What are the marks left by a snail after it has walked by?

White glowing saliva line.

Why does the place where the snail crawls leave a trail of slime? Snails are mollusks.

A member of the family crawls on the ground every day with his own small house on his back. Everywhere it crawled, it left a trail of slime, and when it dried, it formed a shiny line. Why does the place where the snail crawls leave a trail of slime?

Snails have a peculiar appearance, they have no bones and almost all of their bodies are muscles. The snail carries its "little house" on its back all day long, with its spiral-shaped shell, sticking out its soft body and slowly squirming forward with its flat, sucker-like feet, which have a gland called a foot gland, which secretes a type of mucus. This mucus helps snails crawl and increases their crawling speed.

In this way, where the snail crawls, it leaves behind mucus secreted by the foot glands. Slugs.

The saliva marks left after climbing on the paper or cloth will make the texture of the paper or cloth more brittle; The saliva marks left by the snail after crawling on the paper or cloth do not make the texture of the paper or cloth brittle.

The ventral surface of a snail has flat, wide gastropods with many glands that secrete mucus. This mucus reduces friction, helps snails crawl, increases their crawling speed, and prevents ants and other insects from harming snails while dormant. This mucus is left behind wherever the snail crawls.

Snails are gastropod mollusks that live on land. When crawling, it uses its feet to cling to other objects, and its foot muscles wriggle in waves, and crawl forward slowly. A snail's foot has a gland called a foot gland.

The foot glands produce a very mucus trace. When this mucus trail dries, it forms a sparkling saliva line.

During hibernation or summer hibernation, the mucus secreted by the foot glands forms a membrane at the mouth of the shell after drying up, which tightly seals the body and breaks through the membrane when the external environment is suitable. Snail specimens stored in the herbarium are protected by a thin film and can not die for several years.

Mucus is secreted from the snail's gastropod[Source]Snail snails live on land. Snails need a humid environment. When it doesn't rain, the snails hide in the shadow of stones or in the crevices of tree stumps all day long, and only come out at night.

Early in the morning, the traces of slime left on the leaves tell us that the snails have been here. After the rain, we can often find snails in the corners, under trees, in grass, and on vegetable leaves. The main food of snails is the stems and leaves of plants.

If it's spring, it's possible to see several snails sticking to each other, and spring is the breeding season for snails. In winter, the snail seals the opening of the shell tightly with a thin film formed by mucus and hides inside for the winter. The body of the snail is soft and has a spiral-shaped shell on the outside, right- or left-handed, with a mantle attached to the shell.

The warm head has two pairs of antennae, the front pair is shorter; The back one is longer in contrast, and there is an eye at the top. The ventral surface of the warm body is flattened and muscular, forming the gastropod, which is the locomotor organ of the snail. There are foot glands in the gastropod that secrete mucus, keeping the gastropod moist and avoiding injury while crawling.

After the snail crawls over the walls, leaves, etc., it always leaves a clear trace, which is formed by the mucus secreted by the foot glands. The mouth of the snail is on the ventral surface of the head, and the mouth has jaws and toothed tongues. The jaw piece has the effect of chewing food.

The tongue of the teeth has many small teeth that are arranged in a neat manner, and the tip of the tongue can protrude from the mouth to scrape food. Snails belong to the class Gastropoda, the subclass Lung Snails, and the family Snails among mollusks. Molluscas are characterized by a soft body, a shell on the outside of the body (or has been degenerated), and all have a mantle.

Since mollusks generally have shells, mollusks are also commonly referred to as shellfish. The mollusks we are more familiar with include snails, slugs, mussels, oysters, clams, clams, cockles, squid, octopus, squid, etc.

It is mucus secreted by snails, which is white when dried.

The snail moves in a wavy shape, and the abdomen gives birth to a movable fleshy foot called gastropod, which is equivalent to the snail's foot. When the snail moves, mucus can be secreted under the gastropod, which reduces friction and helps it crawl. This slime dries quickly and shines as soon as it hits the air.

It is a mark left by a kind of mucus produced by the snail itself, which allows it to attach to the crawling surface and avoid falling off, or it may be a mark left by him, for himself and his companions! If it dries in time, it will leave a special smell!
