Old World Vipers is a comprehensive book that reflects the author's decades of experience with Old World vipers, but also mentions pitvipers as they share many attributes with true vipers in regard to appearance, habits and behaviour.
The true vipers are represented by just over ninety species in fifteen genera, and are essentially old world species being found mainly in Europe, Africa and the Middle East, with just a few species being found in Asia and the Far east. The detailed species accounts illustrate the diversity of Old World Vipers, while providing important information on distribution, taxonomy, behaviour and ecology.
