Featured Species - Toothless Blindcat (Trogloglanis pattersoni)



The Toothless Blindcat, Trogloglanis pattersoni, is one of two highly cave-adapted eyeless and depigmented catfishes known only from the deepest parts of the Edwards Aquifer under San Antonio, TX. Specimens from its humanly inaccessible habitat have come only from a few very deep city water wells near the area of the aquifer where saline water mixes with fresh water from the Hill Country. Its toothless mouth is apparently adapted for scraping bacterial mats from cavern walls. To learn more, please visit this site.
