Blind Salamander Pale Ale is the first of a series of Rahr beers called Rare Breed. These beers are dedicated to improving the lot of endangered Texas species. Rahr is making donations from these proceeds to the Texas Parks & Wildlife Foundation to help with the recovery of these species.

The Texas Blind Salamander is a rare cave-dwelling troglobite amphibian native to San Marcos, specifically the San Marcos Pool in the Edwards Aquifer. It has bright red external gills for absorbing oxygen from the water. Its mature length is 5 cm and its diet varies by what flows into its cave, including shrimp, snails and amphipods.
