palm, and the fingers. 4 fingers, no webbing between the fingers. During the reproductive season, the male frog has a large protrusion on the inside of the base of the first finger, called a marriage tumor, which is used for hugging. The hind limbs are long and developed, divided into 5 parts: femoral, shin, tarsal, tarsal, and toe. 5 toes with webbing between the toes. There is a stiffer keratinized distance on the inside of the first toe.

Frog

The nerve cells of the frog’s eye retina are divided into five categories, one that only responds to color, and the other four that only respond to a certain feature of the moving target, and can deliver the decomposed feature signals to the visual center of the brain, the ceiling cap. There are four layers of nerve cells on the ceiling cover, the first layer reacts to the contrast of the moving target; the second layer can extract the convex edges of the target; the third layer only sees the edges of the target; and the fourth layer only cares about the light and dark changes of the dark leading edge of the target. These four layers of features are like drawings on four pieces of transparent paper, stacked together, which is a complete image. Thus, in the rapidly flying small animals of various shapes, the frog can immediately identify its favorite flies and moths, and does not react to other flying things or stationary scenes.

Frog

The smallest frog is only 5 centimeters, about the length of a person’s thumb, and the largest is 30 centimeters (more than a foot long), short and broad, with strong hind limbs. The pupils are transverse, the skin is smooth, the tip of the tongue is divided in two, the tongue follows the front of the mouth, and it is upside down and long back into the mouth, which can suddenly turn out to catch the bug. There are three eyelids, one of which is transparent and used to protect the eyes in water, and the other two upper and lower eyelids are ordinary. There are two sacs on either side of the head that resonate and amplify the call. Smaller varieties have a higher frequency of calls.

Frog

Because the skin is bare, it cannot effectively prevent the evaporation of water in the body, so they cannot live without water or a humid environment, afraid of drought and cold. Therefore, most of them live in tropical and temperate rainy areas, and there are very few species distributed in the cold zone.

When I was young, I could only live in the water, and when I grew up, I could live on land. Frogs breathe with their lungs, but can also draw oxygen from the air through their moist skin. The various pigment cells in its skin will also spread or contract with the humidity and temperature, resulting in changes in skin color. Frogs usually inhabit rice paddies, ponds, ditches or grasses along rivers, and sometimes lurk in the water, usually preying at night.

Frog

The aspect of sports predation is: swimming, jumping, and preying with the tongue. Reproductive development is: oviparous, developmental metamorphosis.
Frogs do not survive in all places where there is water, frogs are afraid of the sea, and frogs can easily die in the sea or salty water.

Frog

The frog loves to eat small insects, is good at spotting small insects that move, and its movements when catching insects: a frog is lying in a small dirt pit, its hind legs are curled up on the ground, its front legs are supported, its mouth is open and its face is back, and its stomach is drumming and waiting for something. A mosquito flew over and swung in front of the frog, and the frog’s body jumped upwards violently, its tongue flipped over, and it landed on the ground again. The mosquito was gone, and it sat back as it was, waiting for the next prey to arrive.

Frog

There is a bulging sac next to the frog’s mouth that can make a sound. It is most loved in the summer

On rainy days, frogs usually hide in the grass, occasionally shouting a few times, and the time is short. If there is one call, there will be several calls next to it, as if it is a song. The time when the frogs bark most happily is after the heavy rain. Whenever this happens, there will be dozens or even hundreds of frogs “croaking-croaking” endlessly, and the sound can be heard for miles.

The vocal organ of the frog is the vocal cords. Located above the laryngeal cartilage. Some male frogs also have external vocal sacs that can bulge and vibrate on both sides of the mouth, and the vocal sacs resonate, making the frog’s song majestic and loud after the rain, when you walk to the pond, you will hear the male frogs echoing each other, one after another, merging into a chorus. Scientists pointed out that the frog chorus is not sung indiscriminately, but has certain laws, there are leading singing, chorus, singing in unison, accompanying singing and other forms, close cooperation with each other, is a veritable chorus. It is speculated that the chorus is much superior to solo singing because it contains more information; the chorus is loud and long, and it can attract more female frogs, so frogs often use chorus form.

