The cave catfish[2] (Clarias cavernicola)[3] is a critically endangered species of airbreathing catfish.[1] This cavefish is only known to live in the Aigamas cave, Otjozondjupa region, Namibia.[4][2] It has also been reported from the nearby Dragon's Breath Cave.[5] The golden cave catfish lack pigmentation and are up to 16.1 cm (6.3 in) in standard length.[2] They have very small eyes that are covered with skin, and are probably effectively blind.[2] 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.[7] The population is threatened by chance events and water extraction from the cave lake, which has resulted in a drop of the water level.[1]
It is the only known cavefish in mainland Southern Africa.[8]
