The volume offers a concise, illustrated survey of animal biology for agricultural and secondary education, beginning with general anatomy and life processes—body plan, skeleton, organs, body cavities and organ systems—and then explaining principles of classification. It proceeds through major animal groups with practical emphasis on those most relevant to farming, notably mammals, birds and insects, while also summarizing worms, molluscs, arthropods and protozoa. Life histories and developmental stages are outlined, common harmful species receive brief mention, and numerous figures support classroom use and selective teaching of topics.
