Summary:
- Researchers have identified a new species of troglobitic (cave-dwelling) fish, *Speoplatyrhinus poulsoni* (or a closely related new species), inhabiting the subterranean limestone aquifers beneath a military base in Alabama.
- The discovery highlights the unique evolutionary adaptations of cavefish, such as the loss of pigmentation and vision, and emphasizes the critical importance of preserving fragile groundwater ecosystems that remain largely unexplored by the scientific community.
