簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 9-11; 臀棘 0; 臀鰭軟條: 8 - 11; 脊椎骨: 29 - 30. 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.
盲眼與無色的。 雖然沒有眼睛它回應光，而且移動遠離它 (scotophilia). 棲息於地下的水，否則洞穴在淺灘中那裡有堅硬的泥岩底部而且在水池中那裡有淤泥-沙子的底部但是用均勻的淤泥-沙子的底部是發現於更時常的洞穴.(參考文獻 34868) 有低的繁殖比率而且在鰓腔中孵卵超過 4-5 個月 (參考文獻 557; 34868; 27795)。 能存活沒有食物由於低的新陳代謝的比率的 2 年。 (參考文獻 5326) 頂端掠食者。
