What animals hibernate in winter?

There are many animals that hibernate in winter, such as snakes, frogs, turtles, squirrels, wasps, hedgehogs, earthworms, snails, bats, Dormice and so on. Different animals hibernate in different ways.

Among them, frogs will start to hibernate in soil or caves in late autumn. The reason is that the frog's body temperature will be affected by the cold winter temperature. In order not to freeze to death, they hibernate and keep a certain temperature for the winter. It will revive in the spring of the following year and then breed in the water.

Squirrels, on the other hand, will store a certain amount of grain before winter comes, then seal the hole with hay when winter comes, and spend the winter with their furry tails and stored grain.
