背棘 (总数) : 0; 背的软条 (总数) : 65 - 82; 臀棘: 0; 臀鳍软条: 52 - 63; 脊椎骨: 53 - 54. Diagnosis: head oval-shaped in dorsal outline (Ref. 248), fairly broad (width 15.9-21.1% SL) and rather long (24.1-27.6% SL)(Ref. 57129, 81644). Snout rounded (Ref. 248). Tooth plates small (Ref. 248). Width of premaxillary tooth plate 22.3-27.5% HL (m=24.9), of vomerine plate 19.9-24.5% HL; interorbital space relatively narrow (40.6-46.1% HL, averaging 42.8% HL) (Ref. 57129, 81644). Barbels relatively short, but longer than head (Ref. 57129). Frontal fontanelle usually short and wide/squat ('sole-shaped')(Ref. 248, 57129). Occipital fontanelle small and oval-shaped; supraorbital and 'dermosphenotic' bones become sutured (Ref. 248). Pectoral spine robust and slightly curved (Ref. 248), with serrations on anterior and posterior margin (Ref. 57129, 81644). Gill rakers long and distantly set; suprabranchial organ well developed; openings of the secondary canals of the lateral line appear as irregular white spots on the body (Ref. 248). 15-24 gill rakers on first gill arch; 52-63 anal fin rays (Ref. 81644). Coloration: characteristic for its very light colouration; back and sides yellowish brown, belly clear/light grey (Ref. 57129, 81644).
淡又淡黄色的颜色促进鉴定。头部椭圆形的在背部的轮廓中; 吻圆的。额骨囱门通常短与蹲着的;(唯一的-形状的') 后头骨囱门小而椭圆形的。那眶上的与那皮蝶骨的' 硬骨变成缝合。齿板小的。胸棘结实的而且些微地弯曲。鳃耙长的而且远远地竖立。鳃前的器官发展良好的。侧线的第二感觉管的开口在身体上呈现不规则的白色斑点。

Facultative air-breathing (Ref. 126274); Found more abundant in forest floodplain ponds, grassland floodplain ponds and marshes than in rivers (Ref. 31579). Maximum reported size 235 mm TL for West Africa (Ref. 57129) and Lower Guinea (Ref. 81644).

发现更丰富的在森林洪泛区池塘，草地洪泛区池塘与湿地中超过在河中.(参考文献 31579)

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=0.00759 (0.00453 - 0.01269), b=2.98 (2.84 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

营养阶层 (Ref. 69278): 3.7 ±0.3 se; based on diet studies.

回复力 (Ref. 120179): 高度, 族群倍增时间少于 15个月 (tm=1; K=0.89; mean Fec=9,596).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
