Barton Springs salamander
The Barton Springs salamander (''Eurycea sosorum'') is an endangered lungless salamander that only lives in the habitat of Barton Springs in Austin, Texas, USA. Barton Springs salamanders are average-sized (adults grow to approximately in total length) and have mottled coloration varying from darkish purple to light yellow.〔
==Environmental impact==
Amphibian species worldwide have been in decline due to climate change including but not limited to: increased UV radiation, change in precipitation, and various pathogen outbreaks (chytrid fungus which causes Chytridiomycosis〔). However, habitat destruction, degradation, and pollution on a local scale have resulted mainly from land and watershed urbanization. These changes, in turn, affect, among others, water quality and biological community composition of rivers and water systems in the surrounding environment. The wide effects of contamination and degradation on these water systems make analyzing their specific sources difficult since the interactions of factors and overlapping effects may occur. Nonetheless, it is important to study these consequences so that future impact on this and other species may be reduced.
