Warm-Blooded or Cold-Blooded?

Although these terms are used to describe various types of animals, neither term is actually accurate. This book makes a complicated subject easy to understand. Through captivating photographs, Bobbie Kalman shows how some animals regulate their body temperatures in different ways, such as by shivering or panting, flapping their wings, or swimming in different parts of oceans. Topics include how each type of animal is suited to its environment, how some animals use behavior to control their body temperatures, and how animals avoid overheating or heat loss.
