The southern cavefish (Typhlichthys subterraneus) is one of two species of blind cave fishes found in Arkansas. They are found mostly in flowing waters and seem to be attracted to point sources of water resurgence. Southern cavefish tend to rest motionless on the bottom for long periods of time. Estimations of population sizes based on sightings at a single cave yield very low numbers: usually fewer than 150 individuals.
