The Barton Springs Salamander (Eurycea sosorum) is an endangered salamander that only lives in the environs of Barton Springs in Austin, Texas (USA). Barton Springs Salamanders are average sized (adults grow to approximately 2.5 inches in length) and have mottled coloration varying from darkish purple to light yellow.
The species name is an acronym for "Save Our Springs", a group dedicated to preserving Barton Springs, plus a Latin genitive plural ending. Despite inhabiting an urban area, the salamander was not identified until 1993. It was put on the federal List of Threatened and Endangered Species in 1997.
