How can you tell the snail to climb faster, why does the snail climb up

Animals like snails have always given the impression that they struggle to move, but bionic scientists have found that the way snails crawl also contains the wisdom of nature. Its main magic weapon is the mucus it secretes. The snail can not fall off the wall, relying mainly on the stickiness of its mucus; But the snail is not stuck to the wall like glue, and it uses the slime as a lubricant when it crawls.

If the snail's slime is thick enough to bear its own weight, doesn't it have to crawl on this slime all the time with its own weight level? This is a strenuous task for most terrestrial creatures. In fact, the mucus secreted by the snail is not such a simple liquid, and its properties can make the snail "four or two thousand pounds" on the wall.

The viscosity of a classic liquid is a constant and does not change with external forces. But the mucus of the snail is different, when the external force applied is small, its viscosity is very large, and it appears as a very sticky thing, which can stick the snail without slipping down. However, when the applied external force is greater than a certain value, its viscosity will suddenly drop and become a very thin thing, which has a lubricating effect and allows the snail to crawl easily.

If the external force is removed, the viscosity of the mucus can quickly return to its original level, so that the snail can stop without sliding too far backwards. Therefore, when the snail crawls, it does not have to exert its weight all the time, as long as it exerts a little effort when it is just "started", the slime becomes very thin, and it is easy to crawl. This property of the snail's mucus is called "yielding".

If the strength is not great, it is strong; When the strength is great, it "succumbs" and becomes a very weak thing. If you want a snail to climb faster, you need to find a liquid that becomes thinner after yielding, and recovers quickly when it is still. In the real world, it's hard to find an extremely contradictory liquid.

Studies have found that the mucus secreted by snails has reached its optimal properties. Many of the yield fluids in man-made products, if used for snails, not to mention that they can climb more slowly, or even climb at all. For example, the ketchup packaged in a glass bottle cannot be poured out after a long time, and it needs to be shaken vigorously for a long time.

But once it is shaken out, it is easy to "snap" and pour out a large puddle, which is nothing more than succumbing. However, the ketchup will take a day to return to its original viscosity, and if it is used by a snail, it will either crawl non-stop, or it will not stick when it stops.

It's so simple, just put the snail in the water, and the snail likes water, but whoever has more of it can't stand it.

Climbing up <> snail is an instinct that has gradually formed in the long-term evolution of snails in order to adapt to survival. Snails eat a variety of vegetables, weeds and melon peels, and these foods, especially the fresh leaves of plants, are generally found at the upper end of the plant, and the snails that tend to climb down are eliminated by nature because they do not get enough food.

The snail's climb to the tree is an instinct that has gradually formed in the course of long-term evolution in order to adapt to survival. Snails staple eat a variety of vegetables, weeds, melon peels, etc., while the tender plant leaves usually grow on the top of the plant. In addition, although snails like humid environments, they are prone to water accumulation in low-lying areas after rain, so they climb up to prevent drowning.

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 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.

01 There is a wide and thin horizontal fold on the snail's abdomen, and the back end is pointed, which is its "foot". When a snail crawls, it can crawl forward slowly by clinging its feet to other objects and wriggling in waves through its abdominal muscles. At the same time, there is a gland on its foot, called a foot gland, which secretes a mucus that helps it crawl.

There are many kinds of snails, but they have a lot of use value, and there are many skin care products in the skin care industry to extract snail essence to make some high-end skin care products, and they are also very popular. How do snails crawl?

The flat feet under the snail's belly are actually stripes, and these horizontal stripes ripple backwards like water ripples, and the snail relies on the fluctuations of the horizontal stripes, and there is a small thing called "foot gland" in the snail's foot, and the sticky glue-like thing is secreted by the foot gland. When crawling, this mucus constantly flows out to reduce friction and facilitate the crawling of snails.

And secrete mucus along the way to make it easier to move around rough ground. If attacked, they secrete another yellowish slime to deal with enemies.

But only the mucus secreted when attacked is poisonous. During hibernation or summer hibernation, the mucus secreted by it can also form a thin film at the mouth of its shell, sealing the body and then breaking through the membrane when the external environment is suitable.

Even a standard snail can survive for years with a mucus-sealed shell.

1. The flat foot under the snail's belly is actually a horizontal stripe without rock, and these horizontal stripes fluctuate towards the preparation after the annihilation like water ripples, and the snail crawls slowly by the fluctuations of the horizontal stripes;

2. There will be a shiny line where the little snail crawls over, which is a small thing called the foot gland in the snail's foot, and the sticky glue-like thing is secreted by the foot gland;

3. There will be mucus flowing out when crawling, in order to reduce friction.
