Following the historical precedent of Peters (1964), a new updated "Dictionary of Herpetology" will provide a comprehensive, single-volume dictionary, with selected cross-referenced entries to clarify the many technical terms and concepts that pertain to herpetology. The Dictionary will provide a complete collection of words that are central to understanding the biology of amphibians and reptiles, offering concise and easy-to-use readable definitions in an A-to-Z format. This reference is essential for students, professionals, breeders, or anyone who is interested in herpetology and its many interdisciplinary connections. The new Dictionary will emphasize terminology related to anatomy, physiology, systematics, evolution, and other disciplines, including newly emerged fields that are relevant to the study of amphibians and reptiles.
