National Audubon Society Field Guide to Reptiles and Amphibians is theĀ first all-photographic field guide contains identification pictures of 657 species, including snakes, toads, frog, turtles, lizards, salamanders and crocodiles, photographed in their natural habitats. Thumb-indexing locates animal type, then arrangement by color or markings; this makes identification quick and easy.
