What kind of animal is a black body with a tail on the back, a four legged animal, and a gecko?

A very common species of reptiles.

It is also the joy of children, this reptile is not only not ugly or hideous, but it still looks clear and beautiful, plus its own non-toxic character is docile. It has become a toy for children, and this reptile becomes more and more active as the weather gets hotter and hotter, and it is often seen lying motionless on the side of the road and farmland under the summer sun. It looks like a lifeless piece of dirt, but with the slightest movement, the thing will run as fast as it flies.

It looks like it's flying from the ground.

This reptile is commonly known as the "pig snake", which is the famous four-legged snake.

The scales all over the body do look like snakes. Four-legged snakes are actually lizards too.

One of them, not very good at running. It is widely distributed and can be found in farmland, beaches, trees, and hillsides. Because it looks very similar to a snake, all the folk believe that it is related to the snake, because of the claws, so the generation is higher than the snake, the folk is commonly called:

Aunt Snake, which means the aunt of the snake, is a cut higher than the age of the snake, because the homonym of the aunt is easy to call the mother of the dog, so some places also call it: the mother of the dog.

？A chameleon gecko with blind eyes and a broken tail.

A color-changing gecko with one eye and a broken tail.

Isn't it the following one? This is a salamander called the Oriental salamander.

Oriental salamander. Oriental salamanders are amphibians.

There are animals of the order Cerdae, the salamander family, and the salamander genus, because they are amphibians.

So it can live both in the water and on land.

The Oriental salamander is not large, that is, 6 8 cm long, with a flat head and a head that is longer than the width of the head. **Smooth, black on the back, limbs and tail, red on the ventral surface.

The Oriental salamander lives in mountainous areas at an altitude of 30 1000 m above sea level, and often inhabits streams, muddy swamps, still ponds, spring pools, and water ditches in and near rice paddies. It is distributed all over the southern part of China.

The oriental salamander is poisonous and highly toxic under the skin, called tetrodotoxin.

It is the most toxic toxin found in the world, one milligram can kill an adult, and the toxin is under the skin and generally not released.

It should be a lizard. The body of lizards is generally divided into four parts: head, neck, trunk, and tail. The epidermis of the body is leathery scales, and some species also have small bony plates under the scales, such as skinks and snake lizards. Lizards have small teeth, and the shape and length of their tongues vary depending on the species.

The eyes are more developed, some species also have cranial parietal eyes, except for most geckos, the eyelids are motile and motile in general, and the burrowing type of eyes are mostly hidden under the skin. Its ears and tympanic membrane are mostly exposed, and the tympanic membrane is well developed.

The left and right mandible bones are united by bone sutures, so the mouth should not be opened too wide. Most lizards have limbs, but some have only forelimbs or hindlimbs with claws at the ends of their fingers and toes. There is a sternum.

There are many types of lizards, and their morphological characteristics vary greatly. Among the common lizard species, the golden snake is 16-22 cm long and has a slender tail, which accounts for 2 3 of the body. The length of the trunk of the grass lizard is up to 6 cm, the length of the tail can reach 2 3 times the length of the trunk, and the back is mainly brown with obvious protrusions on the scales.

There are many species of iguanas, with tooth-like scales on the surface of the body and spiny protrusions on the back. Some species of iguanas have a pouch in their throats. Chameleons change color depending on their surroundings, with tongues that extend beyond their body length and paws and tails that are conducive to climbing.

Skinks are the most well-known of the lizards.

The body is long, cylindrical, with a pointed nose, a long tail, thin and smooth scales, and legs so small that they are barely visible. The Lithosaurus is medium in size, active in personality, and adaptable. There are many species of geckos, and their body characteristics vary greatly.

Most of them are small, with flat bodies, short limbs, large, protruding eyes that cannot be closed, and millions of hair-like fine cilia grow at the tips of their toes, and in groups of thousands, so that their toes have a great adsorption force, making them good at climbing.

Zebrafish can regenerate fins, scales, and even part of a heart. Spiders can regenerate severed limbs. Tadpoles can regenerate tails, but not when they become frogs. Like earthworms, sea cucumbers are cut off in parts, and the cut off parts can grow into other sea cucumbers.

It is necessary to look at the neck bones, eyelids, claws and other parts to make a final judgment.

Skinks are more likely, and my family is called Horse Snake.

First of all, to clarify, the body surface light is not smooth and the size and color are not the characteristics that distinguish geckos from lizards, and geckos are just some species of lizards. You should come across a skink or a slippery lizard.

Maybe it's the Earth Dragon, which is often found in the mountains.

In the grass or beside the stone mill in the rural fields, a small animal with a slender tail and a fast crawling speed can often be seen, which is the lizard skink family commonly known as the four-legged snake.

Speaking of the four-legged snake, because it has the word snake, many people are afraid of being poisoned after being bitten by it Actually, the four-legged snake is neither a snake nor a bite.

The four-legged snake is commonly known in Zhejiang (mountain loach, big-bellied mantis, snake loach).

Lizards and skinks are mainly distributed in Fujian, Guangdong, Jiangsu, Zhejiang and other regions of China They are agile, generally active during the day, often in and out of the grass, stone piles and roadsides, and when disturbed, they quickly run to a nearby hidden place to hide.

The tail of the gecko resembles that of an earthworm.

Because the gecko has a smooth articular surface in the tail vertebrae of the gecko, connecting the front and back half of the tail vertebrae, the muscles, **, and scales in this place are relatively thin and loose, so when the tail is attacked, it can swing its body violently, and through the strong contraction of the tail muscles, the tail vertebrae are broken at the joint surface, and the tail has a strong amino acid liquid Once it touches the mucus, the tail will be quickly broken.

There is also a liquid drug called kilasin in the tail of the gecko, which is naturally present. Therefore, if the gecko's tail is caught by something, it will turn upside down on its own, resulting in tail breakage, thus achieving the role of saving life. As for the growth of new tails, it is because the tail elements melt and dissolve, and it will take about 2-3 months to grow a longer new tail.

It's a bit chubby, supposedly like wool. And the gecko tail can be used for self-protection. When pulled by external forces or encountering enemies, the tail muscles contract strongly, which can cause the tail to fall off.

The section that falls, because the nerves and muscles are not dead for a while, will also vibrate on the ground for a period of time to divert the attention of the "enemy".

Think of snakes, or crocodiles.

Geckos look like lizards, are completely harmless to humans, and belong to the gecko family. There are about 750 species of geckos in the world, belonging to about 80 genera. Geckos are small and mostly nocturnal reptiles.

**Soft, short and sturdy body. The head is large, the limbs are small, and the toes are mostly extended and have suction cups. Most geckos are between 3 and 15 centimeters long, including the tail, which takes up half of its body length.

Geckos are highly adaptable to their environment and have their footprints from deserts to jungles. There are many species of geckos that interact with people. Geckos feed mainly on insects, which is valuable to humans.

The suckers of the geckos' toes have many small hooks that look like hair.

With these physiological structures, geckos can crawl on vertically smooth or even smooth ceilings. Most geckos have a clear protective film over their eyes. The pupils of a common nocturnal gecko are erected.

It is oval in shape. Their tails may be long and pointed, short and blunt, or bulbous. Some geckos' tails are also their nutrient storage rooms, and when they are not eating or drinking, they can extract nutrients from them.

Geckos' tails can be easily disconnected and can grow back, which is also a good way to get out of the gecko's way of getting out after being caught.