Frog

Its eyes are bulging, its head is triangular, and its crawling motion is very dull, and you may think it is a bit silly. But as soon as you get closer, you jump into the pond where the duckweed is floating. This jump is 20 times its body length. Then, in the most standard breaststroke position, swim towards the opposite shore.

Frog

In addition to the white belly of the frog, the head and back are yellow-green, and there are some black-brown markings on it. Some have three white marks on their backs. The reason the frog is green is a good camouflage, it is almost the same color as grass in the grass, it can protect itself from being discovered by the enemy. The frog has two round, prominent eyes on its head, a wide and large mouth, and a long tongue. The back of the body is green with dark stripes and the abdomen is white. There are four legs under the body, the front legs are short, the back legs are long, and there are webs between the toes. Frogs are amphibians that can jump on the ground and swim in the water, making a “croaking” sound, and the male’s cry is loud.

Frog

In the spring, frogs lay their eggs on aquatic weeds, and the eggs slowly turn into tadpoles. Tadpoles are black, rounded bodies, with a long tail, tadpoles grow day by day, first growing hind legs, then growing front legs, the tail gradually shortening and degenerating, and finally becoming a frog. Frogs are experts at catching pests, frogs catch pests all by his long and wide tongue, the root of the tongue grows in front of the mouth, the tip of the tongue is backwards, it is also forked, there is a lot of mucus on it, as long as the small flying insects fly by, they jump up violently, open their mouths, quickly extend their long tongues, and eat the pests at once. The frog’s eyes are dull in seeing quiet things, and they are keen in seeing moving things.

Frog

Natural selection, survival of the fittest.
Predators between creatures, natural choices; the ability to survive as the environment changes.
There are many kinds of pigment cells on the skin of frogs: melanocytes with black or brown pigment particles, yellow pigment cells with yellow pigment particles, red pigment cells with red pigment particles, and many iridescent pigment cells with reflective crystal plates.
The skin is composed of two layers: epidermis and dermis. Several pigment cells are all present in the dermis layer, while there are only smaller melanocytes in the epidermis layer, and the color in the eudermis layer can be revealed due to the thinner epidermis layer. When the frog reaches the dark environment, the environmental phenomena perceived by the eyes are transmitted to the middle lobe of the pituitary gland through the nerves, so that it secretes melanin, melanin diffusion, red pigment and yellow pigment contraction, so that red, yellow and yellow fade, melanin is very eye-catching, the frog is dark, the frog body color change, mainly by the dermis layer of the larger melanocytes involved in the activity of the results.
Ambient temperatures and adrenaline can also cause frogs to change “fashion”. The temperature rises, the color becomes lighter; the temperature decreases, and the color becomes darker. At the same time, the body color is light and the heat absorption is less; the body color is dark and the heat absorption is more, which is beneficial for the regulation of their body temperature. If adrenaline is injected into the frog’s body, the body color will become lighter as the blood pressure rises.

Frog

The non-toxic Reticulated Poison Dart Frog (Ranitomeyaimitator) is draped in bright colors and pretends to be its poisonous counterpart. The strawberry poison dart frog’s brightly colored alertness indicates that it has different toxins on its skin. At first glance frogs, you may think that they lack defenses. Its small body, slow movements, thin and lack of shape such as spikes, claws and teeth are often unprepared. In fact, they have a wealth of defense mechanisms to protect them. First of all, many species have good camouflage ability, and their skin color is very close to the nearby environment, making it easy for them to hide in the environment when they are motionless. When in danger, its amazing bouncing power makes them quickly jump into the water to avoid predators.

Frog

Many frogs have a mildly toxic bufotoxin on their surface, making them unpopular with predators. Most toads, on the other hand, have larger toxin-producing glands, called parotoidglands, which are located mainly behind the eyes on both sides of the body, or in other parts of the body. These glands secrete different toxins or mucus that make their skin slippery and unpalatable. If an immediate unpleasant feeling can be generated, the trapper will often terminate their hunting action and allow them to escape; if the effect takes a long time to take effect, it can also reduce the chances of the trapper hunting again. Poisonous frogs, on the other hand, are often draped in bright colors to indicate that they are not suitable for food, an adaptation strategy known as Aposematism. Most of their colors are bright red, orange or yellow with black. Warning colors for some species grow on the abdomen, such as species of the genus Bell Toad. As a result, they will instead face their abdomen upwards when attacked and secrete venom to drive off their enemies. And there are some species that are not inherently toxic, such as the red-backed poison dart frog, which will simulate the skin color of the poisonous species in their area to scare off predators.

