簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 7; 臀鰭軟條: 19 - 20; 脊椎骨: 45 - 46. Distinguished from other siluriform genera by having the following combination of characters: dorsal and ventral procurrent caudal-fin rays extended rostrally, dorsally reaching a vertical position on dorsal-fin base posterior to dorsal-fin insertion, ventrally continuous with anal fin; caudal fin round; all anal-fin rays unbranched; mouth prognathous, with jaws displaced dorsally on head; adductor mandibulae muscle hypertrophied, covering most of skull and inserting posteriorly onto first neural spine; first pectoral-fin ray soft, not spinous; bright red in life. Differs uniquely from its congeners by the absence of eyes, presence of 25-34 dorsal procurrent caudal fin rays; 14-16 ventral procurrent caudal fin rays; 45-46 vertebrae (Ref. 59347).
與其他的 siluriform 屬藉著具有下列的組合特徵區分了: 背部與腹的前流尾鰭鰭條嘴地延伸,背面在背鰭基底上達到一個垂直的位置在背鰭嵌入後面, 腹地與臀鰭續接在一起; 尾鰭圓; 所有的臀鰭棘條不分枝的; 嘴下巴突出的, 由於顎移置在頭部背面上; 內轉肌下顎肌肉肥大, 包含的大部分的頭蓋骨而且在後部地在第一個髓棘之上插入; 第一個胸鰭鰭條柔軟, 不是刺狀; 鮮紅色活著時。 獨特地不同於它的同類藉由缺少眼, 有 25-34個背部的前流尾鰭鰭條; 14-16個腹的前流尾鰭鰭條; 45-46個脊椎骨.(參考文獻 59347)
Occurs in artificial wells with transparent water, depth range 6 to 12 m and diameter of approximately 1 m (Ref. 59347). The water in the wells is used locally for human consumption. This fish is often mistaken for parasitic leeches " sanguijuelas" due to its bright, blood-red color and vermiform shape. For this reason, this is killed upon incidental capture when extracting drinking water from wells.
出現於人造的以透明的水湧出, 深度範圍 6 到 12 公尺與大約 1 公尺的直徑.(參考文獻 59347) 在井的水地方性地被使用供人類消費。 這一個魚時常被誤認為寄生的水蛭 " sanguijuelas" 由於它的明亮又血紅顏色與蠕蟲狀的形狀。 因為這理由, 當吸取飲用水的時候，這在附帶的抓取之上被殺從湧出。
