Pink-white. No eyes (vestigial eye tissues under skin). Extremely small pelvic fins (rarely absent). Large, broad head. Caudal fin with 4-6 rows of papillae; 11-13 branched caudal rays.

Blind and depigmented. Despite the lack of eyes it does respond to light and moves away from it (scotophilia). Inhabits subterranean water or caves which have consolidated mud-rock substrates in shoals and silt-sand substrates in pools but is more often found in caves with uniform silt-sand substrates (Ref. 34868). Has low reproduction rate and broods eggs in gill cavity for up to 4-5 months (Ref. 557; 34868; 27795). Can live for 2 years without food because of low metabolic rate (Ref. 5326). Top predator.
