背棘 (总数) : 1; 背的软条 (总数) : 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个下颚齿。上颌骨触须达到肱骨突起的后顶端, 或者偶然地超过。颚骨触须有细长的分支。略灰色的银色, 有深色的可变大小的斑点。尾鳍偶然有斑点.(参考文献 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).

栖息于湖。最常见深度超过 20 公尺, 在软质底部之上虽然它也是知道在超过 13 的水在坚硬的底部之上出现公尺深.(参考文献 34291) 吃软件动物与昆虫。 (参考文献 13624) S. victoriae 是能在没有打破贝壳的情况下吸取蜗牛的肉.(参考文献 34291) 很少对长度大于 35 公分 SL 生长。 (参考文献 34290) 卵生的.(参考文献 205)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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. 93245).

营养阶层 (Ref. 69278): 3.3 ±0.48 se; based on food items.

回复力 (Ref. 120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Fec = 1,500).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).
