Species and their Ecology

» Phylum: Chordata
» Class: Amphibia
» Order: Anura (formerly Salientia): Frogs and toads
» Order: Caudata (formerly Urodela): Salamanders
» Order: Gymnophiona: Caecelians

The U.S. is home to approximately 287 of the world's estimated 6,000 amphibian species. The number of known species changes periodically as new species are discovered and new genetic techniques (e.g. molecular genetics) allow scientists to distinguish among cryptic species.

ARMI conducts research on the natural history of species; writing reports and describing the ecology of America's amphibians. ARMI also collaborates with federal and state partners to design, implement, and evaluate management actions that benefit T&E and other imperiled amphibian species.

Federal and State Partners: Information about the status, management, and conservation of amphibians is found throughout the ARMI web site [e.g. Products Database and Topics Sections]. Please consult the "National Amphibian Atlas" to identify the approximate range of the species of interest.
