Demogorgonichthys arcanus, a newly identified eyeless cavefish genus, was discovered in Bobcat Cave beneath the US Army's Redstone Arsenal in Alabama.
University of Alabama scientists said the fish is colorless and faintly electric blue in life, traits linked to species adapted to permanent darkness underground.
The find adds a new US cave-dwelling fish lineage and highlights the unusual biodiversity hidden in subterranean habitats.
