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.
