Question: What endangered species was discovered in 1895 during the completion of a well in San Marcos?
Answer: The Texas blind salamander. Its only known habitat is the caverns in the Edwards Aquifer. The troglobitic amphibian is about five inches long, has no eyes, is white in color, and has red external gills. It eats snails, shrimp, and other aquatic invertebrates, hunting its prey by sensing changes in water pressure.
