How do snakes survive the winter?

Snakes are not common in life, and it is very difficult for friends who live in commercial housing to get face to face with them. But we all know something about it, so how do snakes survive the winter? Let's have a look together!

How do snakes survive the winter

Snakes hibernate in winter. It takes about three months from burrowing to hibernation, which mainly depends on the slow replenishment of nutrients stored in the body in the form of fat so as to maintain a minimum amount of nutrients for daily life.

Second, the living habits of snakes

1. The snake is a kind of temperature-changing animal whose body temperature changes with air temperature, because the snake itself does not have a perfect body temperature regulation mechanism to produce and maintain a constant body temperature.

2. The optimum temperature for snake activity is 20-30 ℃, in which the growth rate of snakes increases linearly with the increase of air temperature. For example, the results of one study showed that the monthly weight gain of adult cobras was 64.7,72.7g and 94.3g respectively at 18 ℃, 23 ℃ and 28 ℃. But more than 35 ℃ will lead to anorexia and illness, and more than 40 to 45 ℃ will die quickly.

3. Air humidity also has a great influence on snakes, which is generally 50% to 70%. Too high is easy to suffer from mildew, pneumonia, etc., and the mortality rate is higher in the south; too low (such as the northern spring drought) is not conducive to molting (especially pregnant snakes) due to rapid evaporation of water, affecting its continued growth and even causing death. "Snake aisle, heavy rain" is also the result of low pressure and high humidity before the rain, and the snake feels uncomfortable running around.
