is a salamander? A salamander belongs to the amphibian class of the phylum Chordata. It is a vertebrate and an amphibian. Some stages are active in water, while others are mainly living on land. The salamander's body is cylindrical in shape, with no scales on the surface and moist skin. Their tail is flat and long, which is one of their outstanding characteristics. They also have limbs, but they are shorter. There are many species of salamanders, which are widely distributed in the world, including Asia, Europe, Africa and the Americas. There are also some species of salamanders in China, which are mainly distributed in the subtropical areas of China, that is, the south. Some salamanders are distributed from the Qinling Mountains south of the Huaihe River to the more southerly province of Guangdong.
In terms of feeding habits, salamanders are carnivores, and their food is mainly small animals, such as small fish, tadpoles, frogs, water fleas and so on. When salamanders hunt, they rely mainly on their sense of smell, which is due to their poor vision. Salamanders breed by laying eggs, and their breeding season usually begins in February and peaks in May. At this time, they will lay eggs in the water, and the number of eggs laid each time is relatively large.
above, salamanders are amphibians in the class Amphibia. From the point of view of whether the body temperature changes, amphibians have a common feature that their body temperature will change with the change of external temperature. So do salamanders, which are also poikilotherms. Therefore, when the temperature drops in winter, their body temperature will change accordingly, and the requirement for their activity is very great. When it's very cold, the salamander goes straight into hibernation.
Generally speaking, the temperature begins to drop from October, when they slowly begin to enter a dormant state. It is not until March of the following year, when the temperature begins to rise, that they will slowly wake up. During this period of hibernation, salamanders usually live in rock crevices or under boulders.
