Frogs are amphibians. From the aspect of whether their body temperature will change with the changes of the outside world, frogs are still temperature-changing animals, because their body temperature is not constant all the time, but changing. When the outside temperature changes, the body temperature of frogs will also change to some extent. This makes frogs hibernate in winter. Especially when the winter temperature in the living area of frogs is very low, they basically go into hibernation. Frogs usually hibernate in caves, which can protect them from being eaten by other animals and to a certain extent can resist severe cold. When spring comes again, frogs will gradually come to Allen Su.

As mentioned above, frogs go into hibernation in winter. The main reason is that the frog's body temperature is relatively low at this time, which makes it difficult to maintain them to carry out various normal life activities. When winter comes, the temperature will keep dropping. Because frogs are temperature-changing animals, their body temperature will change and become lower. Frogs' activity will also be affected by their body temperature, so they can't keep active. At this time, in order to survive and resist the surrounding cold, they can only find a safe place to get in for the winter. During this period, they are not active and consume less.

Another important reason is that frogs can hardly find food at this time. In winter, when the temperature is low, many insects can't survive, so frogs lack food to eat. At this time, they can only hibernate and reduce their energy consumption, otherwise they may starve to death. Of course, they also try to eat as much food as possible before going into hibernation.
