Morfologie | Morfometrie
Dorsale zachte stralen (totaal): 13-16; Anale zachte stralen: 8. Diagnosis: last simple ray partly ossified at base (no strong spine) and distinctly longer than head; lower reduced, substituted by horny sheath; 9-12 (usually 10) dorsal fin branched rays; scale formula 3.5-4.5/23-29/3.5-4.5; 2 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle (Ref. 2940, 81282).
Barbus wurtzi has differences in meristic and morphometric characteristics depending on which population; body depth varies between 26-33% in Guinean rivers and 34-43% in the Cavally and Nipoué rivers; the caudal peduncle length-height ratio is approximately 100% in Cavally-Nipoue and reaches an average of 140% in Guinean rivers; population east of Ivory Coast has intermediary characteristics such as number of scales above and below the lateral line: 4.5 in Guinea and Ivory Coast, 3.5 in western part of Ivory Coast and east of Liberia (Ref. 2940). Maximum TL was recorded at 27.5 cm (Ref. 2801).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00448 - 0.01544), b=2.97 (2.81 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisch niveau (Ref.
