This comprehensive key for identifying specimens of amphibians and reptiles in the U.S. and Canada - the first since 1983 - incorporates the wealth of scientific findings generated by molecular systematics (the study of DNA to determine genetic relationships) and simplifies identification by making geographic origin a leading factor.
This book provides an extensive key to amphibians and reptiles in North America. If you are studying herpetology, this book has many diagrams in it that really help with keying out dinstinguishing characteristics. Plus, the book is set up simply in plain English. Other keys that I have used were not as extensive as this one, and they were usually confusing. This key takes away all the ambiguity.
Excellent for serious biologists

This breaks down characters for families very easily. The only draw back to this book is that it doesn't contain common names, but that can always be looked up. I recommend this book to any biologist or herpetologist. It also shows what the basic characters are with pictures.
An excellent dichotomous key for herpetofauna.
