There are many types of newts, which ones do you know?

There are many species of salamanders, some are protected and some are not, salamanders, salamanders, there are about 400 species in the world, belonging to 10 families under the order Cerda, including the northern newt, the salamander, and the great cryptogill salamander (a large aquatic salamander). They mostly inhabit freshwater and marshy areas, mainly temperate regions of the Northern Hemisphere. The salamander has a short body, 4 legs, **damp, about 10-15 cm in length, and most of them have bright colors and conspicuous appearance.

The Chinese giant salamander is the largest, with a body length of up to one meter.

Among the newt species are salamanders, which are representatives of the fire element, can tolerate high heat, can spit fire, and can even live in magma, and some samurai will risk defeating them in order to strip their bodies of precious skins that can resist fire to make shields or armor. Salamanders have a very cold body, not only are they not afraid of fire, they can also put out fires, and they know how to use fire to attack their opponents. Salamanders' body fluids are highly toxic, and if a person eats the fruit that the salamander crawls on, he will be poisoned to death immediately.

Among the species is the salamander, which mainly eats insects, worms, snails and some small animals, including their kind. Like other amphibians, they are kept on ** to absorb and therefore need a humid living environment. When the environment reaches minus zero, they go into hibernation, and most adult salamanders hide during the day and come out to feed at night.

Some do not emerge from the ground until the breeding season, or when the temperature and humidity are suitable for their survival.

Learn a little about the salamander, a class of amphibians that evolved in the mid-Jurassic period. There are about 400 species alive today, and they live in freshwater and moist woodlands, feeding on snails, insects, and other small animals. Some species of salamanders, especially those of the family Axolotlidae, are entirely terrestrial and spend their days away from rivers and ponds.

Salamander, a small, bright white fire-breathing lizard, feeds on flames. If pepper is fed regularly, it will be able to survive outside the flame for 6 hours. A salamander spews sparks, runs along the flames and smoke, and escapes into the fire.

Its color varies depending on the temperature of the flames it emitts, taking on the color of scarlet or blue. Salamander's blood is an elixir that helps with ** and recovery.

The salamanders that you know from reading books, after they are born, generally have to go through the larval stage, which may be a few days or several years. The larvae have external gills and teeth, and no eyelids. These traits may be retained until sexual maturity.

This trait is found in both the mud salamander that inhabits eastern North America and the salamander that lives in central Mexico.

1. Newt genus: 4 species are known in China, namely Chinese newt, Hong Kong newt, tailed spot newt, and Guangxi newt.

2. Acanthosaurus: There are 3 species known in China, namely Ryukyu acanthus, Zhenhai acanthus, and fine mole acanth.

3. Oxid: There is only one species.

4. Wart newt: 6 species (subspecies) are known in China, namely Hainan wart newt, fine mole and verrucous newt (named subspecies, Wenxian.

subspecies), Great Liang colocous newt, Guizhou corucous newt, red mute newt.

5. Salamander: 6 species (subspecies) are known in China, namely the Oriental salamander.

Chaoshan salamander, blue-tailed salamander (named subspecies, Chuxiong subspecies), Chenggong salamander, alpine spiny newt (newly discovered).

The salamander has a plump, cylindrical body, much like a reptilian lizard, dragging a long, side-flat tail. They are moist and sticky, and their bodies are unusually bright in color – they have distinct markings or cockscomb-like protrusions. Salamanders have short limbs and webbed feet.

Adults have eyelids and are motile, but juveniles have no eyelids.

Axolotls all have tails and are similar in shape to lizards, but have no scales on their bodies. Unlike frogs, it has a long tail throughout its life. Salamanders have poor vision and rely mainly on their sense of smell to hunt, feeding on tadpoles, frogs, small fish, babies, and daphnia.

Aquatic types lay eggs in the water, terrestrial types return to the water to lay eggs during reproduction, and a few species lay eggs on wet land, and the larvae develop and grow in the water after laying eggs. Males are slightly smaller than females; The male body is lively and sensitive, and the female body has a hypertrophied abdomen and is slow to move; The male cloaca pore is raised, especially in the reproductive season, the hole is long, there is a distinct villous papillae, and even protrudes outward, while the cloaca pore of the female is flat, the hole fissure is short, and there is no obvious papillae. In the process of raising salamanders, it will be found that it has molting.

Note that the salamander slowly sheds its outer skin at the top of its head, followed by its trunk, limbs, and tail. The skin shed by the salamander is sometimes devoured by itself and sometimes eaten by its companions.

The basic characteristics of the oriental salamander: a small salamander, generally only 6 10 cm. The color of the back is usually black, but there are also individuals with greenish, grayish, or dark spots.

The back** is smoother. The ridges are not very prominent. The abdomen is orange-red with black spots, and there are very few without dark spots.

The end of the tail is rounded and blunt (male) or pointed (female), and the lower edge of the caudal fin fold is all orange-red. The toes of the limbs are thinner.

The basic characteristics of the red-bellied salamander: the body size is generally about 9 13cm. The back is available in a variety of colors, including black (some types have orange spots), yellow-green mixed with black spots, etc.

The ** on the back is rougher, the ridges are more pronounced, and one type of ridges is orange. Protrusion of the glands behind the ear. The lateral edges of the body are distinct.

Most of the abdomen is orange with dark spots, and some types of abdomen are black on both sides with orange honorific in the middle and fine white, orange, and black spots. The tail end is pointed. The lower margin of the caudal fin fold is mostly orange, the hind half to the end is black, and the upper margin is orange or dorsal (different subspecies).

Males have a blue tail with dark spots during the breeding season. The toes of the limbs are thinner.

Salamanders, also known as salamanders, are amphibians and not very common creatures.

The salamander is an endangered salamander of the salamander family Axolotlidae, which is widely distributed in warm freshwater and swampy areas around the world. Axolotls are amphibians with tails that resemble lizards in appearance, but have no scales on their surfaces. Axolotls mainly feed on insects, worms, snails and other small animals, and are good ornamental animals, including the northern salamander, salamander, and salamander (a large aquatic salamander).

Habits

From the perspective of diet, salamanders are carnivores, and the food they eat is mainly some relatively small animals, such as small fish, tadpoles, frogs, and water fleas. When salamanders hunt, they rely mainly on their sense of smell because of their poor vision.

Salamanders reproduce oviparously, and their breeding season generally begins in February, with May being at its peak. At this time, they will lay eggs into the water, and the number of eggs laid at a time is relatively large.
