Clarias cavernicola
An airbreathing cave catfish From Wikipedia, the free encyclopedia
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] 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.[5] Little is known about its reproduction, and attempts to breed it in captivity have failed.[6] 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]
