Blanco Blind Salamander

Range

It is extremely rare and can only be found in one locality in San Marcos, Hays County, Texas. The species was first discovered during a spring excavation in the Blanco River. Its range is restricted to the Balcones Aquifer in the vicinity of the Blanco River.

Habitats

Underwater aquatic habitats; water-filled caves and subterranean water sources that maintain clean, cool water. They may feed on snails, shrimps, and amphipods. Not much is known of their reproductive methods. However, based on knowledge of the E. rathbuni, females mature and reproduce throughout the year as is typical of many cave-dwelling species.

Identification

The salamander is aquatic, blind, cave-dwelling and one of the species of lungless salamanders. Lacking pigment and seemingly colorless, it is gilled and has a pair of reduced eyes. The average length for this salamander is 4 inches. It has relatively robust limbs, a stalwart body, a thick tail and a reasonably tall tail fin of about 2 inches.
