The golden cave catfish (Clarias cavernicola)[2] is a critically endangered species of airbreathing catfish.[3] This cavefish is only known to live in the Aigamas cave, Otjozondjupa region, Namibia.[4][5] They lack pigmentation and are up to 16.1 cm (6.3 inches) in standard length.[5] They have very small eyes that are covered with skin, and are probably effectively blind.[5] They feed on detritus and invertebrates that fall into the lake in which they live. The population is estimated at 200–400 individuals.[6] Little is known about its reproduction, and attempts to breed it in captivity have failed.[citation needed] The population is threatened by chance events and water extraction from the cave lake, which has resulted in a drop of the water level.[3]

It is the only known cavefish in mainland Southern Africa.[7]
