Anyone can look at a snake and see a creature unique unto itself, a reptile with a set of zoological and biological traits that are entirely its own. Just looking at this distinct animal raises many scientific questions. With regard to evolution, how did such an animal come to be? How does a snake move, and how do its sense organs differ from that of other reptiles? How does it eat, and how does it reproduce? Essentially, how does a snake ""work""? In How Snakes Work: The Structure, Function and Behavior of the World's Snakes, leading zoologist Harvey B. Lillywhite has written the definitive s

Many people have a great fear of snakes. This fear affects their peace of mind, their enjoyment of a holiday in the country, and even their pleasure in their own suburban gardens. It leads to the senseless destruction of one of our valuable natural resources. The morbid fear of snakes can only be dispelled by learning the true facts about these fascinating creatures. This book is addressed to anyone who wishes to learn about the natural history of snakes, or to identify those found in Ontario, but the author speaks particularly to young people, who, unless they have been prejudiced, have a natural interest in all living things. In an easy, conversational manner, the author gives a general account of snakes--what they are, how they travel, their instinct and intelligence, how they feed, their reproduction, hiberation, shedding of the skin, defences usefulness--and discusses popular beliefs and fear of snakes. The separate species are fully described in a simple, non-technical and readable style. The author is also an artist, and the book is illustrated with his own wash drawings and line sketches. There are two beautiful colour plates. Distribution maps show the range of species. For those wishing to pursue the study of snakes more fully, an appendix provides a list of snakes with scientific names, a key for the identification of the snakes, directions for determining their sex, directions for collection and preserving, directions for determining their sex, directions for keeping snakes as pets, diagrams giving anatomical names of parts of snakes, a glossary, and a concise and up-to-date outline of rattlesnake bite and first aid treatment.

"This book is the first and only comprehensive guide to the snakes of Central and Western Africa. In North America, field guides are taken for granted, but for much of the world these guides don't exist. In many high biodiversity areas of the third world, even the specialist is stumped by many specimens. Jean-Philippe Chippaux and Kate Jackson have a combined half-century of experience studying these snakes in the field. Covering identification, evolution, behavior, and occurrence, Snakes of Central and Western Africa also features maps, photos, and drawings for each species to aid in identification. Each year 20,000 people die from snake bites in Africa, and this problem can only worsen with the increasing human presence in these habitats. While poverty, transportation, and the availability of medical care are all problems that must be addressed, a sound knowledge of the species is the necessary first step. An essential read, which, ultimately, can save lives"--
