What is the difference between a four legged snake and a gecko?

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.

1.Gecko This product is in the form of flat strips, with a total length of 10 12cm. The head is oval and flattened, with a pair of eyes, and the back is black-brown, covered with fine scales; The thorax and ventral surfaces are yellowish-white, covered with larger scales.

2."Four-legged snake"Commonly known as lizard and skink because it has"Snakes"word, many people are afraid that Nabu will be poisoned after being bitten by it. In fact, the four-legged snake is neither a snake nor a bite.

3.The four-legged snake is about 20 centimeters long, and its tail is extremely long, accounting for about 2 3 of the total length. The habitat is also widespread, some live in the water, inhabit the desert, hide underground, climb in the woods, and even fly in the air.

1. The difference between four-legged snakes and geckos is different in distribution areas, different morphological characteristics, and different themes.

2. Different distribution areas: geckos are mainly produced in southwest China and south of the Yangtze River Basin; also distributed to Japan and South Korea; Four-legged snakes are mainly distributed in Fujian, Guangdong, Guangxi, Jiangsu, Zhejiang and other regions of China.

4. The snout scales are rectangular, with a pair of large nose scales on the upper edge and a small scale in the middle.

5. The chin scales are pentagonal, wide in front and narrow in the back.

6. Posterior chin scales, the smallest pair on the outside.

7. The ear piercing is small and oval, and the back of the invagination is covered with scales from the frontal, parietal, temporal, occipital to caudal base; The four-legged snake snout is sensitive and obtuse, and the snout is round.

9. The size of the nose scales, snout scales and head scales are different.

10. There is a tympanic membrane, which is covered with scales.

11. The eyelids are well developed and active, and the pupils are round.

12. The scales on the back and sides of the body are smaller.

13. There are scales on the back, and the scales become smaller and smaller as the back goes on until the tail disappears.

14. There are prismatic scales on both sides.

15. All are covered with scales.

16. Different themes: geckos belong to the lizard family; Four-legged snakes belong to the order Lepidoptera.

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

First, the distribution area is different.

2. Four-legged snake: all are covered with digging scales. snout obtuse rounded, snout length times the diameter of the eye; Nostrils in the scales of the nose**; nasal scales, snout scales; head scales vary in size and are all ridged; There is a tympanic membrane, which is covered with small scales; The eyelids are well-developed and motile, and the pupils are rounded.
