Natural phenomena in winter:

Why do some animals hibernate and some don't?

When people dig in the cold winter, they often dig out one or several dead snakes, which are hibernating snakes. Besides snakes, turtles and frogs hibernate. Insects spend the winter as eggs. Then, why do snakes, turtles and frogs hibernate when it is snowing heavily, while animals such as sparrows, pheasants and squirrels are still foraging all over the country?

This is because there are cold-blooded animals and warm-blooded animals on our planet. Snakes, frogs, turtles and other hibernating animals are cold-blooded animals, also called warm-blooded animals, while sparrows, squirrels and pheasants are warm-blooded animals, also called warm-blooded animals.

The temperature of animals is the same as their name, and their body temperature always changes with the temperature of the external environment. When the temperature is high, their body temperature is high and their metabolic function is strong, so they are more active. After the temperature drops in autumn, their metabolic function gradually weakens and their activities decrease until they no longer go out for food. So when winter comes, they go underground to sleep, and their weight function is very weak. On the contrary, warm-blooded animals have their own constant body temperature. In order to maintain its body temperature, they must feed everywhere in winter to replenish calories.
