The Barton Springs salamander is a small, aquatic salamander native to the springs of the Edwards Aquifer in Texas. It is a critically endangered species, primarily found in the waters of Barton Springs, a popular swimming area in Zilker Park. This salamander is known for its slender body, which can reach lengths of up to 3 inches, and its unique gills that allow it to breathe underwater. These salamanders rely on clean, cool water and are sensitive to changes in their environment. Their habitat is threatened by urban development, pollution, and changes in water flow. Conservation efforts are in place to protect the Barton Springs salamander and its natural habitat, ensuring its survival for future generations.
