“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.

Venomous Bites from “Non-Venomous” Snakes 1st Table of contents:

Chapter 1. A summary of taxing taxonomic considerations: non-front-fanged snakes and the shifting sands of systematics
1.1. The shifting sands of taxonomic reassignments and their relevance to the envenomed patient

1.4. General phylogenetic inventory of Caenophidian snakes: comments and consideration of known medical significance
Chapter 2. Differences between buccal gland secretion and associated venom delivery systems of front-fanged snakes and non-front-fanged snakes: Low- versus high-pressure gland function and canaliculated versus solid dentition
2.1. Basic considerations regarding gland structure and function
2.2. Overview of hypotheses for the evolution of venom-delivery systems and other adaptive gland functions
2.3. Theories considering the evolution of canaliculated fangs and enlarged grooved teeth
