This volume investigates the identification and classification of diverse mammalian species through a structured, visual-heavy framework. The authors, Peter Schouten and Ronald Strahan, utilize their expertise in biological illustration and zoological research to provide a systematic guide for identifying mammals. The text serves as a diagnostic tool, organizing species by physical characteristics and behavioral traits to assist readers in field identification.

The subject matter points to a specialized, highly visual reference text intended for naturalists and students of zoology. The framing suggests a focus on practical identification methods that prioritize clear, descriptive data over theoretical discourse.
