The first—and only—authoritative guide to the snakes of Central and Western Africa. Nobody knows exactly how many snake species live in the biodiversity hotspots of Western and Central Africa. While field guides abound that make mammals, birds, and even insects identifiable for residents, travelers, and scientists, half a continent's herpetological richness has remained shrouded in mystery. In a region where nearly 30,000 people die from snake bites every year, even dire medical necessity has been an insufficient inducement for researchers to take on the daunting task of assembling an authoritative list of extant species, let alone a full descriptive record to aid in identification, the essential first step to administering an effective antivenin. The reptiles of Central Africa, particularly, are the most poorly studied in the world, despite their crucial role in the survival of threatened ecosystems. With Snakes of Central and Western Africa, Jean-Philippe Chippaux and Kate Jackson have created a game changer. The result of years of field research and systematic study in the world's leading museums, this book compiles for the first time a comprehensive guide to the region's snakes. Covering a vast swath of the continent, ranging from Mauritania in the northwest to Rwanda in the east and Angola in the south, Chippaux and Jackson provide detailed accounts for the more than 200 species of snakes that inhabit the region. The first part of the book is devoted to the taxonomic characters used for identifying snakes. The authors deal with the evolution and biogeography of African snakes as well as epidemiological and clinical aspects of snakebite. The remaining chapters are organized phylogenetically, following the latest consensus on evolutionary patterns of major snake lineages in sub-Saharan Africa. Species identification is facilitated by simple and accessible dichotomous keys and detailed descriptions of morphological characteristics, complemented by numerous drawings, photos, and distribution maps. Invaluable information on taxonomy and natural history is also included. The book concludes with a comprehensive index and a list of nearly 600 references. Snakes of Central and Western Africa illuminates a previously little-known part of the natural world, provides vital information that could save many lives, and will make an excellent addition to any herpetology library.

The past decade has been a period of explosion of knowledge on the chemistry and pharmacology of snake toxins. Thanks to the development of protein chemistry, nearly a hundred snake toxins have been purified and sequenced, representing one of the largest families of sequenced proteins. Moreover, the mode of action of these toxins has been largely elucidated by the concerted efforts of pharmacologists, electro physiologists, and biochemists. As a result of these studies, some of the snake toxins, e.g., a-bungarotoxin and cobra neurotoxins, have been extensively used as specific markers in the study of the acetylcholine receptors. Indeed, without the discovery of these snake toxins, our knowledge of the structure and function of nicotinic acetylcholine receptors would not have advanced so rapidly. The contribution of snake venom research to the biomedical sciences is not limited to the study of cholinergic receptors. Being one of the most concentrated enzyme sources in nature, snake venoms are also valuable tools in biochemical research. Venom phosphodiesterase, for example, has been widely used for structural studies of nucleic acids; proteinase, for the sequence studies of proteins and pep tides ; phospholipase A , for lipid research; and L-amino acid oxidase for identifying optical z isomers of amino acids. Furthermore, snake venoms have proven to be useful agents for clarifying some basic concepts on blood coagulation and some venom enzymes, e.g., thrombin-like enzymes and pro coagulants have been used as therapeutic agents.

This book is the first significant contribution to thoroughly examine the potential hazards associated with snakes of the former family, Colubridae. This family contained >65% of living snake species (approximately 3,000 taxa) and has recently been split into multiple families. Many of these snakes produce oral secretions that contain toxins and other biologically-active substances. A large variety of these 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-nineteenth century, there is a limited amount of useful descriptive information regarding the real hazard (or lack thereof) of snakes belonging to this diverse, artificial family. There is a need for "one-stop shopping" offering information regarding their possible toxicity and clinical relevance as well as recommendations for medical management of their bites. This book is the first synthesis of this information and includes evidence-based risk assessment, hazard rankings and specific recommendations regarding important species, many common in captivity. Fills a gap in the toxinological, medical and herpetological literature by providing a comprehensive review of this entire assemblage of snakes, with particular attention given to their capacity, real or rumored, to cause harm to humans A patient-centered, evidence-based approach is applied to analyzing documented case reports of bites inflicted by approximately 100 species. Clinical management of medically significant bites from non-front-fanged colubroids is methodically reviewed, and specific recommendations are provided
