Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 1; Rayons mous dorsaux (Total): 6; Vertèbres: 29 - 31. Diagnosis: labial disk moderately developed, almost circular and not papillose, only with some weak swellings, much more subtle than those observed in other West African species; outer pair of mandibular barbels much longer than inner pair; inner auxiliary barbels absent; all teeth simple, long and straight (sometimes slightly S-shaped), those on premaxillary plates set in 2 rows; mandibular teeth, initially believed to be absent or rudimentary, in fact small and numerous, and arranged in 1-2 regular rows along entire rim of mouth; eye moderately developed; caudal fin slightly forked, with rounded lobes, lower lobe better developed than upper (Ref. 57223). Coloration: 3 dark vertical bars on sides, separated by wide lighter areas; some individuals with narrow dark vertical bar at base of caudal fin, but rest of fin-surface uniformly coloured (Ref. 57223).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
