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.

From a review by Horn Book: "The physical characteristics of insects are described in a simple, straightforward, explanatory text, illustrated by large color photographs. Drawings are used to diagram anatomical features and to show details, such as how insects walk with six legs."

Defines amphibians and describes their lives, including their maturation, mating, sense perception, and feeding.

From Horn Book reviews: "Large full-color photographs illustrate a simple, straightforward, explanatory text describing the physical characteristics of birds. Close-up drawings are also used to diagram such anatomical features as the tiny hooks that hold a bird''s outer feathers together." A glossary extends the information found in the text.
