Texas blind salamander

Found only in the subterranean water systems of Edwards Plateau in Texas, this troglobite salamander is another underworld amphibian that could easily be mistaken for a baby dragon.

Measuring at just under half a foot in length, these creatures were first collected in 1895 from a well that drew water from 58 meters below the surface. Like most troglobites, they have lost their sense of sight, an adaptation to their dark habitat.
