An illuminating introduction provides the reader with evolutionary and characteristic information about reptiles and amphibians. The individual entries that follow describe over 200 species -- their physical characteristics, geographical distribution, morphology -- and offer visual symbols for their habitat as well as whether they are poisonous, diurnal or nocturnal. A detailed glossary and index are also included. "Simon & Schuster's Guide to Reptiles and Amphibians of the World" is a spectacular and authoritative reference to these curious and intriguing animals.
