Frogs and toads are some of the most confusing amphibians to classify. While some of their physical attributes are easy to tell apart, if we take a deeper look at these animals we find it’s not quite that simple. From poisonous skin and bulging eyes to their amazing life cycles, these creatures are as interesting to study as they are difficult to categorize. Once we break down the difference between “true” frogs and “true” toads, it’s easy to see why so many have trouble telling the two creatures apart!

When people go to sleep, bats are just waking up. While young readers may recognize the image of bats in the night skies, where they live may be less familiar. This title takes readers inside bat roosts to uncover the fascinating facts about this creature. Readers will learn the basics of bat roosts—in caves and beyond—and how they help bats survive in the wild. The text also looks at bat’s appearance, behavior, and the crucial role they play in nature’s ecosystems—topics covered in most elementary science curricula. Diagrams, fact boxes, colorful images encourage learning.
