description Barton Springs Salamander Overview

The Barton Springs Salamander (Eurycea sosorum) is a neotenic aquatic salamander species endemic solely to the four spring outlets that comprise Barton Springs in Austin, Texas. This fully aquatic salamander retains its external gills throughout its life cycle and reaches approximately 6.4 centimeters in length, with a slender body and reduced limbs adapted to its spring habitat. The species was scientifically described in 1993 and listed as federally endangered in 1997 due to its extremely limited range and threats from urban development, water quality degradation, and reduced spring flow in the Edwards Aquifer system that feeds Barton Springs.
