Geckos crawl around the wall every day, why don t they fall?

When you think of martial arts masters, do you think of masters in various film and television works? As masters, flying cornices and walking walls is an indispensable basic skill for them. Martial arts practitioners train hard to make their bodies lighter and more vigorous, and then they can land on the eaves of the wall, geckos.

But no. Flying eaves and walking on walls is their innate ability, and their martial arts masters have started since childhood.

A gecko that flies over the eaves will not break, why can a gecko step flat on the wall.

Why do geckos swim up walls so easily? This question arose as early as the 4th century BC in Aristotle.

but he failed to give a good explanation, and then the problem troubled scientists for many years. Some people think that the feet of geckos are suction cups, so they are easy to attach to the wall. Some say that geckos can stick themselves to walls by secreting a sticky substance.

Some people think that it resembles a spider with spines on its feet and can climb at will.

What they say seems to make sense, but with the development of research and electron microscopy.

, these claims were gradually overturned. Under the microscope, the paws of the geckos' feet are clearly visible. You can find that it has no octopuses or leeches on the soles.

Such a powerful suction cup, there is no sticky substance secreted by insects climbing walls. Of course there are no barbs, and it's strange to have barbs.

So, how does it fly over the eaves? Of course, there is a way of master. It may frighten everyone to say it, but the application of geckos actually comes from the most basic physical principle in the universe - molecular gravity.

Even when applying the principles of physics, the master design is extraordinary. Molecular force of attraction, also known as van der Waals force.

It is a weak basic electrical force of attraction that exists between adjacent neutral molecules or atoms. This gravitational pull is universal and weak, and it existed before the human body and the wall, but the person can't easily absorb the wall, so no one cares. But this gravitational pull shines brightly on the gecko.

Looking at the microscope, we can see that the gecko has bristles on its feet, and the number of bristles is not as large as usual. There are millions of bristles on each foot, with 400-1000 finer branches at the ends of the bristles. Some look like human hair has been split, but the number is far from being split.

In the case of this tight bristles, each bristle creates a molecular attraction to the wall. Scientists say that according to scientific calculations, one mane can lift an ant, so the millions of manes on a gecko's feet can easily support its body on any surface.

Climbing the eaves is just a skill for the gecko to become the owner, and the speed of the gecko's movement is also an unapproachable factor for the gecko to become the owner.

The main thing is that the soles of the gecko's feet have a strong ability to absorb, so even if it crawls around the wall, there is no danger of falling.

Because the gecko's claws have a grip, it won't fall off.

Because the gecko's feet can be firmly grasped on the wall, they will not fall.

This is because the gecko has suction cups on its claws, and the soles of his feet are very strong and can move freely on walls.

Because this animal has some kind of organ that allows it to lie on the wall and not fall off.

Generally speaking, geckos will not move for a few days for many reasons, such as they may be looking for food, they may be thinking about how to get where they want to go, and sometimes it may be because they are afraid to move easily. In addition, geckos may also be immobile for several days due to the hot weather, and they will quickly destroy themselves in a shady position to hide themselves from the storm and slow down their metabolism, so as to maintain the body's energy consumption per acre and the stability of body temperature.

The geckos are able to climb walls without falling off because their flippers have a structure called "suckers". The surface of these flippers is covered with many tiny hairs, each of which branches into tiny curved hooks in the same direction, which can attach the gecko to the vertical surface, creating enough friction and adhesion. Geckos use their muscles to contract and expand rapidly as they climb, allowing their flippers to "suck" and move with them, while releasing muscles to relax their flippers so they can reattach to their new positions.

The geckos stay on the wall for a few days, probably because they are waiting for their prey to appear. Geckos are carnivorous reptiles that are good at catching small arthropods such as insects, spiders, and ants. They usually hide in leaves or crevices in walls, waiting for their prey to approach before pounce and catch them.

Therefore, when geckos stay in the same position for a long time, it is most likely because they are waiting for the arrival of their prey, waiting for the best time to attack.

1 It may be that the gecko is waiting for its prey or resting, so it does not move.

2 Geckos have a strong adhesion and can crawl on vertical walls, and their claws have many small hairy structures that can increase the surface area and improve adhesion, so the slag will not fall even if it stays on the wall for a few days.

3 In addition, geckos' bodies are also very adapted to crawling vertically, and their brains and inner ears help them control their balance and position, so they will not feel uncomfortable staying on a noisy wall for a few days.
