简单描述

背的软条 (总数) : 9 - 11; 臀鳍软条: 9 - 11; 脊椎骨: 33 - 35. Scales minute and embedded. Pelvic fins absent. Branched caudal fin rays 11-17; branchiostegal rays 6. Triads of sensory papillae occur midlaterally and scattered clusters of neuromasts are present on the head. Coloration uniform dark gray to back with paler venter.
鳞片细小与深入的。 腹鳍不存在。 分枝的尾鳍鳍条 11-17; 鳃条骨 6. 知觉乳突的三个一组侧面中央地出现，而且神经瘤的分散群在头部上出现。 颜色均匀的深灰色背面有较灰白的腹部。
Adults occur in springs and caves (but almost always near surface). They live underground but emerge above ground in springs (Ref. 5723). Active in springs at night and usually retreat underground during the day. The few individuals which venture into the spring portions of their habitat may show strong rheotaxis for half to one-minute periods but usually show strong thigmotaxis and hide under rocks or debris (Ref. 34868). Feed at night on amphipods, midge larvae, tiny worms and micro-crustaceans. Fecundity averages about 100 eggs per female (Ref. 10294). Eggs are carried in gill chambers of females (Ref. 205).
出现于泉水与洞穴。 (但是几乎总是近表面的) 住在地下但是浮现地面上在泉水中.(参考文献 5723) 活跃的在泉水中在晚上而且通常撤退到地下在白天期间。 冒险进入的少数个体他们的栖息地的泉水地带为半分钟到一分钟可能显示强的逆流性时期但是通常显示强的趋触性而且躲藏在岩石或残砾下.(参考文献 34868) 晚上捕食片脚类动物，蚊仔鱼，极小的蠕虫与细小的甲壳动物。 孕卵数平均大约 100个每母鱼卵。 (参考文献 10294)
