The Edwards Aquifer is the primary source of drinking water for 1.7 million people in the region. It is also the habitat for a unique system of aquatic life. Highly specialized, unique species, such as the widemouth blindcat, the toothless blindcat, and blind shrimp are found underground in the Edwards Aquifer. The U.S. Fish & Wildlife Service (USFWS) has designated eight species that live in the Edwards Aquifer, the San Marcos Springs, and the Comal Springs aquatic ecosystems as either threatened or endangered. Species are listed as threatened or endangered based on declining numbers or the loss (or potential loss) of their critical habitat.
