What are the characteristics of snail's appearance and movement?

The shell is generally low conical, right-handed or left-handed. The head is prominent, with two pairs of antennae, the larger pair of which has eyes on the top. There is a mouth on the ventral side of the head, with a radula inside the mouth, which can be used to scrape food.

Snails have shells that are shaped like small snails and have various colors. They have four tentacles on their heads. When they walk, their heads extend out. When they are frightened, they retract their heads and tails into their shells. Snails have saliva on their bodies that can restrain centipedes and scorpions. In the heat of June and July, they will hang under leaves and rise upward until they finish spitting and die.

The snail's mantle cavity forms an opening at the shell opening, called the "breathing hole", which is where gas enters and exits. If you observe carefully, you will see that the breathing hole often opens and closes, just like the snail's "nose" for breathing; and when the snail retracts into the shell, it will still leave the opening of the breathing hole at the shell opening for breathing. The mantle often forms a cavity between the feet or internal organs that communicates with the outside world, called the "mantle cavity". The snail's respiratory organs are hidden in the mantle cavity.

When a snail crawls, it leaves a line of mucus on the ground. This is a liquid secreted from its body, so it will not be in danger even if it walks on a knife edge.

Why do snails hibernate?

Snails hibernate not to avoid the cold. Snails can withstand temperatures as low as dozens of degrees below zero. They hibernate because they lack food. When they hibernate, they first hide in the corner of the wall, then secrete some mucus from their foot glands to seal the shell opening with a windproof film, and then sleep peacefully for the winter. Snail is not the name of a biological classification, but generally refers to all terrestrial species of the gastropod class. Generally, Western languages ​​do not distinguish between aquatic snails and terrestrial snails. In Chinese, snails only refer to terrestrial species, while the broad definition of snails also includes giant shield slugs. Snails are an animal that includes many different families and genera. They feed on plants and lay eggs in the soil or on trees. They are more common on tropical islands, but some also live in cold areas. Arboreal species are brightly colored, while terrestrial species are usually of several similar colors, usually with stripes.

How do snails spit out dirt quickly?

First, you should fast and rest, select snails of moderate size, healthy and active, weighing more than 35 grams, put them into a basket and cover them with the top cover, and place them in a cool and humid place to fast and rest. During this period, you should wash them with clean water to wash away the dirt outside the shell and encourage the snail to excrete waste in the body.

Then rinse the snails with clean water and place them in a clean pool or other containers such as basins and pots. Sprinkle salt evenly on the snails at a ratio of 1:100 to the weight of the snails. Stir slowly and shake the snails in a basket. At this time, the snails will retract their heads and feet into their shells when they are stimulated by the salt. Then sift the salt through a sieve, and the snails will spit out the dirt.
