www.npwrc.usgs.gov — Interest in amphibians continues to rise as people become more aware of this fascinating group of animals. To the uninitiated all frogs may look alike; ditto for salamanders (in the same manner that beginning birders are overwhelmed by the immense variety of small brown birds). One of the purposes of this checklist and online identification guide More...
