Is the amphibian toad (toad) a pest? What's the difference between frogs and frogs? Can toad poison people?

Toad, also known as toad. Belong to amphibians, and frogs are also amphibians, in normal times, because there is little difference in appearance, so many friends are not very clear about the distinction between the two kinds of animals, is the toad a pest? What's the difference between frogs and frogs? Can its toxicity kill people?

Toad, commonly known as toad, belongs to the amphibian of toad family. It is not only an agricultural guard for preying on pests, but also a combination of medicine, health care and delicious food, so it is known as "toad treasure" and is a medicinal animal with high economic value. So it's not a pest.

What's the difference between a toad and a frog?

I. the difference of families and genera between frogs and toads

1. Frogs: frogs belong to the amphibians of the animal kingdom, phylum Chordata, subphylum Vertebrata, amphibia, Anura, New Frog suborder, Frog family and Frog.

2. Toads: toads are animals of the kingdom Animalia, phylum Chordata, subphylum Vertebrata, amphibia, amphibia, Anura, Bufonidae, and Bufo.

2. The difference between the tadpoles of frogs and toads

1. Frogs: most of the tadpoles of frogs are scattered, with a lighter body color, a slightly round body, a long tail and a long mouth at the front of the head.

2. Toads: the tadpoles of toads are usually crowded in groups, with a black body, a shallow tail, an oval shape, a short tail, a mouth on the ventral front of the head, and a body smaller than a frog tadpole.

III. Morphological differences between frogs and toads

1. Compare skin and body color

Frogs have two longitudinal folds from the back of their eyes to the base of their hind legs, which are golden yellow or light brown. There is a light vertical pattern in the center. There are a lot of black markings on the hind legs. The frog's back is brown or yellowish green and its ventral side is white. The toad has rough skin and verrucous protrusions of different sizes all over the body. Dark brown on the back and milky yellow on the ventral side.

2. it is observed that toad has abundant toxic glands, which are divided into skin gland and retroauricular gland. Skin glands are distributed on the back of the body, where the epidermis thickens into "warts". The retroauricular gland is above the tympanic membrane of the head. Be careful to pierce the retroauricular gland with a needle, and the milky and toxic serous will flow out. Frogs have no poisonous glands.

3. Observe that there is a pair of vocal sac behind the mouth corner of the male frog. When making the sound, the gas in the mouth is pressed into the vocal sac, making it enlarge into a ball, while the female frog has no vocal sac. Toads have no vocal sac either male or female.

4. Comparing teeth and tongue frogs, there is a row of small maxillary teeth at the upper edge of the maxilla, and there are also two rows of verrucous protuberances on the top of the oral cavity, called ploughbone teeth. The toad has no teeth in its upper and lower jaw. Pull out the frog's tongue, the tip of its tongue is bifurcated, while the toad's tongue is unforked.

5. Two ureters of frogs connected with ureter and cloaca were respectively connected with cloaca, and there were two openings on the wall of cloaca, while toad's two ureters were first merged into a total ureter, and then entered the cloaca and there was only one opening on the cloacal wall.

6. Observe the connection between the fallopian tube and the cloaca. The two fallopian tubes of the frog are also connected to the cloaca, while the toad merges first and then communicates with the cloaca.

7. Comparing the two upper black beak bones of shoulder straps frogs are closely parallel but do not overlap and cannot be staggered, which is called chest-fixing shoulder straps, while the upper black beak bones on both sides of toads overlap each other and can be staggered, which is called arc-chest shoulder straps. In front of the inner end of the frog's clavicle, there is a rod-shaped shoulder sternum and half round cartilage in front of the shoulder sternum, which is the upper sternum. And toads don't have these two bones.

8. Comparing the first seven vertebrae of the vertebral frog, the front part is concave and the back end protrudes, which is called the anterior concave type, while the eighth vertebral body is double concave, while the toad's first 8 vertebrae are all anterior concave type.

Toad epidermis is keratinized, so it is more drought-resistant and can move in a dry environment far away from water. Although the body colors of frogs and toads are different, they all play a protective role in different living environments, and vary greatly under the influence of the environment. Toads are far less capable of jumping than frogs, but venomous glands protect them from predators, which are protective organs. The male frog has a pair of vocal sacs and is a vocal resonator. Frog maxillary teeth are the same type of teeth, these teeth have no masticatory function, only to prevent small animals from slipping out of the mouth. The location of teeth, the bifurcation of the tip of the tongue, the type of shoulder straps and vertebrae are all the basis for the classification of tailless amphibians. The difference in the connection between the ureter and fallopian tube and the cloaca of frogs and toads is often a difference that is easy to be ignored in anatomy.

IV. The difference in efficacy between frogs and toads

1. Frog: frog taste sweet, cool, return to lung, spleen and bladder meridian, with the effect of diuresis and detumescence, clearing heat and detoxification, tonifying deficiency, mainly treating edema, swelling, jaundice, shrimp plague, infantile fever, dysentery, dysentery, labor fever, postpartum weakness and so on.

2. Toad: toad taste fishy, warm, poisonous, return to the heart meridian, with detoxification, pain, Kaiqiao and other effects, mainly for the treatment of eczema, back, gangrene, acne, dysphagia, distension, edema, infantile accumulation, chronic tracheitis and other diseases.

Fifth, the difference between tadpoles

1. Observe whether the tadpoles swimming in the water are dense or scattered. The former are often the tadpoles of toads, while the latter are mostly tadpoles of frogs.

2. Pick up the tadpoles with a fishing net and observe them in a glass bottle or on the palm of your hand. The tadpoles with lighter color, slightly round body, long tail and mouth at the front of the head are frog tadpoles. The tadpoles with black body, shallow tail, oval shape, short tail and mouth on the ventral front of the head are toad tadpoles.

3. When the front end of the tadpole's head is observed with a magnifying glass, the arrangement of their horny fine teeth is also different. There are three rows of horny fine teeth under their lower lip, but the upper row teeth of frogs are interrupted, while the three rows of fine teeth of toads are constantly opened.

4. Most of the tadpoles seen before and after the Qingming Festival are toad tadpoles, while frog tadpoles can not be seen until the middle of May.

Toads can't eat at random! Nine out of ten are poisoned.

In the folk, scorpions, snakes, toads, geckos and centipedes are called five poisons, so how big is the toad toxin?

Toads, commonly known as toads, look like frogs, and their skin is rougher than frogs. It is a poisonous animal, its parotid glands, blood vessels and skin glands secrete white serous and toad eggs contain more than 30 kinds of toxic substances.

If processed or handled improperly, toxins may enter toad meat, resulting in dizziness, headache, vomiting, diarrhea and other symptoms, serious damage to the heart, liver, kidney and other organs, and even death. As a matter of fact, it is not uncommon for toads to die from eating toads every year, some of which are eaten by mistake, and some believe that folk folk prescriptions are specially caught to eat.

Not only can not eat indiscriminately, catching toads is also illegal!

As the toad after special processing and extraction has a certain medicinal value, so it also gave birth to many people wantonly catch toad, but this is also illegal.

According to the forest public security, toads are animals protected by the state's "three have". According to China's criminal law and relevant laws, it is illegal to catch one (article) of the "three animals" without approval, and it is a crime to catch more than 20 (articles). The capture of more than 50 (articles) is serious, and the capture of more than 100 (articles) is particularly serious.
