Newt and newt are members of the family Newt, with more than 60 species. All fire snakes are fire snakes, but not all fire snakes are fire snakes. According to the newt and newt lover's website CaudataCulture, there is little difference between newt and newt. Generally speaking, with some exceptions, salamanders spend more time in water than salamanders. In addition, the gender difference of salamanders is more significant.
The main difference between salamanders and salamanders is how to classify them. Newts belong to salamanders, spiny salamanders, naked-bellied salamanders, horned salamanders, chordates, epididymal salamanders and Pleurotus ostreatus. According to the Animal Diversity Network (ADW), the real salamander "belongs to Qiuglosha, Messala and salamander".
Newt with four legs and a long tail. Most people's skin is smooth and moist, although some species, such as salamanders with rough skin, have rough and granular skin as expected. Most species of salamanders have well-developed lungs, while some species of salamanders retain gills and are completely aquatic.
There are many kinds, and salamanders come in many different sizes. According to the Encyclopedia Britannica, they are usually less than 8 inches (20 cm). For example, a wart salamander grows to 7 inches (18cm) and weighs 0.22 to 0.37 ounces (6.3 to10.6g).

Some people live on land, while others live almost exclusively in water. For example, alligators live in swamps, forests, grasslands and farmland in southern Japan. The eastern red-spotted salamander is distributed in ponds, lakes and swamps in eastern North America.
Many salamanders move during the day, while others move at night. They spend most of their time foraging or wandering in the shade.
Their mating ceremony is particularly interesting. When mating season comes, males secrete a strong pheromone to attract females. Then it wags its tail and dances in the air. A study of Free University of Brussels 20 13 shows that this pheromone works very well. When the males are not around, females will try to mate with each other. [The pheromone of salamanders makes females fall into mating frenzy] An article in the journal Nature says that salamanders
Eye salamanders can regenerate fully functional limbs, organs and tissues, including cardiac muscle, components of nervous system and lens of eyes. The researchers hope that this ability is based on the same genetic feature, which can be found in all animals, even if it is potential. However, the research shows that because of the huge scale of the genome of salamander, it may not be that simple, and it is 10 times larger than the human genome.

Others use bright warning colors to indicate that they are toxic, can't cook well, and follow the tail culture. Newts "kdspe", "kdspe" and "kdspe" secrete a highly toxic mucus. 1966 A study published in the journal Poisonous Lizards found that at least 10 substances were called tartrazine and tetrodotoxin. Tetrodotoxin, or TTX, is the most toxic non-protein substance. According to tail culture, scientists know that this substance is similar to that in puffer fish culture. It is a powerful neurotoxin that can prevent the nervous system from sending signals to muscles. For example, it prevents your brain from sending heartbeat signals. The study of "KDSP" and "KDSP" found that the skin of a newt with rough skin was enough to kill 25,000 mice. The study also cited a case involving a man in Oregon who swallowed a salamander during an expedition (he drank a lot of wine at the time). After a few minutes, his lips began to sting. In the next two hours, he began to feel numb and weak, and then went through cardiac arrest. Later that day, despite being treated in the hospital, he died. "kdspe" kdsps was published in another study, published in the journal CopeIa 1974. The salamander toxin got into a stab wound on a scientist's index finger. His arm was numb for 30 minutes and entered his shoulder. Some of them were accompanied by nausea and dizziness. Some salamanders are even worse. In addition to secreting toxins, Spanish salamander and crocodile salamander will also pierce the ribs into the skin and pierce the victims to ensure that the venom enters the attacker. KDSP diet KDSP salamanders are carnivores. They eat the eggs of slugs, worms, small invertebrates, amphibians and land insects. Tadpoles, shrimps, aquatic insects, insect larvae and mollusks are all on the menu in the water. Young salamanders called larvae can feed shrimp and insect larvae they find while swimming.

For example, according to National Geographic, the wart salamander can lay 200 to 300 eggs. However, according to a-Z animals, they put them on aquatic plants one at a time. On the other hand, frogs lay eggs in groups and float near the water. Some salamanders lay eggs on land.
Newt babies are called tadpoles, similar to young fish with feathered outer gills. Like frogs, salamanders will evolve into adults. Some from eggs to larvae to adults, and some from eggs to larvae to larvae to adults. According to the Integrated Classification Information System (ITIS):

In two space missions 1994 and 1995,
The embryonic development of Japanese red-bellied salamander was studied by using longicorn beetle. According to the research published in Space Biology, the female "longicorn beetle" was induced to lay eggs in orbit. Eggs are exposed to
