簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 65 - 82; 臀棘: 0; 臀鰭軟條: 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).
淡又淡黃色的顏色促進鑑定。 頭部橢圓形的在背部的輪廓中; 吻圓的。 額骨囪門通常短與蹲著的;(唯一的-形狀的') 後頭骨囪門小而橢圓形的。 那眶上的與那皮蝶骨的' 硬骨變成縫合。 齒板小的。 胸棘結實的而且些微地彎曲。 鰓耙長的而且遠遠地豎立。 鰓前的器官發展良好的。 側線的第二感覺管的開口在身體上呈現不規則的白色斑點。
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).
發現更豐富的在森林洪泛區池塘，草地洪泛區池塘與濕地中超過在河中.(參考文獻 31579)
