They seem dirty and slow, which most of us don’t like, but they are part of the ecosystem and help create an ecological balance. They are salamanders. They belong to amphibians, so they can live not only on land, but also in water. About 5,000 species of salamanders are known today. They have a slender body, a strong nose and a long tail.
All fossil species have been subdivided into the order Caudata and the animals into the order Urodela. The forelimbs have 4 fingers and the legs have 5 fingers. The skin is perfectly adapted to live not only on land, but also in water. Some were in the water, some were on the ground, some were in the water, and some were on the ground. Energy or regeneration is highly developed.
Older salamanders resemble lizards on the body, but some have eel-like bodies with lower limbs. No claws at all. They also have bright colors every year, and some just change to bright colors for males when giving birth. Some prefer soil, no skin pigmentation, and may have white or pink bodies. Some small ones, like the lesser salamander, are only 2.7 cm long, while others are as tall as the great Chinese salamander, which can reach 1.8 m and weigh up to 65 kg. Most species are 10 to 20 cm long. They are known to grow their skin and eat flaky skin.
Breathing patterns also vary from type to type. Some breathe through the gills without the lungs. Gills can be seen as hairs on both sides of the head, and amphibians have internal gills and gill slits. Although terrestrial bacteria respire with lungs, the structure of lungs is very simple compared to that of animals. Olms have gills and shrubs.
Some species lack both gills and lungs and breathe through the skin called valerian respiration, with multiple layers of capillary breakage throughout the epidermis around the mouth. Some people with pneumonia also breathe this way. The skin secretes a lot of mucus to keep it moist as it moves through dry soil. Spit not only helps balance salt water, but it also acts as a lubricant during swimming. Tumors also secrete toxins and pheromones when talking. The tip of the tongue is also held back with the mucus which helps it capture the animal.
Some aquatic animals do not have muscles on their tongues, so they cannot be used to catch animals. Most species have teeth on the upper and lower jaws. They use three-color vision in the ultraviolet range to capture animals. Subterranean salamanders have reduced visual contact with skin. Some aquatic species have fish-like organisms that log on to monitor changes. No outer ear, no middle ear. The tail drops when attacked by a predator. The predator is then regenerated by the automatic cutting process. Members can be regenerated.
They are found in every country except Antarctica, Australia, and most of Africa. A third of these animals are registered in North America. Appalachia is home to some of the largest salamanders in the world. Salamanders prefer to live in dry, arid areas of the northern hemisphere. They are found in canals, lakes, canals and other wetlands.
The life cycle is similar to that of frogs and toads. Fertilization in most species is male fertilization, in which male sperm deposits are contained in a sac-like structure within the female cloaca. The females are oviparous and lay their eggs near the pond or in moist soil. Oviparous species are also known. The eggs are all water or whole soil and hatch into long-gilled larvae.
Larvae may or may not have branches. The larval period varies from a few days to several years. Some do not have the larval stage. Neoteny has been found in many salamander species that retain gills even after their larval growth. Axolotl larvae of tiger salamanders are an example of neoteny.

Salamanders are resistant to fungal infections called chytridiomycosis which cause population decline. Behavioral loss due to deforestation is also one of the main reasons for population decline. There are 10 families according to the order of Caudata.
Many myths and legends are famous for them. They are often seen as symbols of fire. People believe they are in the logs and try to get out when they catch fire. People believe they come from the flames. They deserve a special place in the writings of Leonardo da Vinci.