Frog

Large toads in a defensive standing position, some frog species, such as poison dart frogs, are particularly toxic. The natives of South America have long known how to extract the venom from these poison dart frogs to make darts for hunting purposes, although only a few species are suitable for this purpose. In addition, some species, the red-backed poison dart frog, a species of eleutherodactylusgaigei, and a species of Leptodactylus (Lithodyteslineatus) that do not themselves produce venom, but they protect themselves by mimicking the skin color of their toxic close relatives in the region. Although some species absorb their toxins by eating such as ants or arthropods, some species, such as the Australian Koro, are able to synthesize these toxic alkaloids on their own, including frog toxins (batrachotoxin) and bufotoxin, which can cause receptor discomfort, hallucinations, epileptic spasms (Epilepticseizure), neurotoxicity and vasoconstriction. Many predators that feed on frogs have adapted to high concentrations of toxins, but other species, such as humans, are completely resistant.

Frog

Some frogs rely on bluffs and tricks to protect themselves. A standing posture like a big toad is to try to frighten the enemy. They inhale air to inflate the body, raise the back of the body and lower the head to create a majestic form. When threatened, the American bullfrog will tilt its head forward but close its eyes. The aim of this gesture is to place the poisonous parotid gland in the clearest position, while other glands on the back begin to ooze toxic secretions and cover the most vulnerable parts of the body. Other strategies include making a harsh sound and using sudden loud noises to scare away predators. The Maitree Frog can make a blasting sound that can sometimes scare off its natural enemy, the Blarina brevicauda. Toads are generally less popular, but are occasionally coveted by hungry snakes such as the Eastern Banded Snake (Thamnophissirtalis). Young American toads crouch down and stay motionless when they encounter a snake that is interested in them. This quiet method of self-preservation often causes snakes to lose their tracks and successfully protect themselves. But if they are sensed by the snake’s head, they will not hesitate to abandon the crouching posture and quickly jump away.

Frog

There are two main categories of animals: frogs and toads. But there is not too strict a distinction between the two animals. In general, toads live mostly on land, so the skin is rougher; frogs are slimmer and more good at swimming. The two bodies are similar in shape, with an inconspicuous neck and no ribs. The ulna and radius of the forelimbs heal, and the tibia and fibula of the hind limbs heal, so the claws cannot be flexibly rotated, but the limbs are muscular.

Frog

Common frogs in farmland include black-spotted frogs, ze frogs, golden-lined frogs, flower-backed toads and so on.

Bullfrogs introduced from Cuba can be regarded as the “giants” of frogs, with a body length of up to 20 cm. Its mooing sound is very similar to the cow’s cry, so it is called bullfrog.

In fact, there are also frogs with large bodies in China, such as the tiger striped frog living in the rice fields of Jiangnan, which is more than 12 centimeters long and sounds like a dog barking.

The spiny frog, also known as the “stone chicken”, which lives in the mountain streams of Jiangnan, has a body length of about 12 centimeters. So how big is the smallest frog in our country? Only slightly larger than broad beans. In early spring and February, flowers bloom on Hainan Island. At this time, the sound of “croaking” can be heard near the rice field during the day. This is one of the smallest frogs – the chickadee is courting. It is only 2.5 centimeters long, and when it sounds, the lower part of the throat will bulge out of a large bubble – the sac. Sometimes, you can also hear a “squeaking” sound coming from among the water and grass, which is a kind of small frog that is not easy to find- the sound of floating frogs. The frog is grey, only 2 cm long, and often floats between aquatic weeds, showing only its head. As soon as there is movement, immediately dive and flee. Don’t look at the small size of these frogs, they are natural enemies of small pests and termites.

Frog

There are about a dozen kinds of tree frogs in China, they are light and thin, have suction cups at the end of their fingers, are good at climbing tall trunks or short bushes, and their body color is consistent with the surrounding environment. The smallest frog in the world is the Nepenthes microhylanepenthicola, which scientists have found in and around the nepenthes rainforest of borneo in the Malay Archipelago. This newly discovered frog, an adult male about the size of a pea. This size makes them difficult to spot. However, it is very fortunate for scientists that this frog loves to bark very much, and it has a loud call.

