Overview

Snake expert Carl Ernst and co-author Evelyn Ernst reveal the unusual lifestyles of these fascinating creatures, describing every known aspect of each of the 131 species found in the United States and Canada. From the venomous rattlers to the docile garter snakes, each species is shown to display a unique set of behaviours and adaptations to its environment. More than simply a field guide, this reference begins with an introduction to snake biology and evolution, which is followed by an identification guide and key to the North American species. The heart of the book is the species accounts which, accompanied by colour photographs, provide detailed information on identifying features, geographic variation, known fossils, current distribution, habitat type, behaviour, reproduction, growth, diet and predators. Completing the book is a glossary of terms and a comprehensive reference section.
