This volume investigates the biological characteristics, distribution, and ecological roles of the amphibian and reptile species native to the British Isles. Malcolm Arthur Smith, a distinguished herpetologist, synthesizes decades of field observations and anatomical research to provide a comprehensive reference for the identification and study of these cold-blooded vertebrates. The text utilizes a systematic approach to catalog species while contextualizing their survival within the specific environmental constraints of the British landscape.

As part of the esteemed New Naturalist series, this work is regarded as a foundational text for both amateur naturalists and professional biologists interested in British herpetology. Its clinical precision and depth of observation establish it as a standard reference for understanding the ecological status of these species within their native range.