Frog

Some tree frogs, such as the red-webbed tree frog and the black-webbed tree frog, have wide webbing between their fingers and toes, and can spread and glide from high branches to low places, so they are also called flying frogs. In addition to tree frogs, there are also rain frogs and turbulent frogs. Turbulence frogs are particularly special, preferring to live in turbulent waters and can quickly cross rapids and climb rocks. The tadpole of the turbulent frog is also very peculiar, and it has a suction cup on its abdomen that can be adsorbed on the rocks so as not to be swept away by the rapids. Toads with “beards” are rare frogs unique to China, which were first found in Mount Emei and later found in several southern provinces. This frog has a wide, rounded, flattened snout, and the male has 12-16 cone-shaped black spines on the maxillary margin, so it is called a bearded toad. The function of these “beards” is still being studied. There are many types of frogs, but either one feeds mainly on pests.

Frog

Frogs are amphibians of the order tailless, adults without tails, eggs laid in water, in vitro fertilization, hatched into tadpoles, breathed with gills, after metamorphosis, adults mainly breathe with lungs, combined with skin breathing. Frogs and toads have similar morphological structures, these two categories

There is no too strict distinction between animals, and the skin of the toad is rough. Frogs are slimmer and more good at swimming. Frogs are national third-level protected animals. Adult frogs breathe with lungs and skin, and are able to leave water to live on land. It is the first step for organisms to go from water to land, more advanced than other aquatic organisms, but reproduction is still inseparable from water, and larvae need to undergo metamorphosis in water to grow.

Frog

Tailless, (scientific name: Anura) is an amphibian animal, adults are basically tailless, eggs are generally laid in water, hatched into tadpoles, breathed with gills, after metamorphosis, adults mainly breathe with lungs, but most skin also has partial respiratory function.

Frogs will: blink their eyes when they swallow food;

Frogs belong to: temperate animals;

Respiratory organs of frogs: lungs and skin;

The respiratory organs of the larvae of the frog tadpole: gills;

The frog’s eyes and face are closed: from the bottom up;

The root of the frog’s tongue is in the part of its mouth: at the front of the mouth;

The structure of the frog’s tongue: the frog’s tongue is at the base of the tongue on the outside, the tip of the tongue is inward, and there is mucus on the tongue to facilitate the capture of insects.

The frog’s body is divided into three parts: head, torso and limbs, and the skin is smooth. Eardrums, through which the frog can hear sounds.

The aspect of sports predation is: swimming, jumping, and preying with the tongue.

Reproductive development is: oviparous, metamorphic development [from small tadpoles to change].

Living environment: When you are a child, you can only live in the water, and when you grow up, you can live on land.

Frogs are omnivores, with plant foods accounting for only about 7 percent of the diet; animal foods make up about 93 percent of the diet. From the 60 frogs dissected, it was found that in animal food, the animals that were swallowed involved four phylums, four orders, decath orders, and more than thirty families. Among the 156 predators, insects accounted for 80%, lepidoptera had the most: 11 rice curl leaf worms, 10 rice borers, 7 rice bracts, 10 armyworms, 2 corn borers, 2 cotton red bollworms, 2 ping gray borers, 3 eyebrow mosquito nocturnal moths, and 5 rice eye butterflies. Coleoptera is followed by 5 rice cathode worms, 6 rice weevils, 2 scarab beetles, and 4 ladybugs. They are followed by hemiptera (8 white-backed planthoppers, 7 gray-backed planthoppers, 2 rice black bugs, and 6 brown-backed planthoppers) and diptera (8 rice leafminer flies, 5 Pedicopus mosquitoes, 2 fruit flies, and 3 mosquitoes). Tailless orders are amphibians, adults

Frog

Basically tailless, the eggs are generally laid in water, hatched into tadpoles, breathed with gills, metamorphosed, adults mainly breathe with lungs, but most skin also has partial respiratory function. There are two main categories of animals: frogs and toads.

