What do geckos do climbing walls? How do geckos climb walls?

Geckos climb the wall to catch bugs to eat. Geckos are generally eaten by insects and flying insects, which are generally the food of geckos. These bugs tend to be on the walls.

In order to find and catch these bugs, geckos can only look around the walls for these bugs. Here's a brief introduction to why geckos can be attached to the wall without falling off.

Enumeration: 1: Geckos have a special body structure with a deep furrow growing on each toe.

These deep grooves not only increase friction between the toe and the smooth surface, but also attach the body to the smooth surface. It is for these reasons that geckos do not fall off the wall no matter how they move. These special body structures are particularly suitable for the living habits of geckos.

2: Geckos have the ability to crawl. Geckos have tens of thousands of fine hairs on their toes, each 100 microns long, and these tiny hairs are topped with thousands of smaller branches.

The stickiness of the gecko's toes is achieved by the intermolecular forces formed by the bifurcations on these tiny villi and the molecules on the surface of the object. These phenomena were originally thought to secrete a glue substance from the toes of geckos, but later scientists discovered them under a laboratory microscope. Geckos are generally a more amazing creature.

3: Types of gecko food. Geckos still have a wide range of food types, but geckos mainly eat live insects smaller than themselves, such as flies, crickets, mosquitoes and cockroaches.

If you are a domestic gecko, you can feed insects such as mealworms, bread bugs, spiders, ants, praying mantises, and moths.

When the gecko crawls on the wall, its toes (toes) are thick, and the ** under the fingers (toes) forms a lot of horizontal folds, which can play the role of a sucker, so the gecko can crawl on the upright wall and can't fall off, crawl on the wall to catch insects to eat.

Geckos climb walls to catch insects to eat.

Geckos climb walls to hunt and escape predators.

Originally, it was thought that geckos secrete a gelatinous fluid from their toes, allowing them to stick to the ceiling. Later, it was proposed that the gecko relied on the suction cups on the toe enlarged joints to create a vacuum of suction, so that it could stick to the ceiling. It is even believed that static electricity can be generated on the toes of a gecko, allowing it to attach itself to the ceiling.

So what is the reason why geckos can freely "fly on the wall"?

When the electron microscope was introduced, biologists used high-tech instruments to uncover the secrets on the geckos' toes. Originally, the toes of the gecko were padded at the front of the toe and were made up of many plates, arranged in a fan-like pattern, or arranged in parallel. These plates are scales covered with microvilli.

The villi are made up of keratin, like small hooks. Geckos have millions of tiny hooks on their feet, so that they can easily grasp the tiny protrusions on the surface of objects, even smooth glass surfaces are rough compared to these tiny hooks, and ceilings and walls can be said to be "bumpy". That's why geckos can walk lightly on ceilings and walk on the ground.

In order to understand the specific movements of geckos climbing walls, scientists have made further observations, but most geckos are small and move very quickly, and it is difficult to see the details of the movements of the soles of their feet. In Malaysia, there is a large gecko that moves slowly, and it was found that its claws and foot pads were strong and powerful. When they climb the wall, they settle on the wall, and the foot pads are pressed back and down so that the fluff can hook the wall, and when they lift their feet, the foot ends will be rolled up backwards and upwards to dehook the fluff from the wall, so that the feet can be lowered and rolled up alternately, so that the gecko can move quickly on the wall.

If one day a device can be developed that mimics the foot end of a gecko, then firefighters can climb up and down high-rise buildings with ease.

In addition to this extraordinary ability to climb walls, the gecko's escape ability is also a must. When infested by normal enemies, it will move quickly and flee into cracks in walls. When it is too late to react to escape, it will cut off its own tail, and the broken tail can jump violently on the ground, attracting the attention of the enemy, and the gecko can take the opportunity to escape.

The tiny hairs on the geckos' toes have a dispersion force between them and the molecules on the surface of the wall, and they will stick to them tightly, like adhesive tape. Similarly, lifting the foot is to lift the toes around the toes first, and then lift the middle part as if tearing off the tape that sticks to the wall, which is the fastest and most labor-saving, so that the gecko can move quickly.

Geckos have feet suitable for climbing; The toes are long and flat, and the flesh on the toes is covered with small plates; The disc is sequentially covered with tiny hairy protrusions, and the ends are forked. These hooks, which are invisible to the naked eye, adhere to irregular facets, allowing geckos to climb extremely smooth and vertical surfaces, so geckos can climb walls.

Geckos can climb on the wall, because the gecko's toes grow hundreds of thousands of bristles, the size of the bristles can be compared with the molecular size, the gecko climbing wall bristles can be inserted between the wall molecules, and produce intermolecular force, and this is also the main factor that the gecko can climb. It has been calculated that one bristle can bear the weight of an ant, and 1 million bristles can carry 20 kilograms of force, although the area arranged together is less than the size of a coin.

The fingers of the gecko's limbs are flat and broad, with **folds forming underneath, with countless microscopic glandular hairs, and with adhesive ability, it can crawl on walls, ceilings, and smooth surfaces. In addition, the hook and claw play an extremely important role when the gecko crawls on the wall, and the white fold plays an extremely important role when crawling on the glass.

Therefore, the following conclusions can be drawn: geckos crawl on the wall, hook the protruding particles on the wall with their hooks, crawl forward with the alternating movement of the front and rear feet, and the folds on the white folds will be inserted into the hollows of the wall one by one to play a stabilizing role, and at the same time, the tail swings from side to side and the body coordinates to maintain balance.

When the gecko is frightened or caught, as long as it touches the gecko, the gecko's tail will immediately break, and the gecko will take the opportunity to escape. This phenomenon is called "self-cutting" in zoology, also known as "self-cutting", "self-mutilation" and "self-cutting".
