In winter, the temperature drops sharply, and it is at this time that all kinds of creatures will use some of their survival skills in order to survive the cold smoothly, in order to find some life in this long winter, and also to lay the foundation for smooth reproduction after the end of the cold winter.
Cold-blooded animals such as snakes will choose to hibernate at this time, mainly because their body temperature cannot be regulated by themselves, which is their biggest defect in winter.
Snakes enter a state of hibernation only to avoid freezing to death due to the cold weather in the cold winter, and a large part of the time in this state is not conscious, and will not even react, which leads to the mice can be safely "slaughtered by rats" during this period.
However, in the spring, these snakes begin to wake up and quickly return to their state, as their reserves are depleted during the winter months, so they quickly seek out food to replenish their energy.
And many rats have caught many snakes during this time, so when the snakes wake up, they will quickly look for these rats to catch.
Therefore, there is such a saying, "Snakes eat rats for half a year, and rats eat snakes for half a year".
So do snakes really be slaughtered by rats?
And why do we have to hibernate?
Snakes are cold-blooded animals, and their body temperature cannot be regulated by themselves, so in this world with four seasons, they need some protection measures to cope with these seasonal changes.
Because of this, snakes have evolved to hibernate to alleviate their disadvantage in cold environments.
Reptiles such as snakes appeared very early on the earth, and their ancestors can be traced back to the Mesozoic Era, 150 million years ago, when reptiles first appeared on the earth, and snakes evolved from these animals.
In the process of evolution, these reptiles gradually lost their ability to be homeothermic animals that had certain advantages over mammals at that time, due to the limitations of environmental factors, and underwent a major change, which also gave them obvious cold-blooded animal characteristics, and their body temperature could not be regulated by themselves.
And this trait has also caused great trouble for these creatures in the process of evolution, especially in the cold winter months, and it is in this situation that snakes evolved.
The primitive characteristic of snake evolution is that there are no organs in the body that can regulate temperature, and this has become more and more obvious in the process of snake evolution, and even snakes, which have undergone many changes in evolution, still do not have any organs that can keep them out of the cold.
In the organism, when the temperature drops to minus 5 °C, the organs in the body will gradually stop functioning, or even until it stops, at this time, snakes will not be able to maintain their life activities, so they will enter a state of hibernation.
