Why Do Thorny Devils Have Two Heads?: And Other Curious Reptile Adaptations

There’s a good reason why the thorny devil has a false head on its shoulders. It’s an adaptation that developed to help protect the thorny devil when the reptile feels threatened. Most adaptations have a good explanation–but that doesn’t make some of them any less odd! From snakes shedding their skin a few times a year to the almost unbreakable shells of reptile eggs, reptile adaptations are made even more fascinating in this book through full-color, up-close photographs. In addition to cool adaptations, readers learn science curriculum topics such as the main features of reptiles, evolution, and life cycles.
