First of all, let's tell you the answer: snails don't shed their shells! The life of a snail is shorter, the longest is only 6 years, in these six years, if you live in a cold area, you have to sleep for almost half of the year, excluding hibernation events, the time you are awake is only a maximum of 3 years, in these three years, it has too many things to do, and it is so ink.
Slugs. A "snail" without a shell, the name may sound tongue-twisting, but its colloquial name you must know: "slug."
It is the same as a snail, male and female, monoecious, the only difference is that one has a property, and the other is a northern drifter.
Snail shells are all grown in a spiral pattern, with the spiral increasing layer by layer. You will find that due to hibernation and other reasons, sparse longitudinal "growth lines" will form on the shell, similar to the growth rings of large trees. The snail shell grows with the snail until it is fully mature, at which point the shell stops growing, like a human bone.
The shell plays a vital role in the snail, this is compared with slugs, folk legend, slugs will turn into water when they encounter salt, although this statement is not very accurate, but the difference between a house and a house is still huge. So, every slug has a next life.
When the heart of a snail.
When it comes to shells here, I might as well tell you a very interesting point, the vast majority of animals with shells in the world are dextralhelmsVery few are left-handed, and if you do, you're really lucky!
In fact, this is all exoskeletons.
Common problems of animals ......The snail still has an opening, and the exoskeleton of insects and other animals that enclose the body is completely gone, and the only way is to molt regularly.
In contrast, endoskeletons like humans are much less troublesomebecause of our periosteum.
and so on, which are attached to the outside of the bone. If you're standing on the outside of a house, you can make it as big as you want.
-
The snail will change its shell, so the snail's shell will not get bigger.
-
The shell of a snail grows as its body grows, unlike hermit crabs that always "move".
-
Yes, the shell of a snail is also part of the snail's body.
-
Yes, the body of a snail is attached to its shell.
-
Of course it will, just like the ** of human beings will transform.
-
Yes, because the shell and the snail are interdependent.
-
Of course it will, after all, it is a body of one.
-
Yes, because they are one in their own right.
-
The shell of the snail itself is part of the snail's body.
-
The shell of a snail is not made of cells, unlike the shell of a turtle, but more similar to the shell of a hermit crab.
-
Most snails grow in a spiral pattern. During the growth phase of the snail, the shell spirals up layer by layer. However, due to the fact that the growth process of snails will go through many periods, such as the breeding period, dormancy period, etc., as well as various factors such as climate change and food abundance, resulting in different growth rates of the shell, so the longitudinal growth lines of sparse phases will be formed on the surface of the shellUntil the snail grows to adulthood, the snail layer of the shell does not progress.
The number of snail layers of each species of snail is a fixed characteristic, some species have more snail layers, some species have fewer snail layers, but if there are natural and man-made disasters such as environmental discomfort, the number of snail layers will be slightly different (may add or subtract 1 2 layers or 1 layer).Since the shell of a snail is a structure that grows with snails from birth, snails do not need to change their larger shells every once in a while, like hermit crabs, to accommodate their growing bodies. Therefore, if the snail is forcibly removed from the shell, the snail will only die.
-
The whole body of the snail includes eyes, mouth, feet, shell, antennae and other parts, and the spiral shell on the back of the body, its shape, color and size are different, and their shells are pagoda-shaped, top-shaped, conical, spherical, pipe-shaped, and so on. At present, the white jade snail, the cover snail, the scattered snail, the bright snail, the brown cloud agate snail, etc., all have their own unique appearance. The eyes of the snail grow on the back pair of antennae on the head.
-
The snail has a mantle inside its shell that secretes the constituent substance of the shell, which is used to make the shell. However, whether the damaged shell can be repaired depends mainly on the specific situation of the damage. Specifically, it is basically divided into the following three situations:
1. Slight damage.
If only a small part of the shell is damaged, and the mantle does not injure the mantle, the mantle can secrete a shell constituent substance to repair the damaged part, and the damaged part will be slightly lighter in color than the "original" part after repair.
The regrowth of the cracked shell gradually changed from white and transparent at first, to yellow, and finally to a color and texture similar to that of the original shell. However, there will still be scars, and you can see that it is repaired.
2. Moderate damage.
If the damage and mantle are broken, the damaged area will not repair itself, but will only grow into scarred connective tissue, and the snail may continue to survive.
3. Severe damage.
If the damage and internal tissues are broken, the external microorganisms are directly invaded into the snail's body, due to the slow metabolism of the snail, it is difficult to repair the wound in a short time, and the continuous invasion of microorganisms will have a serious impact on the snail, so the possibility of snail survival is relatively small.

<> snails do not shed their shells unless humanized acts. There is a mollusk without a shell called a slug, not a snail, both are gastropods, but the slugs belong to the slugs family, while the snails belong to the great snail family.
The role of a snail's eyes is simply to perceive ambient light. The head of a snail has two pairs of antennae, one of which has eyes at the tip of a large antennae. >>>More
Those white marks are actually mucus on the snail's body, the mucus is secreted from the snail's gastropod, the snail lives on land, and he needs 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. >>>More
Snail is not a biological taxonomic name, but generally refers to all terrestrial species of the class Gastropoda. >>>More
The color of the shell is similar to the color of the earth. However, there are other colors as well.
Generally, 1,000 hand-free snails can be raised to earn about 10,000 yuan a year. The prospect of breeding snails is considerable, because the medicinal value of snails is relatively high, and the sales channels of snails are also very wide, involving medicine, food, beauty, feed and other simple ears, and there are large sales markets at home and abroad. Generally, as long as the mature breeding technology is mastered and there is a stable market, the risk of breeding snails is relatively small.
