Why Do Animals Hibernate?

Hibernation is a fascinating animal adaptation. While the behavior is commonly recognized, many don't know exactly what's happening in the animal's body to cause hibernation. In the colorful pages of this accessible volume, budding zoologists will discover much about the science of hibernation and which animals undergo it, through at-level text. They'll also find out how the animals prepare for the long rest and what happens to them after hibernation. The main concepts-supportive of the elementary science curriculum-are reinforced by carefully chosen images of animals in the wild.