Frogs are a collective name for amphibian frogs. Commonly known as the frog in the north, the former name of the field chicken, green chicken, sitting fish, salmon, scientific name black spotted frog, is a nationally protected wild animal, from children to the elderly everyone knows. Its population is widely distributed in the plains, hills and mountains of China, but the quality of individuals is the best in the frogs of the northern land, and its dried fallopian product, ground chicken oil, “can also be used as husky oil”.

Frog

The reproductive characteristics of frogs are hermaphroditic, water fertilization, and oviparous. Breeding occurs around mid-to-late April. During reproduction, frogs have a very special phenomenon – hugging pairs. It should be noted that the frog’s hug is not there

Mating is only one part of the reproductive process, and studies have shown that if the male and female frogs are artificially separated (i.e., there is no process of hugging each other), then even during the frog’s reproductive period, the female frogs cannot excrete egg cells. It can be seen that the biological significance of hugging pairs, mainly through hugging pairs, can promote female frogs to ovulate. Frogs generally lay eggs and fertilize in the water, and after the eggs hatch, they become tadpoles, live in the water, and then become juvenile frog landing activities. However, the method of laying eggs of tree frogs is different, and the eggs produced by the spotted tree frog are like a ball of white soap foam, and like a ball of cream, it adheres to the aquatic weeds. The most interesting is the Emei tree frog, which lays its eggs on leaves at the water’s edge, and the eggs develop in the egg blocks, and then fall into the lake and continue to develop. Another example is the melodious piano frog, which will build a mud nest before laying eggs, and then lay eggs in it. Some frogs belonging to tree frogs do not go up trees, but live in water.

Frog

Frogs are distributed all over the world except the Caribbean islands and the Pacific islands, and are rapidly decreasing around the world, mainly due to environmental pollution, as well as climate changes, invasion of alien species, and shrinking habitat due to human expansion. The expansion of human life has led to a continuous decrease in frogs, and frogs are rarely seen in forests and swamps.

Frog

Most species of amphibians have declined on the planet, and the blame for making existing species rapidly endangered lies in many ways, the most important of which is the frequent human activities and the rapid development of global industry, which on the one hand leads to the extinction of species; on the other hand, due to industrial pollution, especially chemical industry pollution, the deterioration of the ecological environment is increasing, resulting in the large-scale destruction of wetlands.

Frog

Recent studies have found that the content of the compound triphenyltin, which is an inhibitor of agricultural fungi, can cause distortion or even death in several frogs, even if it is lower than the concentration in the field.

Triphenyltin, a fungicide, is mainly used to deal with diseases in sugar beets and potatoes, but is sometimes also used in various crops such as onions and rice. This inevitably pollutes the aquatic ecological environment, some directly polluting rice fields, and also polluting rivers and ditches through surface runoff. Because the liquid phase degradation rate of triphenyltin is very slow, it is enriched in water, which causes great toxicity to aquatic organisms, especially the central nervous system of tadpole brains.

Frog

In general, the higher the concentration of fungal inhibitors, the greater the toxicity to organisms. In amphibians, chemicals often cause stunted growth, which in turn makes it difficult to escape predators. This is likely to be the cause of the extinction of frog populations in some areas.

There are other pollutants responsible for declining amphibian populations in more areas, with acid rain being one of the biggest culprits. In fact, almost all amphibian eggs and larvae have a pH of less than 4. 5 can not survive in the water. However, the pH of acid rain is generally 3.5, which can reduce the normal pH in the water of the pond stream to a lethal level. In Canada, Scandinavian countries and Eastern Europe, acid rain has been identified as the cause of the decline in amphibians in ponds and lakes.

Frog

Perhaps the reduction in ozone is the inevitable responsibility for the decline in amphibian populations in larger regions and even globally. The thinning of the Earth’s ozone layer and the rise in ultraviolet radiation will prevent amphibian eggs from hatching into juveniles. Other amphibians most likely to be affected by the increase in ultraviolet radiation are amphibians that live in higher colds and closer to the polar regions, where the ozone layer is the thinnest, and amphibians have to bask in the sun to regulate body temperature, resulting in an increase in radiation exposure and the destruction of DNA molecules.

