With nearly 6,000 species currently identified, frogs and toads are the most familiar and abundant amphibians on the planet. They were the first vertebrates to make a sound, quickly making themselves known by croaking or calling, and they can now be found in most parts of the world. Frogs and Toads is a comprehensive guide to the natural history of these popular and charismatic creatures. Since the first frogs appeared 220 million years ago, they have evolved into 47 unique families. The book describes their remarkable diversity in shape, colour and markings, and their unique anatomy and development, from tiny tadpole to fully grown frog. It explains where frogs and toads live and what they eat, and reveals the physiological and behavioural tricks they use to survive and often thrive, such as the crucial use of camouflage and toxic secretions. The book also explores frogs' interaction with humans, from scientific research and the trade in exotic pets, to how their survival is threatened by habitat destruction, climate change and disease. Drawing on the latest research and the recently revised classification system, and illustrated with eye-catching colour photographs throughout, this guide will appeal to amateur naturalists and all those with an interest in the world of frogs and toads. It is fully checked and approved by a Museum scientist and includes a comprehensive listing of all frog families currently recognised.
