Typhlichthys subterraneus, the southern cavefish, is a species of cavefish in the family Amblyopsidae endemic to karst regions of the eastern United States. [1] T. subterraneus is a one of five obligate troglobitic species in Amblyopsidae.

Southern cavefishes occupy clear, mud-bottomed pools and flowing pools of limestone caves. Extensive field work in the Tennessee Valley indicates that distribution of these cavefishes may be partially limited by poor water quality and an inadequate food base.

4 days ago · The Southern Cavefish is a tiny, ghostly swimmer from deep underground in the southern U.S. With pinkish skin and no eyes, it looks like something from another world. It doesn’t need sight to get around—it relies on other sharp senses to find food. Living in low-light, low-food caves means it’s built for survival.

Southern cavefish inhabit subterranean aquatic (stygobitic) habitats at or near the water table in caves and karst systems within limestone regions. Cavefish can be found in streams and pools with low flow and stable water temperatures between 10-14 ºC (50-57º F).

Southern Cavefish are completely adapted for life in total darkness, lacking eyes, pigment, and pelvic fins, as well as having extensive sensory canals and papillae to detect water movement to navigate, find prey, and avoid predation.

Working with others to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people.

Adults inhabit subterranean water (Ref. 5723). Found in caves which are near the water table and are therefore more uniform than other amblyopsid caves (Ref. 34868). Feed mainly on copepods, amphipods and isopods (Ref. 10294). Eggs are carried in gill chambers of females (Ref. 205). Incubates eggs in gill chamber of females (Ref. 205).
