The only known specimen of Eurycea robusta measured 10 cm (4 in) total length.
Eurycea robusta is restricted to Texas.
Because Eurycea robusta was only seen once while drilling in a streambed, it is guessed that this salamander species inhabits subterranean streams.
The Blanco Blind Salamander is listed as a threatened species by the Texas Parks and Wildlife Department and is fully protected by the state.
Eurycea robusta has been found only in the Balcones Aquifer near the Blanco River in Hays County, Texas.
