Scientists have discovered the smallest reptile in the world, what is a reptile?

It is reported that it was discovered by German scientists in northern Madagascar, the smallest reptile is a magical chameleon subspecies, it is understood that their size is only the size of a melon seed, can lie on human fingers, and according to the Bavarian National Zoo in Munich, they found two adult miniature chameleons in northern Madagascar, a female and a male, among them, the male body length is 22 mm, is the smallest reptile currently known, and the female is larger than the male chameleon, with a total length of 29 mm. <>

The so-called reptiles, also known as reptiles, evolved from ancient amphibians at the end of the Carboniferous period, and are ectothermic vertebrates adapted to terrestrial life, and are called amniotes together with birds and mammals. In fact, reptiles and amphibians, do not have a perfect thermal insulation device and body temperature regulation function, also called it "external heat source animals", the existing reptiles in the world are divided into the following categories: Linda, turtles, crocodile reptiles and amphibians and reptiles, among them, Linda includes a variety of snakes and lizards with Linda; Turtles are also divided into turtles, turtles, turtles and turtles. Crocodiles and reptiles with crocodiles include Chinese alligators, bay crocodiles, Nile crocodiles and other reptiles; Amphibians and reptiles are also primitive terrestrial vertebrates.

In fact, the world's smallest reptile appeared in northern Madagascar, and researchers said that they did not know why the species was so small, which may have something to do with the "island effect", or maybe there is another cause, which needs to be investigated. However, in reality, the living environment of this species is similar to that of other endangered species, the habitat of this chameleon has also been destroyed, human deforestation has led to the decline of forest cover, the deterioration of the forest environment, etc., fortunately, the relevant ** timely took protective measures, planned a protected area in the local area, therefore, this chameleon has the conditions to survive. <>

In the face of new species being discovered again and again, and new environmental problems are being thrown, should we think more about how to protect our living environment and reduce the extinction of species?

That's my personal opinion, thank you.

The chameleon subspecies, which can crawl on its fingers, is indeed very miniature, and such a small naked eye may not be able to see clearly.

The reptile discovered by scientists is a male and a female two chameleons, a reptile is an animal that crawls or moves with its abdomen or short limbs, belonging to the tetrapoda amniotic family.

A few days ago, German scientists discovered a miraculous subspecies of chameleon in northern Madagascar, which is only the size of a melon seed and can lie on a human finger, and may be the smallest reptile on earth. Females are millimeters long, while males are only millimeters long.

The snapping turtle is the oldest living reptile and one of the largest freshwater turtles in the world.

1. It is known as the king of freshwater animals, which is divided into two categories, commonly known as predators and small crocodiles.

Reptiles are mainly divided into four main groups: turtles, beaks, scales (lizards, snakes), and crocodiles. Turtles and turtles are the oldest group of reptiles living on Earth.

It is almost a reptile of the same age as the dinosaurs, and its evolution is extremely slow, and it is a reptile that lives on land, water, and in the ocean. Turtles that live on land have thick limbs and blunt claws. Sea turtles, on the other hand, have pulpy limbs that are suitable for swimming, and they all have hard shells to protect their internal organs.

Beak leader, is a primitive terrestrial species. The outside of the body is covered with fine scales, and the beak is long like a bird's beak, so it is called a beak-headed lizard. There is only one remaining species of this order, which is found in New Zealand.

Lepids are a group of terrestrial, aquatic, arboreal and burrowing groups, and are the most numerous and diverse group of reptiles. It is distributed all over the world. Lizard suborder is a small and medium-sized reptile, in this group, the largest is the monitor lizard, up to 4 meters long, weighing 25 kilograms, the smallest is the gecko is only 3 4 millimeters, more than 10 grams, but they also occupy an important place in nature.

The suborder snake, as small as a millimeter and as large as 11 meters, burrows and climbs, it is characterized by a high degree of myopia in the eyes, but the tongue is a very sensitive chemical detector that can detect changes in chemicals in the surrounding air. There are many kinds of them, poisonous snakes and non-venomous snakes, there are aquatic snakes and terrestrial and arboreal snakes, as well as land, tree, water, and three-way snakes.

The smallest reptile on Earth is the chameleon.

German scientists have discovered a miraculous subspecies of chameleons in northern Madagascar, which are only the size of melon seeds, can lie on human fingers, and may be the smallest reptile on earth. The Bavarian State Zoo in Munich, Germany, said it had found two adult miniature chameleons, one female and one male, north of Madagascar.

The male is only 22 mm long, making him the smallest known reptile at present. The other female chameleon is slightly larger, but its overall length is only 29 mm. Researchers say it's unclear why the species is so small, but perhaps similar to the "island effect," animals that are trapped on islands and have small habitat areas tend to evolve smaller sizes.

However, the habitat of this new species is worrying, and the chameleon's habitat has been destroyed by deforestation, but in recent years** they have been lucky enough to survive by planning a local protected area.

Chameleon introduced

The body length is 15 25 cm (7 10 in) longer, and the longest is 60 cm. The body is long and cylindrical, flattened on both sides, the head is triangular, and the tail is often curled. The eyes are protruding and can be rotated independently.

Some types of heads are helmet-shaped, while others have conspicuous headdresses such as three long horns protruding from the front.

Males are more prominent and may be used to defend their occupied areas. If there are other males into the stool sail, the dominant male's body is stretched, the throat is bulging, the head hair ornament is erect or shaking, if it still cannot scare the other party, rush over and bite his palate.

The largest reptile is the bay crocodile, the bay crocodile is also known as the estuarine crocodile, saltwater crocodile, Malayan crocodile, man-eating crocodile, the adult body is generally 3 6 meters long, the longest can reach more than 7 meters, the largest weighs more than 1600 kilograms, is the largest in existence.

of reptiles.

Saltwater crocodile. The saltwater crocodile is the largest living reptile in the world, with a body length of more than 6 meters. These carnivorous behemoths are capable of crushing the skull of a cow and can easily eat a person.

The areas with the highest crocodile populations in Australia are clearly marked so that people can avoid areas frequented by crocodiles before they become crocodile treats. The distribution of saltwater crocodiles ranges from Southeast Asia to Australia. As their name suggests, they are even able to live in the ocean and have reached as far away as the Sea of Japan.

Recently, scientists discovered 3354, the smallest reptile on Earth. Two adult miniature chameleons, one female and one male, have a body of only 22 mm, and the female is slightly longer, but also only 29 mm. Although two small animals have been found, their survival is still worrying.

Their habitat has been destroyed. Later, in order to protect the environment, they survived through local planning. Two small chameleons were found in northern Madagascar.

Scientists have found that the male, the smallest reptile on Earth, is only 22 millimeters long. Because it is small, it can lie directly on a person's finger. This pair of mini-chameleons are the smallest reptiles known, and chameleons have always been full of mystery.

Why they can change the color of their bodies at will has not been revealed until now. The discoloration of the chameleon does not change the concentration of pigment in **, but relies on the special structure of ** volt height to reflect light.

The discoloration of chameleons can only be successful in adulthood. In order to reveal the secret of the chameleon, scientists have used various methods, and after many experiments, the secret of the chameleon has finally been revealed. The chameleon's ** has rainbow-colored cells in it.

In these iridescent cells, many nanocrystals have different shapes. The arrangement of these nanocrystals can be changed by chameleons, so the color can also be changed. In addition to these iridescent cells, chameleons also have a thick layer of cells to maintain the temperature.

Now scientists have discovered the smallest reptile on Earth, and this is exciting news. From the discovery of microbial chameleon events, it can be seen how much the environment affects living things. After the discovery of new species, their survival is also a concern.
