How many types of snails are there? What are the varieties of snails?

The varieties of strong snails are: tall ringmouth snail, Hainan snail, wrinkled snail, Jiangxi snail, Ma Shiba snail, white jade snail, Chinese snail, scattered snail, agate snail, Hawaiian snail, etc.

Snails refer to all terrestrial species of the class Gastropoda. In general, Western languages do not distinguish between aquatic snails and terrestrial snails, and in Chinese, snails only refer to terrestrial species, while snails in a broad sense also include giant shield slugs. The snail is an animal that includes many different families and genera.

Feeds on plants and lays eggs in the soil or on trees.

It is more common on tropical islands, but some also live in cold regions. Arboreal species are bright in color, while terrestrial species are usually several close colors, generally striped. The snail is the largest in Africa, measuring more than 20 cm.

Several species of the genus Snail in Europe are often used as delicacies, especially in France. Snails are the most common mollusks on land, and they have high edible and medicinal value.

There are many types of snails, there are 40,000 kinds of snails all over the world, and the common snail species are covered large snails, scattered large snails, bright large snails, brown cloud agate snails, white jade snails, covered large snails, agate snails, Chinese snails, Hawaiian snails, etc. The snail is an invertebrate with saliva on its body, a mouth on the ventral surface of its head, a toothed tongue in its mouth, a prominent head, 2 pairs of antennae, tens of thousands of teeth, and a large number of teeth.

The snail has a carapace, shaped like a small snail, with a variety of colors, and its head has four antennae, and when it walks, its head sticks out, and when it is frightened, its head and tail are retracted into the carapace together, feeding on plants, and laying eggs in the soil or on trees. It prefers to live in a dark and damp, loose and humus environment, is nocturnal, most afraid of direct sunlight, sensitive to environmental reactions, and is widely distributed all over the world.

Snails are invertebrates, molluscs, gastropods, lung snails, snails. The shell is generally low-conical, right- or left-handed. The head is conspicuous, with 2 pairs of antennae, and the apex of the large 1 pair has eyes. The ventral surface of the head has a mouth with a toothed tongue that can be used to scrape food.

Snails have carapaces, are shaped like small snails, and are diverse in color; The head has four antennae, the head is extended when walking, and the head and tail are retracted into the carapace together when frightened; Snails have saliva on their bodies, which can restrain centipedes and scorpions. In June and July, when it is hot, it hangs under the leaves and rises high until it dies after salivaing.

Snails are the animals with the most teeth, but their teeth are not "three-dimensional teeth". Despite having tens of thousands of teeth, they are unable to chew food. This is because they crush food with a toothed tongue – a ribbon-like structure covered with teeth – so that it can be digested.

Over the course of a lifetime, their tiny teeth slowly wear out and dull and are replaced by new, sharper teeth. Snail excretion is excreted close to the breathing hole, which is called a stomata. It will drain its feces on its body, eventually leaving it on the ground through its gastropods and mucus.

There are 40,000 species of snails all over the world, and snails are distributed in all provinces and regions of China, living in dark and damp areas such as forests, shrubs, orchards, vegetable gardens, farmlands, parks, gardens, temples, mountains, flatlands, and hills. It feeds mainly on plant stems, leaves, flowers, fruits and roots. It is one of the agricultural pests and an intermediate host for some parasites of livestock and poultry.

The common species of snails that harm vegetables are: gray snail and homotypic snail, all of which belong to the gastropod class, the order of stalk, and the family of snails, which are terrestrial mollusks with shells. It is mainly harmful to cabbage, rape, radish, bulb lettuce and a variety of special vegetables.

It is a more common harmful mollusk in vegetable fields, distributed throughout the country, and the occurrence of vegetable producing areas with more rain in the south is widespread and serious, and the occurrence in local areas in the north is also more serious. In the past few years, snails were rampant in the leek production areas in the suburbs of Beijing, which seriously affected the yield and quality of leeks and became one of the important obstacles to leek production. This section mainly introduces the pest characteristics, identification, living habits and control methods of snails in vegetable fields.

Snails are terrestrial shellfish mollusks that have lived on Earth since ancient times. Snail.

There are many species, about 25,000 species, all over the world, and there are thousands of species in China alone. Our country has edible value about.

11 species, such as brown cloud agate snail, tall ring mouth snail, Hainan snail, wrinkled scarred snail, Jiangxi Ba snail, Ma's.

Ba snails, white jade snails, etc.

At present, there are three main types of snails that are eaten and artificially bred around the world: French snails, Chinese snails and garden snails.

The types of snails are: French snails, Chinese snails, garden snails, agate snails, carnivorous snails, etc.

1. French snails

The French snail is also known as the grape snail because it lives in grape plantations and feeds on grape stems, leaves, buds, fruits, etc. And because its shape is very similar to an apple, it is also known as an apple snail, and its scientific name is the covered snail.

2. Hua snail

The snail is generally low conical, 16 mm wide and 10 mm high, and the chitin is not only thin but also solid, and the shell is medium to large. The top of the shell is slightly disc-shaped, the suture line is more pronounced, the spiral part is relatively low, and there is a spiral layer. The shell surface is yellow or yellowish-brown, the body snail layer is extremely expanded, and there is a light brown color band around its periphery.

In addition, the mouth of the shell is oval, with a white porcelain-like rib and a lighter ribbon of color near the suture line at the lower part of each spiral layer.

3. Garden snails

Garden snails belong to the "halix" snail, which is native to France, England and other regions in central and western Europe, and generally inhabits gardens or shrubs, so it is called "garden snail", also known as the scattered snail.

The chitina of the adult snail is relatively thin, yellow-brown, relatively small, about 3cm in diameter, and has 4 purple-brown bands, and the surface of the shell is covered with many small yellow-brown spots. Since the beginning of time, the scattered snails bred in China have poor economic benefits due to small individuals and degraded varieties.

4. Agate snails

Taiwanese call it a snail, and in Guangdong, it is called a flower snail, a vegetable snail or a Dongfeng snail, which belongs to the agate snail class. Native to the West island of Malaga in East Africa, the agate snail was later distributed throughout the tropics and is the largest snail in the world, also known as the African giant snail.

5. Carnivorous snails

This carnivorous snail feeds mainly on its close relatives and lives in Mount Kapata near Narabury, New South Wales (about 520 kilometres southwest of Sydney). Believed to be endemic to the Kapata Hills of New South Wales, the carnivorous snail feeds only on terrestrial snails of the local vegetarian diet and is thought to have originated in eastern Australia, which was once covered with humid rainforests.

Snail is not a biological taxonomic name, but generally refers to all terrestrial species of the class Gastropoda.

In general, Western languages do not distinguish between aquatic snails and terrestrial snails, and in Chinese, snails only refer to terrestrial species, although they also include many animals of different families and genera, but they are all similar in shape.

Snails belong to mollusks, gastropods; Feeds on decaying plant matter and lays eggs in the soil.

It is most common in tropical islands, but it is also seen in cold regions.

Arboreal species are bright in color, while terrestrial species are usually monochromatic.

The agate snail in Africa is the largest, mostly more than 20 cm.

Several species of the genus Snail in Europe are often used as delicacies, especially in France.

Snails are one of the most common mollusks on land, and snails have high edible and medicinal value.
