Young readers will find everything from the breeding and training of horses to the mating songs of frogs in these comprehensive, informative books about a wide variety of animals. Each engrossing volume examines the habitat, range, classification, evolution, anatomy, behavior, species identification and endangered status of its subject. Brilliant photography captures animals and underscores the great variety of species found within each family or order. Distribution maps pinpoint where each animal is located, and a time line traces its evolution. Also included are detailed studies -- and stunning illustrations -- of the animals' anatomy, their amazing adaptations and survival skills and the obstacles they face today, due in large part to humans.
