The difference between frogs and frogs is as follows:

The frog, also known as the tiger frog, its head grows stout and sturdy, and it is known as the "frog of Asia". The female is larger than the male, the body length can be more than 12 centimeters, weight 250 to 500 grams. The skin is rough, with dark irregular markings on the head and side of the body. The back is yellowish green and slightly brown, with a dozen rows of longitudinally arranged skin ribs, skin ribs scattered between small warts. The ventral surface is white, also with irregular markings, and there are grayish-brown spots on the pharynx and thorax. The anterior and posterior limbs have transverse spots. These spots are so named because they look slightly like tiger skin. The toes are pointed and rounded, with full webbing between them. The forelimbs are stout, and the finger pads are developed and gray. The male frog has a pair of external vocal sacs. It has been listed as a national key animal for protection.

Frogs (Frogs) belong to the phylum Chordata, Amphibia, Caudipterygium, Frogs, amphibians, adults have no tails, the eggs are laid in the water, fertilized in vitro, hatch into tadpoles, and they breathe with gills, and after the mutation, the adults mainly breathe with the lungs, and also breathe with the skin. Most frogs reproduce through in vitro fertilization, where the fertilized eggs hatch outside the mother's body into tadpoles. Only 10 to 12 species of frogs in the world have evolved to fertilize their eggs internally, and some of them expel the fertilized eggs from their bodies to hatch into tadpoles. However, frogs are specifically referred to in zoological terms as black-spotted side-pleated frogs. Frogs have always been considered oviparous, but scientists have discovered that a frog living in the rainforests of Sulawesi, Indonesia, is capable of laying tadpoles. The frog is the only one of more than 6,000 species of frog in the world that can "lay tadpoles.

The frogs are slim and mostly good swimmers. The neck is inconspicuous, with no ribs. The ulna and radius of the front limbs are fused, and the tibia and fibula of the hind limbs are fused, so the claws can not rotate flexibly, but the limbs are well-muscled. The most primitive frogs began to evolve early in the Triassic period. The earliest present-day frogs with jumping movements appeared in the Jurassic period. Because frogs feed mainly on insects and other invertebrates, they must live near water. There are about 130 species of frogs in China, and almost all of them are capable of destroying pests in forests and farmland.

Frogs can be eaten, and their effects are as follows:

1. Nutritional composition

The meat of frogs is tender, with little fat and low sugar, and it is rich in proteins, carbohydrates, calcium, phosphorus, iron, Vitamin A, B vitamins, Vitamin C, and a variety of hormones.

2, medicinal value

Frog is also a set of food, health care products, medicines in one of the medicinal animals. Eating, is the best green food. Ming Li Shizhen "Compendium of Materia Medica" contains: "South people eat it, called the field chicken, the cloud meat flavor such as chicken also". "Food is the most beautiful". Medicinal use, is a dietary health care products, medicines. According to the "Northeast Animal Medicine" records: "Frog fresh or dried line with, can be all into the medicine", "water retention and swelling, detoxification and cough" of the efficacy of the "treatment of edema and cough, measles, excessive menstruation, etc. It can "treat edema and cough, measles, excessive menstruation, etc.". The gallbladder, liver, brain and skin of adult tadpoles can be used for medicinal purposes. Juvenile tadpoles have the effect of prolonging life. It has been found that for the medicinal use of frogs, "Ben Cao Tu Jing", "Ben Cao Gang Mu", "Gleanings from the Compendium of Materia Medica", "Rihuazi Materia Medica", "Animal Materia Medica", "Diffractions of the Materia Medica", "Materia Medica Seeking the Truth", "Materia Medica Summary", "Materia Medica of the Day", "Materia Medica of the Land", "The Great Dictionary of Traditional Chinese Medicines", "Dictionary of Chinese Medicinal Names", "Chinese Medical Dictionary", "Complete Book of Practical Chinese Herbal Medicines", "The Journal of Animal Medicines of China", Chinese Animal Medicine", "Chinese Medicinal Animals", "Medicinal Animals", "Jilin Chinese Herbs", "Compendium of Medicinal Herbs", "Modern Compendium of Materia Medica", "Collection of Modern Research on Traditional Chinese Medicines", etc. It has been recorded in more than 20 Chinese medicine books. Modern research results show that: fresh frog whole per 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 milligrams of calcium, 159 milligrams of phosphorus, 1.3 milligrams of iron, 0.44 milligrams of thiamine, 0.22 milligrams of riboflavin, 2.1 milligrams of niacin.

The frog's body also contains peptides, vitamins, biohormones, enzymes and moisturizing factors. Frogs can benefit mankind because their skins contain compounds to combat disease, including antibacterial and antiviral substances, and there is an 'almost limitless supply' of medicines extracted from frog skins, says Prof. Taillet of Amphibians International Rescue, adding that 'frogs provide a vast supply of new medicines,' and they are 'the pharmacy that hops with the street'."

Medicinal efficacy: frog meat is cool in nature, sweet in taste, with the effect of clearing heat and detoxification, reducing swelling and pain, tonifying the kidneys, nourishing the lungs and nourishing the kidneys.
