It is endemic to a small region at the junction of Comal, Bexar and Kendall Counties in Texas.

It is 1.5 to 3.0 in long, with a slender body and external gills, and is an overall translucent pink color.

The salamander depends on a constant supply of clean, cool water from the Edwards Aquifer.

[1] The Comal blind salamander is listed as a threatened species in the state of Texas.

Due to its extremely limited geographic range, its primary threat is contamination of the water sources in the area.
