簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 9 - 11; 臀鰭軟條: 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.
Body shape (shape guide): elongated.
鱗片細小與深入的。 腹鰭不存在。 分枝的尾鰭鰭條 11-17; 鰓條骨 6. 知覺乳突的三個一組側面中央地出現，而且神經瘤的分散群在頭部上出現。 顏色均勻的深灰色背面有較灰白的腹部。
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).
出現於泉水與洞穴。 (但是幾乎總是近表面的) 住在地下但是浮現地面上在泉水中.(參考文獻 5723) 活躍的在泉水中在晚上而且通常撤退到地下在白天期間。 冒險進入的少數個體他們的棲息地的泉水地帶為半分鐘到一分鐘可能顯示強的逆流性時期但是通常顯示強的趨觸性而且躲藏在岩石或殘礫下.(參考文獻 34868) 晚上捕食片腳類動物，蚊仔魚，極小的蠕蟲與細小的甲殼動物。 孕卵數平均大約 100個每母魚卵。 (參考文獻 10294)
