Animals eat a variety of foods, from plants and other animals to poop, soil, or blood. This series examines four of the most interesting animal diets and explores the reasons why animals eat those particular foods. This title examines the insects, mammals, and sea creatures that eat blood, the diseases those animals can spread through their eating habits, and the ways doctors have studied and used these animals to advance medicine. This book also includes a table of contents, fun facts, an Animal Spotlight special feature, quiz questions, a glossary, additional resources, and an index. AGES: 7 to 10
