背棘 (總數) : 1; 背的軟條 (總數) : 6 - 7. 16-21 mandibular teeth. Maxillary barbels reaching posterior tip of the humeral process, or occasionally beyond. Mandibular barbels with slender branches. Greyish silver, with dark spots of variable size. Caudal fin occasionally spotted (Ref. 34290).
16-21個下顎齒。 上頜骨觸鬚達到肱骨突起的後頂端, 或者偶然地超過。 顎骨觸鬚有細長的分支。 略灰色的銀色, 有深色的可變大小的斑點。 尾鰭偶然有斑點.(參考文獻 34290)
Occurs in rivers and lakes and prefers deeper water (0-80 m) (Ref. 34291), although it also occurs in shallow water (Ref. 34290). In Lake Victoria it occurs over hard and soft substrates, but is more common over soft bottoms and in water over 13 m deep; feeds on gastropod molluscs and insects (mainly chironomid larvae), and to a minor extent on fishes and ostracoda; able to extract the flesh of snails without crushing their shells (Ref. 12526). Rarely grows to lengths greater than 35 cm SL (Ref. 34290). Oviparous (Ref. 205).
棲息於湖。 最常見深度超過 20 公尺, 在軟質底部之上雖然它也是知道在超過 13 的水在堅硬的底部之上出現公尺深.(參考文獻 34291) 吃軟體動物與昆蟲。 (參考文獻 13624) S. victoriae 是能在沒有打破貝殼的情況下吸取蝸牛的肉.(參考文獻 34291) 很少對長度大於 35 公分 SL 生長。 (參考文獻 34290) 卵生的.(參考文獻 205)
Oviparous (Ref. 205). Distinct pairing during breeding (Ref. 205).非洲: 維多利亞湖流域， Kyoga 湖，維多利亞尼羅河，馬拉噶拉西河。

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00718 - 0.02780), b=2.88 (2.72 - 3.04), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.

營養階層 (Ref.
69278): 3.3 ±0.48 se; based on food items.
Generation time: 4.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
