New Mexico is home to 165 species and subspecies of snakes, lizards, turtles, frogs, toads, and salamanders. Some are ubiquitous and others are localised. If you want basic and reliable information on the lizard in your backyard or the snake you encountered on a hike in the mountains, this handy field guide is invaluable. Both complete and concise, it includes species accounts, maps, photographs, and black-and-white drawings to help you identify the species you have encountered. In addition to basic taxonomy and a glossary, the authors have included suggestions on field protocol and legalities, as well as useful information about the various herpetofauna habitats in the state.
