History
The first intense and continuous scientific study of a cave animal was of a cave salamander, Proteus anguinus. It was originally identified as a "dragon's larva" by Janez Vajkard Valvasor in 1689. Later, the Austrian naturalist Joseph Nicolaus Lorenz described it scientifically in 1768.
Another early scientific description of a cave salamander was performed by Constantine Samuel Rafinesque in 1822 while he was a professor of botany and natural history at Transylvania University in Lexington, Kentucky. The species he described was known to the locals as a "cave puppet" and is now known to be Eurycea lucifuga. His discovery was not surprising at the time because E. lucifuga inhabits near the entrance of caves, thus an in-depth exploration was not required; and, E. lucifuga is neither blind nor depigmented.
