This illustrated guide covers the most popular aspects of snake biology. Throughout, colour photographs show the fascinating variety of snake colouration as well as illustrating their amazing capacity for camouflage. The chapters investigate main themes, using text, photography and useful diagrams. There is detailed coverage of snake classification, evolution, natural diversity, size, shape and colouration, physiology, ecology, feeding, defensive behaviour, breeding, mythology, superstition and modern human attitudes to snakes. In addition, there are 'fact boxes' within each chapter, which comprise items of special importance and interest, such as scale-type, population in the wild, egg incubation, etc.
