生态学
; 淡水 居于水底的. 熱帶; 22°C - 24°C (Ref. 12468); 11°S - 21°S
Africa: Cunene, Okavango, Buzi, Pungwe (Ref. 52193), Zambezi (Ref. 3203, 52193, 95585), Save (Ref. 13337) and Cubango Rivers (Ref. 3203). Absent from the Kafue River (Ref. 7248, 52193, 95585). Also in Malagarasi River, Lake Rukwa (Ref. 27292), lakes Tanganyika and Malawi (Ref. 3203, 52193). In the Congo basin known from the Lindi-Tshopo (Ref. 106290), upper Kasai (middle Congo River basin)(Ref. 2970), Lualaba (Ref. 45434), upper Lualaba (Ref. 2970, 45434) and the Mweru-Luapula-Bangweulu area (Ref. 13337, 95585).

Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 11.0  range ? - ? cm
Max length : 31.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 4967); 最大体重: 1.1 kg (Ref. 52193)
背棘 (总数) : 0; 背的软条 (总数) : 28 - 37; 臀棘: 0; 臀鳍软条: 23 - 27; 脊椎骨: 39 - 41. Diagnosis: Dorsal fin up to 1.5 times in length of anal fin; origin of dorsal fin in advance of anal fin (Ref. 52193). Snout rounded, in front of mouth; eye well above mouth; chin with fleshy bulge (Ref. 4967). For distinguishing between specimens of Cyphomyrus discorhynchus en C. cubangoensis, the most useful anatomical characters are: longer dorsal fin length, longer anal fin length, higher number of dorsal fin rays and anal fin rays, and a higher caudal peduncle depth and caudal peduncle length ratio in C. discorhynchus than in C. cubangoensis (Ref. 119538).
下巴有肉质的凸起, 吻圆形的, 在嘴之前,眼在相当上面距离嘴.(参考文献 4967) 雄性有臀鳍的边缘凹洼,然而那母鱼是直的。 高的背面, 与背鳍大约三分之一鱼的全长, 用来在津巴布韦与其他的长颌鱼区分.(参考文献 13337)
Nocturnal shoaling species; favors large river channels with a soft bottom and fringing vegetation (Ref. 7248, 52193). Found mainly in sheltered bays, lagoons and swampy areas; occurs also in typical sandy or rocky rivers (Ref. 13337). Feeds on bottom-living invertebrates (Ref. 52193) and insect larvae at night (Ref. 5595). Known to migrate up tributary rivers of Lake Kariba during rainy season, though it is not yet clear whether this is a breeding migration (Ref. 13337). Breeds during summer rainy season; females carry up to 5,000 eggs (Ref. 7248).
夜行的浅滩种; 喜欢大的河道具有一个软质底部与岸边植物。 (参考文献 7248) 主要发现于掩蔽的海湾,泻湖与沼泽的区域了。 在典型的沙或岩石的河中也生存。 (参考文献 13337) 吃昆虫幼生在晚上。 (参考文献 5595) 已知在雨季期间向上洄游到卡里巴湖的支流河, 虽然它是已经不再清澈的是否这是一个繁殖洄游。 (参考文献 13337) 在雨季期间进行繁殖; 母鱼抱卵向上到 5,000个卵。
