Hibernation cycle zzzz




HIBERNATION

Hibernation is a way that some animals deal with the harshness of winter. They curl up in a safe place and stay there until winter ends. Hibernating animals seem almost dead. They barely breathe, and their body temperature is near the freezing mark. In warmer weather they return to their regular activities.

Animals that hibernate are called hibernators. They include bats, hedgehogs, ground squirrels, groundhogs, and marmots.
