The four-legged snake is the colloquial name for the lizard, the most thriving group of living reptiles, distributed throughout most parts of the world. There are about 3,000 species of lizards in existence, and the largest of the modern lizards is the Indonesian Komodo dragon (also known as the Komodo dragon), which can grow to more than 3 meters. The gecko is a group of lizards, which is the whole of the gecko family, the gecko genus, the webless gecko or several other types of geckos.
There are more than 20 species of geckos known worldwide; There are currently 11 species known in China.
Lizards are ectotherms. Lizards living in temperate and cold zones go dormant in winter, showing seasonal changes in activity. Lizards that live in the tropics can be active all year round due to their warm climate.
But in particularly hot and dry places, there is also the phenomenon of summer hibernation to survive the harsh environment of high temperatures, dryness and lack of food. It can be divided into three types: daytime activity, nocturnal activity, and morning and dusk activity. The formation of different types of activities mainly depends on the activity habits of food objects and other factors.
Most lizards eat animal food, mainly a variety of insects. Geckos are nocturnal and feed on insects such as Lepidoptera. Larger lizards such as large geckos can also feed on small birds and other lizards.
Monitor lizards can eat fish, frogs and even small mammals. There are also some lizards such as iguanas, which mainly eat plant-based food. Since most species hunt large numbers of insects, the role that lizards play in controlling pests cannot be underestimated.
Many people think that lizards are poisonous animals, which is not true. There are only two known species of venomous lizards in the world, which belong to the family of venomous lizards, and both are found in North and Central America.
Many lizards often cut off their tails when they encounter predators or are severely disturbed, and the broken tail keeps beating to attract the attention of the predators, but it itself escapes. This phenomenon is called self-interception and can be thought of as a protective adaptation to escape from the enemy. The lizards of the gecko family, the snake lizard family, the lizard family and the skink family in China all have the ability to self-intercept and regenerate.
Geckos mostly inhabit the cracks in the walls of houses and in the cracks of stones. It is distributed in Liaoning, Hebei, Shandong, Henan, Shanxi, Shaanxi, Anhui, Jiangsu and other provinces. Others are multi-wart geckos, which are found in central China; Wart geckos, distributed in southeastern China; Webbed-toed geckos, distributed in Guangdong and Guangxi.

Difference Between Four-legged Snake and Gecko.
-
The difference between a four-legged snake and a gecko is:
1. Four-legged snake.
Generally speaking, the four-legged snake is actually a lizard, he has a large number of distributions in various parts of the world, which belongs to a typical cold-blooded animal, there are many species, at least more than 3,000 species, lizards can be terrestrial, semi-aquatic or burrowing in the soil, etc., the main thing to eat is insects.
Of course, the four-legged snake has such a special name, because it has a very close relationship with snakes, that is to say, it is similar to snakes in many places, and there are also some lizards, their reproduction mode is oviparous, although it is said that it is a minority, but there is also this special phenomenon.
Second, geckos. This creature is also known as a type of lizard, but in some places, it is also called a four-legged snake, its body is relatively flat, with some scales on its body, and they can quickly crawl on walls, ceilings, or relatively smooth places.
Of course, there are many species of geckos, at least 20 species, mainly distributed in some desert jungles or on the walls of inhabited houses.

Geckos have millions of extremely fine bristles on the bottom of each foot, and each bristle ends with about 400 to 1,000 finer branches, a fine structure that makes the bristles very close to the molecules on the surface of the object, resulting in molecular gravity.
Geckos have a very mixed diet, mainly live small insects, are beneficial and harmless animals, such as bread insects (where you buy birds), flies, mosquitoes, praying mantises, mealworms, bread worms, crickets, etc. are good feed for geckos, geckos do not eat much, eat a full meal for many days, and even do not eat for a few weeks and do not starve to death, geckos are very tenacious.

The gecko's ability to climb walls is superb. For many years, people have speculated that these structures are the suction cups and tools that it attaches to the wall and crawls on, based on the foot pads and undertoe scales formed by the gecko's enlarged toes (called flaps in the textbooks of Chinese teachers, and the bristles are branched into finer bristles, and the tips are swollen into shallow disc-shaped suction cups). In recent years, zoologists have observed the shallow disc at the bottom of the gecko's toe through an electron microscope and found that it is not a shallow disc with suction, but a dense row of bunches of microvilli on the foot pads and under the toe scales, which are only 90 microns long and 10 microns thick, they are like small curved hooks, which can easily grasp any small protrusions on the object and crawl effortlessly.
A gland has also been found at the tip of the microvilli, whose secretion apparently increases the gecko's adhesion when crawling. The gecko relies on these thousands of small hooks to move back and forth between walls and ceilings without falling off.

Nothing special is the feet, just different from other animals.

The differences between four-legged snakes and geckos are different distribution areas, different morphological characteristics, and different subjects.
