The variety of animal species is staggering. So, too, is the diversity of form, behaviour and adaptation that animals display. Even in seemingly inhospitable areas, such as arid deserts and frozen polar regions, animals have evolved characteristics that enable them to survive and thrive. This lavishly illustrated visual reference book is an authoritative survey of the intriguing world of animals. The first section is an overview of animal evolution, classification, biology, behaviour, habitats and adaptations. Special attention is paid to current conservation issues. At the core of the book is an encyclopedic survey of all the animals groups - mammals, birds, reptiles, amphibians, fishes and invertebrates. A gallery of more than 2,000 species illustrations conveys the variety and wonder of the animal kingdom. These are supported by hundreds of detailed explanatory diagrams, distribution maps and colour photogrpahs. Vulnerable and endangered species are clearly marked, and many are discussed in detail. With its rich visual content, stunning graphics and informative text, The Encyclopedia of Animals is the ideal reference guide to the animal kingdom.