Frog

Environmental hormones may also be responsible for declining amphibian populations worldwide, and pollutants that decompose from pesticides such as DDT have the potential to severely damage amphibian reproduction, similar to aquatic organisms such as fish and crocodiles. In fact, this environmental hormone has been found to maleize some female tree frogs, as well as other species of male tree frogs, and as a result, these tree frogs are unable to reproduce. This hormonal molecule, which is not easily broken down in the environment, is deposited in the sludge at the bottom of ponds and lakes and swallowed into the abdomen by the larvae of amphibians living at the bottom. This hormone, with a small build-up, takes effect and is extremely easy to drift with the wind, so it poses a global threat wherever it originates.

Frog

The increasingly serious greenhouse effect on the earth not only makes the climate strange changes, but also makes the number of discolored frogs gradually increase, and many places have appeared all kinds of orange, white, and even pink frogs, which is certainly not a joke between nature and humans.

Transparent frog

In June 2014, a pond was discovered in Chofu City, Tokyo, Japan

Blue frog

In August 2014, a light blue frog was exhibited in Kitado City, Yamanashi Prefecture, Japan. Frogs are usually green, and it is possible that only 1 in 100,000 frogs is only blue, which is very rare. The frog was spotted by a 4-year-old child in Yamanashi Prefecture, Mizutani Leaf Rain, helping to harvest rice in the field. The frog is about 2 cm long and has a light blue back.

The children who came to visit said that they had never seen a blue frog, which was very beautiful. According to the analysis of relevant insiders, rain frogs (small frogs) are usually green and may suddenly mutate, fading carotene and thus becoming light blue.

Many malformed frogs found in North America are caused by high levels of vitamin A complexes in living environments, which contain retinoic acid, a hormone that controls several important aspects of the development of vertebrates, and its excess can also lead to reproductive malformations in humans.

In the United States, there are some severely deformed frogs in wetlands close to lakes and rivers, some with only 3 legs, some missing the first two legs, and some with 3 or 4 hind legs. The news has caused shock and close attention from environmental experts and people around the world. In this regard, some people think that it is the ghost of parasites, some think that the culprit is insecticides, and some believe that the destruction of the ozone layer causes too much ultraviolet light pollution of the environment and causes animal deformity. The biggest of these may be caused by water pollution. It can be confirmed that the water source is contaminated by a variety of substances, including special pesticides, heavy metals, chlorides, and of course, other chemicals are not excluded.

Frog

Because frogs are amphibians, they are generally seen as an accurate barometer or indicator of environmental hygiene. When frogs develop, their embryos are directly immersed in water and are more susceptible to teratogens and are therefore more vulnerable. For humans, although their embryos are protected by a variety of factors during development, they can also affect people through the pathway of hormonal frog deformity, and human aberrations may also exist. There is no doubt that it can cause frog deformity and it must also deform people. It’s only a matter of time before this day comes.

Frog

With the continuous evolution of frogs, there are various frightening and grotesque-looking frogs, some of which have frog skin secretion of venom to prevent predators, a kind of tree frog living in the amazon rainforest, known as the poison dart frog, its secretions are used by local Indians to make poison arrows, see blood to seal the throat.

The ancestors of frogs originally lived in water, and later due to changes in the living environment, some rivers and lakes became land, and the ancestors of frogs gradually developed from water to land with changes in the environment, and the changes in the living environment forced the ancestors of frogs to make corresponding “adjustments” to their body organs to adapt to changes in the environment. Some species that can adapt to life on land survive, the motor organs have changed from tails swimming in water to limbs that can move on land and in water, and respiratory organs have changed from gills to lungs. The evolution of frog ancestors from aquatic to terrestrial was not very thorough, and thus manifested itself in the development of frogs’ larval bodies. The difference between tadpoles and frogs is the legacy left by their ancestors.

Frog meat is tender, less fat, low in sugar, rich in protein, carbohydrates, calcium, phosphorus, iron, vitamin A, B vitamins, vitamin C and a variety of hormones.

