背棘 (总数) : 0; 背的软条 (总数) : 9 - 11; 臀棘: 0; 臀鳍软条: 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.
粉红的-白色。 没有眼 (在皮肤下面的退化眼组织). 非常小的腹鳍.(很少地不存在) 大的, 宽的头部。 尾鳍有 4-6个列的乳突; 11-13 分枝了尾部的鳍条。
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.
盲眼与无色的。 虽然没有眼睛它响应光，而且移动远离它 (scotophilia). 栖息于地下的水，否则洞穴在浅滩中那里有坚硬的泥岩底部而且在水池中那里有淤泥-沙子的底部但是用均匀的淤泥-沙子的底部是发现于更时常的洞穴.(参考文献 34868) 有低的繁殖比率而且在鳃腔中孵卵超过 4-5 个月 (参考文献 557; 34868; 27795)。 能存活没有食物由于低的新陈代谢的比率的 2 年。 (参考文献 5326) 顶端掠食者。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6338 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.39 se; based on food items.
Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (K=0.20; low reproductive rate (Refs. 34868;

Fishing Vulnerability (Ref.
