Etymology: uranoscopus:From the Greek "ouranos" (sky) and "skopos" (literally watchman, "skopeoo" means to look at), referring to the supero-lateral position of the eyes (Ref. 43912). More on author: Rüppell.
Environment: milieu / climate zone / 深度上下限 / distribution range 生态学
Africa: Niger (Lake Kainji and further downstream), Cross and Chad basins (Ref. 57127, 81643). Also in the Nile and Lake Turkana system (Ref. 43912, 81643). 非洲: 尼日，十字河，查德。 非洲: 尼羅河， Turkana 系統。
Length at first maturity / 大小 / 重量 / 年龄
成熟度: Lm21.0, range 12 - ? cm Max length : 36.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 57127)
背棘 (总数) : 1; 臀鳍软条: 59 - 73; 脊椎骨: 50 - 57. Diagnosis: 13-16 gill rakers on lower limb of first gill arch; 57-75 branched anal-fin rays; eyes positioned dorso-laterally; adipose fin always absent (Ref. 43912, 57127, 81643). Often with a post-occipital hump, a character also sometimes found in Schilbe intermedius whose head profile is extremely variable (Ref. 57127, 81643). Posterior nostrils closer to each other than are anterior ones; nasal barbel at maximum reaching to midway between eye and opercle, but generally shorter; inner side of pectoral spine feebly serrated (Ref. 43912).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adapted to riverine and lacustrine conditions; appears to live mainly in the open waters; predatory, carnivorous but not strictly piscivorous; young essentially entomophagous (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Especially in the Chad basin of some economic value to the fishermen (Ref. 43912). Maximum reported total length 45 cm (Nile basin)(Ref. 43912).
