A concise natural-history survey of European snakes that opens with general anatomy and classification, then examines skin, coloration, skeleton, dentition, venom systems, senses, internal organs, reproduction, behavior, parasites, distribution, and interactions with humans. The bulk provides a systematic species-by-species account with diagnostic descriptions, ranges, and illustrations, accompanied by plates and figures. Practical remarks on habits, life histories, and specimen sources support identification. Emphasis is on morphological characters and clear descriptions rather than exhaustive bibliographies, with contributions summarizing parasite records and regional collections.
