"Venomous" Bites from "Non-Venomous" Snakes, Second Edition thoroughly examines the potential hazards associated with bites by non-front-fanged snakes (popularly, but inaccurately, called "rear-fanged snakes"). This diverse group contains approximately 80% of living snake species (approximately 2, 900 species). A large proportion of these snakes were previously assigned to the family Colubridae but, as a consequence of expanding systematics investigations, have been split into multiple families and subfamilies. Many of these snakes produce venoms or oral secretions that contain toxins and other biologically active substances. A large variety of non–front-fanged snakes figure in the pet industry, yet little documented information or formal study of their potential medical importance has been published. Therefore, although the possible medical importance of many of these species has been subjected to speculation since the mid-19th century, there is a limited amount of useful descriptive information regarding the real hazard (or lack thereof) of this wide variety of snakes.

The first edition of this book provided "one-stop shopping" by offering information regarding their possible toxicity and clinical relevance as well as recommendations for medical management of their bites. The second edition expands and updates the content with detailed information about the effects and medical management of bites by a broad representation of non–front-fanged species. The hypothetical venomous nature of some lizards considered as non-venomous such as the Komodo monitor or dragon and their allies, as well as the medical effects of their bites, is also examined. The dynamic taxonomy of advanced snakes is updated, and the bases for some of these fluid changes are discussed. Likewise, terminology is also updated in order to reflect the ongoing debates regarding the definition of "venom" and the balanced reinforcement of nonmedical criteria used to define the biological basis of the term "venomous."

• Fills a gap in toxicological, medical, and herpetological literature by providing a comprehensive review of this entire assemblage of non–front-fanged snakes, with particular attention given to their capacity to cause harm to humans
• Offers a patient-centered, evidence-based approach which is applied to analyzing documented case reports of bites inflicted by a broad representation of species
• Provides expanded and updated detailed information on the clinical management of medically significant bites from non–front-fanged snakes, which is also methodically reviewed, and specific recommendations are provided
• Includes updates of the fluid taxonomy of advanced snakes and also of terminology with particular regard to the definition of "venom" and the nonmedical criteria used to define the biological basis of the "venomous condition" in snakes and lizards
