Georgetown Salamander
Eurycea naufragia · also called Georgetown salamanders
In a shaded spring just outside a growing Texas city, a Georgetown salamander drifts through clear groundwater that has fed this exact spot for thousands of years, its entire species now depending on that same water continuing to flow undisturbed as the city above keeps expanding.
Overview
The Georgetown salamander, Eurycea naufragia, is a fully aquatic salamander found only in springs, seeps, and caves in and around Georgetown, Texas. Its extraordinarily narrow range within the Edwards Aquifer system and vulnerability to nearby urban growth make it one of the more conservation-significant amphibians in central Texas.
A species tied to one city’s water table
The Georgetown salamander’s entire existence hinges on groundwater conditions that the very city sharing its name has the power to change, a genuinely direct link between urban development decisions and the survival of an entire species.
Status
Vulnerable, federally threatened — confined to a small number of springs and caves near Georgetown, Texas, threatened by nearby urban and suburban development.
Georgetown Salamander: common questions
Why is the Georgetown salamander considered threatened?
The Georgetown salamander is federally listed as threatened because it survives only within a small number of springs, seeps, and caves near Georgetown, Texas, and ongoing urban and suburban development in the surrounding area threatens to disrupt the groundwater flow and quality the species depends on completely for survival.
Does the Georgetown salamander ever leave the water?
No, a Georgetown salamander retains its gills and remains fully aquatic throughout its entire life, never undergoing metamorphosis into a land-dwelling adult, a lifestyle shared with several other spring and cave-dwelling salamanders in central Texas.
Is the Georgetown salamander related to other Texas spring salamanders?
Yes, the Georgetown salamander belongs to the same broader group of Eurycea salamanders found across the Edwards Aquifer region of central Texas, alongside close relatives such as the Barton Springs salamander and the San Marcos salamander, each restricted to its own narrow set of springs.
Where does the Georgetown salamander live?
The Georgetown salamander is found only in springs, seeps, and caves within a narrow section of the Edwards Aquifer system in and around Georgetown, Texas, making it endemic to this single, small area.
