Dorsal spines (total): 1-1; Dorsal soft rays (total): 5-6; Anal soft rays: 41-66. Diagnosis: 8-13 gill rakers on lower limb of first gill arch; 41-66 branched anal-fin rays; eyes positioned laterally (Ref. 57127). In West Africa, this species usually lacks an adipose fin, but specimens with a rudimentary adipose fin may be occasionally present (Ref. 57127).
Description: anal fin long, extending from vent almost to origin of caudal fin; 4 pairs of short, circum-oral barbels (Ref. 34290).
Coloration: live young individuals (to about 150 mm SL) with a peculiar colour pattern: head and back dark brown, with two brownish or blackish bands on sides, one along lateral line, other above anal-fin base; this colour pattern disappears with growth: head and back remain dark brown, but the lateral bands fade progressively and the sides become more or less whitish or silvery (Ref. 57127). Preserved specimens: silvery colour of the body disappears almost completely (Ref. 57127).
