生態學
; 淡水 居於水底的. 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).
非洲: 剛果河流域上游，坦噶尼喀湖與馬拉威，尚比西河與庫邦河.(參考文獻 3203) 也發現於庫內內河，奧塔萬戈河， Buzi 與 Pungwe 河。 在班韋烏盧湖，湖 Mweru 與救援河也生存。 (參考文獻 13337) Kafue 河沒有出現。 (參考文獻 7248)
Length at first maturity / 大小 / 重量 / 年齡
成熟度: Lm 11.0 range ? - ? cm
Max length : 31.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 4967); 最大體重: 1.1 kg (Ref. 52193)
背棘 (總數) : 0; 背的軟條 (總數) : 28 - 37; 臀棘: 0; 臀鰭軟條: 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).
Body shape (shape guide): fusiform / normal; Cross section: oval.
下巴有肉質的凸起, 吻圓形的, 在嘴之前，眼在相當上面距離嘴.(參考文獻 4967) 雄性有臀鰭的邊緣凹窪,然而那母魚是直的。 高的背面, 與背鰭大約三分之一魚的全長, 用來在辛巴威與其他的長頜魚區分.(參考文獻 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).
夜行的淺灘種; 喜歡大的河道具有一個軟質底部與岸邊植物。 (參考文獻 7248) 主要發現於掩蔽的海灣，潟湖與沼澤的區域了。 在典型的沙或岩石的河中也生存。 (參考文獻 13337) 吃昆蟲幼生在晚上。 (參考文獻 5595) 已知在雨季期間向上洄游到卡裡巴湖的支流河, 雖然它是已經不再清澈的是否這是一個繁殖洄游。 (參考文獻 13337) 在雨季期間進行繁殖; 母魚抱卵向上到 5,000個卵。
