The temperature of snakes’ bodies changes according to the seasons. How do snakes survive the winter?

Generally speaking, the body temperature of snakes will change according to the changes of the seasons. The active period of snakes is the period when snakes ingest food and reproduce. When the temperature is relatively low, snakes will look for drier caves, crevices in rocks, or prepare to sleep in tree holes. For snakes, it is an adaptation to low-temperature environments, which is caused by the low-temperature environment. A dormant state.

Snake is equivalent to other animals, so the structure and function of its tissues have not changed much compared to before. The heart has only one ventricle, and its skin lacks the function of keeping warm. It cannot grow feathers on its epidermis to form a layer of insulation like those higher birds. This reason makes snakes particularly susceptible to interference from outside temperatures. Therefore, it is called a cold-blooded animal. When the weather comes When it gets cold, the snake's body temperature will decrease as its body temperature decreases. As long as the snake cannot maintain its body temperature at a certain height, it will have no choice but to find a place to keep warm and hide.

According to the analysis of the detection, snakes will eat less when the temperature is 5 degrees Celsius. Most snakes will choose to migrate. When the outside temperature is 6 to 8 degrees Celsius, snakes will After stopping other activities, if the temperature still drops, the snake will fall into a state of paralysis when it drops to 2 to 3 degrees Celsius, that is, it will be frozen. If the snake's own body temperature drops below -2 degrees Celsius or the temperature of the external environment drops below -5 degrees Celsius, the snake will directly freeze to death.

The cooler the climate becomes, the less able snakes are to eat. When the temperature is not too low, snakes will have a meal in advance, and then prepare to enter the place they find to start sleeping mode. It is a kind of social animal, so there are usually dozens or even hundreds of them in the same dry tree hole or cave.

When it gets warm, the snakes will wake up from their dormant state and start a new life!
