is the salamander? The salamander refers to an animal belonging to the genus Salamander of the family Salamandridae of the order Caudata of the class Amphibia of the phylum Chordata, which belongs to vertebrates and amphibians. The head of the salamander is relatively flat and the tail is relatively long, which is generally shorter than the total length of the body and head. Their limbs are of moderate size, with four fingers on their forelimbs and five on their hind limbs. Hynobius salamander contains many species, there are more than 40 species in the world, and there are some differences between these different species. Hynobius salamander is mainly distributed in China, Russia, Korea, Japan and some Central Asian countries.
Salamanders generally live in slow-flowing rivers or streams, and may also inhabit hidden caves. From the point of view of feeding habits, salamander belongs to a carnivorous animal, small fish, earthworms, tadpoles and other animals may become their food. Wild salamanders are relatively strong in predation, sometimes in water and sometimes on land. From the point of view of reproduction, salamander uses oviparous reproduction, which is the same as most amphibians.
? As mentioned above, the salamander is an animal in the amphibian class, that is, an amphibian in the classification. It can be seen that salamander, as an amphibian, can not belong to mammals at the same time, because mammals are mammals in the class of mammals, and amphibians are two independent classes, and there is no intersection between them.
Moreover, as amphibians, salamanders are different from mammals in many characteristics. From the point of view of reproductive mode, the reproductive offspring of salamanders are oviparous, while mammals are basically viviparous. For example, from the way of breathing, mammals breathe with their lungs, although salamanders can also breathe with their lungs when they grow up, but because their lungs are not developed, their breathing efficiency is far lower than that of mammals.
