Estivation is the prolonged dormancy of an animal during a hot or dry period. Breathing rate, heart rate, and metabolic rate are slowed to conserve energy. Examples include the North American desert tortoise and the California tiger salamander. These animals seek out a cool, shaded places to wait out the heat. Some animals even burrow in mud or seal themselves in a shell with mucus.

SUMMERTIME SLEEPERS by Melissa Stewart is a picture book examining animals that estivate. While children are likely familiar with hibernation, they may not know about estivation. This beautifully illustrated informational book explores a wide range of creatures from around the world who estivate to avoid hot, dry weather. The author uses a short, main line of text along with blocks of detail about each creature’s approach to estivation. Each two-page layout includes a watercolor along with a sketch of the creature. The book concludes with additional information about animals that estivate.
