Amphibians represent an ancient group of cold-blooded animals, the first species of which appeared on Earth hundreds of millions of years ago. A detailed atlas contains species found in the Western Palearctic region. Each profile provides a detailed description, behavior and interesting information about the lifestyle and life cycle. Color maps show the distribution of individual species, and unique photographs show the details essential for identification. The author, Christophe Dufresnes, a renowned French herpetologist and researcher, received his doctorate from the Université de Lausanne and collected a wealth of visual material during his travels in Europe, which he used in this publication.
