When does the snake wake up from hibernation?

Snake 165438+ 10 hibernates in October and wakes up in April.

Snakes usually hibernate from 1 1 in the first year to April in the second year. The duration of hibernation depends on the length and severity of the cold season. With the increase of geographical latitude, the hibernation period of snakes is prolonged. The hibernating time of the same snake is different in different areas, and the hibernating sequence of the snake is also closely related to the species, sex and age of the snake.

Brief introduction of snake hibernation

Before hibernation, in1October and11October, all kinds of snakes are foraging everywhere, eating fat and strong, and after accumulating sufficient nutrition in their bodies, they choose to live in dry and warm caves and enter hibernation. In the initial sting, if the weather gets warmer, some snakes will still come out of the hole and move around it.

During the whole hibernation period, all kinds of snakes can't eat or move, their bodies shrink into a ball, their body temperature drops, their metabolism drops to a minimum, and they can survive the long winter by relying on the nutrition they ingested before hibernation. From April to May of the following spring, snakes wake up after the weather gets warmer and then return to nature.

Snakes like to live in groups when they hibernate, and often there are as few as 35, as many as dozens or even hundreds in a hibernating cave. As winter approaches, snakes have the instinct to gather together. Sometimes several kinds of snakes will live together in a cave, and the reason is not the lack of a suitable hibernation place.

An obvious advantage of this group behavior is that many snakes will expose less surface area when they are crowded together than when they hibernate alone, so they can save a little more heat in their bodies. Social snakes can also raise body temperature 1~3℃.

In order to increase the temperature during hibernation, they sometimes live in the same cave with their opponents (such as mice, frogs, toads and other animals), which can be described as "enemy and me."
