Reptiles and amphibians are both cold-blooded vertebrates. This fun book introduces readers to a mix of both animal types. They'll learn how amphibians transform their gills into lungs through metamorphosis and discover salamanders, the only vertebrates that can regrow a lost leg or tail. Along with fun facts, students will read about snakes that can swallow their prey whole, turtles that hibernate by burying themselves in mud, and color-changing chameleons. Supplemented with colorful photographs, this age-appropriate book provides a comprehensive overview of reptiles and amphibians and their defining characteristics.
