Deep under a US military base, a blind 'demon' creature just surfaced for the first time

Biologists found a pale aquatic creature, the demon cavefish, after three decades. This species remained undetected in Bobcat Cave, beneath Redstone Arsenal. Genetic analysis revealed it lacks vision genes, suggesting deeper aquifer habitats. Protected federal land helped preserve this fragile subterranean ecosystem. The discovery highlights ongoing biological inventories and undiscovered life forms.
