Which sun snake went into the hole?

Whenever winter comes and the temperature drops to 7-8℃, snakes begin to choose caves, tree holes and crevices in high drought areas as shelters and enter hibernation. When hibernating, there are often dozens or hundreds of snakes of the same or different species clustered together.

Why do snakes hibernate collectively? Because snakes are cold-blooded, the temperature in their bodies will change with the ambient temperature. In winter, when the outside temperature drops, the snake's body temperature also drops. So snakes choose

Hibernate to adapt to the low temperature environment. During this period, snakes can't eat or move, and they can only maintain the minimum needs of life activities by consuming the fat stored in their bodies before winter comes. In such a harsh natural environment as winter

The mortality rate of scattered and hibernating snakes is as high as 1/3 to 1/2. If overwintering in groups, the ambient temperature 1-2℃ can be increased and the water loss can be reduced.
