背棘 (总数) : 0; 背的软条 (总数) : 55 - 75; 臀棘: 0; 臀鳍软条: 17 - 22. Diagnosis: snout long, about equal to the post-ocular length of the head (Ref. 28714), produced into a stout trunk whose thickness and angle to the face are variable (Ref. 34290). Dorsal fin very long, more than twice the anal fin length, with less than 75 rays, its origin above or slightly in front of the insertion of the pelvic fins (Ref. 4903, 28714).
头部背面轮廓笔直地或略微弯曲了, 非常倾斜的。 吻伸展到了一个矮胖的躯干 , 厚度与角到面是可变的。 唇厚的。 眼小的。 暗青铜色的背面, 腹部颜色较淡.(参考文献 34290)
Solitary, nocturnal species (Ref. 28714). In Lake Victoria in both coastal and offshore waters (Ref. 4903). May spawn in the main lake, perhaps in deep water over rocks (Ref. 52083). In Lake Kyoga in open water rather than weedy areas (Ref. 55624). Bottom feeder; small fishes eat lithophilic insects; adults almost exclusively insectivorous; chironomids dominate in the diet (Ref. 12526). Oviparous (Ref. 205).
独居性又夜行的种。 捕食底栖的动物, 与宝刀鱼仔鱼作为一个主要的食物.(参考文献 28714) 卵生的.(参考文献 205)
