2. In autumn, the little squirrel began to prepare for the winter. It climbed to the top of the pine tree, stretched out its small hand to pick up the pine cones, and then put them in its arms one by one and transported them back to its small tree hole in winter storage.
It's autumn, and the little snake slowly crawls into the tree hole to see if there is enough food. Seeing that the once slow food has been reduced by half, there is no way but to slowly climb out of the cave to find food.
Mountain rat has been hibernating for half a year. When winter comes, they dig tunnels, get into caves and curl up. Their breathing gradually slowed down and almost stopped. Like death, their pulse correspondingly became extremely weak, and their body temperature plummeted to 5℃.
The crocodile built himself a hibernating nest near the water on the shore, climbed into the hole as soon as it was cold, and slept for a whole winter.
6. Snakes hibernate in groups, often in groups of hundreds. They are interwoven to keep warm and raise body temperature. If you spend the winter alone, you may freeze to death. Snakes, like frogs, are warm animals, and spending the winter together can reduce the mortality rate.
