Would you like to carry your house on your back, taking it with you wherever you go? A turtle does. The turtle grows its own shell, which protects against harsh weather and dangerous enemies. A hermit crab is not so polite—it steals another animal’s shell and moves in! Books in this series describe how the homes that different animals build reflect adaptations to their environments, and how animal homes and human homes fulfill similar functions. For grades 2 and up. 24 pages, full-color photographs, paperback. Save $1 per book when ordering 10 or more copies.
