Reptiles and Amphibians Explained [PDF ebook] 

While reptiles and amphibians are distantly related, these cold-blooded creatures are still distinctively different. Amphibians spend the first part of their lives in the water, then slowly migrate to solid ground. Reptiles hatch from eggs on land. Readers will learn about the similarities and differences between these two groups and test their knowledge to distinguish between the two.
