# New eyeless 'demon cavefish' species discovered in Alabama named after mythical Demogorgon This genetically unique species could be one of the rarest fish in the world. - **Source:** [Popular Science](https://brifing.si/source/cc3d313a-759c-4802-b881-fc8585f35ef9) - **Published:** 2026-07-21 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/a822cd3c-6f44-44f9-89af-853b4317aee5 ## Mysterious Cave Ecosystem Bobcat Cave in Alabama hosts a unique underground world with rare species. This 1,490-foot limestone network is accessible only through narrow, water-filled tunnels. Scientists have been studying the endangered Alabama cave shrimp here for 40 years. ## Surprise Discovery Auburn University researchers recently found an unexpected neighbor in the cave: a pale, eyeless fish measuring 2 inches. Genetic analysis confirmed it as a completely new species to science, distinct enough to warrant its own genus. ## Mythological Naming The new species was named 'Demon Cavefish' (Demogorgonichthys arcanus). The name draws not from Stranger Things but from the ancient Greek underworld deity Demogorgon. 'Arcanus' means 'hidden' in Latin, fitting for this elusive creature. ## Genetic Uniqueness The fish lacks part of the rhodopsin gene linked to light sensitivity, setting it apart from other cavefish. Researchers are amazed it remained undiscovered for so long in such a well-studied cave system. ## Conservation Concerns Only about 20 individuals have been observed so far. Experts speculate it may have recently migrated from deeper aquifers or existed unnoticed. Like the Alabama cave shrimp, it highlights the need for conservation in these fragile ecosystems. ## Scientific Significance The discovery underscores how little we understand cave ecosystems. Biologists emphasize this new species as a wake-up call for protection. Demon Cavefish also offers unique opportunities for evolutionary biology and genetic research. ## Sources covering this story - https://www.popsci.com/environment/demon-cavefish-alabama-demogorgon/ — --- _Summary written by Brifing from the original reporting.
