How did reptiles and amphibians evolve? Where did they originate? What function does their skin serve? What is their third eye and what does it do? From frogs, snakes and lizards to turtles and iguanas, this colourful handbook reveals the fascinating world of these incredibly diverse species. Informative discussions on the anatomy, evolution, behaviour and habitats of reptilian and amphibian families will provide you with a wealth of knowledge and entertain at the same time. From the miracle of metamorphosis to homing and migration; from defence and communication to movement and temperature regulation, this handbook explains everything there is to know in a concise and readable manner. The practical aspects of studying and caring for these animals are covered too, making the book both a comprehensive guide and a joy to read. With special sidebars and double-page features throughout, and an extensive glossary and appendix of sources for clubs, societies and organisations, 'Reptiles and Amphibians' is essential reading for anyone interested in the natural world.