Frog

Frogs are also medicinal animals that integrate food, health care products and medicines. Edible, is the best green food. Ming Li Shizhen’s “Compendium of Materia Medica” contains: “The southern people eat it, call it a field chicken, and the cloud meat tastes like a chicken.” “The beauty of food”. Medicinal, is the dietary health care products, medicines. According to the “Northeast Animal Medicine”, “frogs are used freshly or in the shade, and can be used in medicine in their entirety”, which has the effect of “reducing swelling and detoxification and cough”, and can “cure edema and asthma, measles, menorrhagia, etc.” Its adult gallbladder, liver, brain, and skin can be used for medicinal purposes. Juvenile tadpoles have a life-prolonging effect. After investigation, the medicinal use of frogs, “Materia Medica”, “Compendium of Materia Medica”, “Compendium of Materia Medica”, “Nihuazi Materia Medica”, “Animal Materia Medica”, “Derivation of Materia Medica”, “Seeking Truth from Materia Medica”, “Summary of Materia Medica”, “Daily Materia Medica”, “Land Materia Medica”, “Dictionary of Chinese Medicine”, “Dictionary of Chinese Medicine”, “Dictionary of Chinese Medicine”, “Encyclopedia of Practical Chinese Herbal Medicine”, “Chinese Animal Medicine”, “Chinese Medicinal Animals”, “Jilin Chinese Herbal Medicine”, “Jilin Chinese Herbal Medicine”, “Chinese Medicinal Animals”, “Chinese Medicinal Animals”, “Chinese Herbal Medicine”, ” It is recorded in more than 20 chinese medicine books, such as the Compilation of Medicinal Materials, the Compendium of Modern Materia Medica, and the Collection of Modern Research on Chinese Medicine. The results of modern studies show that fresh frogs are each 100 grams, containing 87 grams of water, 11.9 grams of protein, 0.3 grams of fat, 0.2 grams of carbohydrates, 0.6 grams of ash, 22 mg of calcium, 159 mg of phosphorus, 1.3 mg of iron, 0.44 mg of thiamine, 0.22 mg of riboflavin, and 2.1 mg of niacin.

Frog

Frogs also contain peptides, vitamins, biological hormones, enzymes and moisturizing factors. Professor Taylor, an international rescue organization for amphibians, said: “Frogs can benefit human beings because their outer skins contain compounds that deal with disease, including antibacterial and antiviral substances, and the drugs extracted from frog skins are ‘almost unlimited’, ‘frogs can provide a large number of new drugs’, they are like ‘pharmacies that jump on the streets'”.

Frog

Medicinal effect: Frog meat is cool, sweet taste, with heat and detoxification, swelling and pain relief, kidney tonic, nourishing the lungs and nourishing the kidneys.

Modern medicine proves that frog meat not only has no special nutrition, but eating too much will affect human health and even infect parasitic diseases. Frogs generally live in farmland, crops use more fertilizers and pesticides, the amount of pesticides increased and applied unreasonablely, so that pests produce resistance, resistance to promote the use of pesticides continues to increase, frogs often swallow pests with fertilizers, pesticides and water sources

Pesticides accumulate in the frog’s body, and if people eat them, pesticide residues enter the human body. Pesticide residues will poison the human body through the “food chain”, forming chronic pesticide poisoning, resulting in various cancers and tumors; and may even lead to congenital malformations in infants.

Frogs are also hosts of a variety of parasitic virus bacteria, and cooking cannot be completely eliminated. Among them, there are two kinds of human health, spinosarcoma nematode, Taenia mansonii and double slotted larvae. People eat the meat of frogs with these insects, and the worm may molt in the human body into a third stage larvae or early adult, causing disease in the human body. Parasites swim in the human body, causing damage to all parts of the body, especially skin and muscle tissue; when wandering, the site where the parasite stays forms abscess nodules; when wandering in the nervous system, it can cause inflammation of the brain and spinal cord. There have been cases of death in the country caused by eosinophilic inflammation of the cerebrospinal cord. Double-slot worms are very tenacious, even if the frog meat is fried and fried, it is not easy to be killed. Double groove crickets will parasitize in the subcutaneous tissues of the abdomen, wrists, legs and stomachs of people, and the parasitic double slotted crickets will cause the surrounding human cell tissue to produce a kind of mucus, the face will appear puffy, and the abscess will be serious. Once this double groove worm invades the human eyeball, it causes various inflammations, which can easily lead to corneal ulcers, vision loss, and even eye blindness. It also parasitizes in the eyes, around the kidneys, etc.

After people eat excessive amounts of frog meat, they are prone to food poisoning. This can be harmful to human health.
