articleResearchers have uncovered a new species of blind cavefish hiding in one of the most studied cave systems in Alabama , leading scientists to reshape their understanding of evolution, biodiversity and conservation. The newly discovered Demon cavefish (Demogorgonichthys arcanus) is completely eyeless, colorless and is electric blue. Researchers found that the Demon cavefish and the Southern cavefish occupy the same pools inside Bobcat Cave , yet they are not closely related. Researchers say that the Demon Cavefish escaped detection because it closely resembles another blind species already known from the cave. "The Demon cavefish is a reminder that our inventories are far from finished, even in well-explored places," Niemiller said.
