From Horn Book reviews: "The four main types of reptiles and their physical characteristics are described; double-page entries are amplified by clear color photographs with relevant captions. Diagrams illustrate physiological characteristics in detail, and text boxes highlight especially interesting facts." This book makes answering questions about reptiles fascinating and fun.

What makes an amphibian an amphibian? Do amphibians lay eggs? Most do, but birds and fish lay eggs, too, and they aren't amphibians. Are amphibians animals whose young look totally different from the adults they will become? Yes, but what about butterflies and ladybugs? Their young also change shape as they grow up, but they're not amphibians. So what exactly is an amphibian? Answering that question isn't as easy as it might seem, but What is an Amphibian? makes solving the puzzle fascinating and fun.

What makes an insect an insect? Is it a very small, many-legged creature that flies? That's a good way to describe some insects, but others, such as ants, never take to the air at all. And just how many legs do insects have? A beetle has six legs and spider has eight--are these both insects? Knowing whether or not an animal is an insect can be tricky, but What is an Insect? makes solving the puzzle fascinating and fun.

What makes a fish a fish? How can creatures as different as the great white shark and the tiny minnow both belong to the same class of animals? Why are unusual creatures such as eels and seahorses considered fish, while whales and dolphins are not? Recognizing which aquatic animals are fish can be tricky but What is a Fish? makes solving the puzzle fascinating and fun.
