A completely updated edition, including 122 newly recognized or recently established non-native species of reptiles and amphibians. The new edition of this definitive guide reflects 25 years’ worth of changes in our knowledge of reptiles and amphibians. It includes descriptions of 122 newly recognized or recently established non-native species, updated maps, and new figures and photos. Color illustrations and drawings show key details for accurate identification. More than 100 color photographs and 322 color distribution maps accompany the species descriptions. Clear and concise species accounts provide key characteristics, similar species, habitats, and ranges, as well as subspecies, voice descriptions, and conservation status. This edition will be a crucial resource for professional and amateur herpetologists, naturalists, outdoor enthusiasts, and students.  

Providing accessible information for the professional naturalist and amateur nature-lover alike, this guide highlights the habits and habitats of 60 plants and animals currently listed as endangered or threatened in Kansas and protected by state or federal law.

This profusely illustrated comprehensive key for identifying amphibians and reptiles from the continental United States and Canada incorporates a wealth of scientific findings.Since the first edition was published in 1998 and the second in 2012, the number of currently recognized species of native amphibians and reptiles in the area covered by this key has increased from 545 to 634 to 685, and the number of established non-native species has increased from 39 to 58 to 67. The increase in native taxa reflects the dynamic nature of modern systematics and the use of new (especially molecular) techniques to elucidate relationships and redefine species boundaries. The increase in non-native species reflects the porosity of the North American borders when it comes to controlling animal imports.The key is easy to use and illustrated with outstanding line drawings that show details of color patterns and structures used for identification. To accommodate the additional taxa, the number of line drawings in this third edition has increased from 257 to 279 to 295. In addition, nine maps illustrate the distributions of species that have been recognized since the publication of maps in the most recent editions of the Peterson Field Guides to the reptiles and amphibians of eastern, central, and western North America. A large number of annotations detail current taxonomic ambiguities or disagreements and the literature cited has been expanded. Collectively these features enhance opportunities to teach and learn the classification and identification of amphibians and reptiles in the continental United States and Canada.
