Short description Morphology | Morphometrics

Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 13-15; Anal spines: 3; Anal soft rays: 10 - 11. Diagnosis: body rather elevated (body depth 46.9-51.6% SL) (Ref. 53405). Head profile rounded (Ref. 81260). Outer teeth on jaws bicuspid (Ref. 53405), gracile (Ref. 81260) and spatulated (Ref. 53405, 81260). Lower pharyngeal jaw teeth relatively small and narrow near posterior border of bone, forming an almost felt-like covering (Ref. 81260). Micro-gillrakers present; adults (> 150 mm) with a series of dark blotches in the middle of the flanks (sometimes body entirely blackish) (Ref. 53405, 81260). Juveniles with 7-9 large vertical bands (Ref. 53405). Ventral scales with central red spot; 12 or more rakers on lower limb of first gill arch (Ref. 81260).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: coastal lagoons and lower river courses from the Tabou River (Côte d'Ivoire) to the Kribi River (Cameroon), but absent from the area between the Pra River (Ghana) and Benin (Ref. 53405). Also recorded from the lower Ntem, Cameroon (81260).

Biology     Glossary (e.g. epibenthic)

Live in still or flowing waters in rocky or mud-bottom areas (Ref. 44894). Occur in warm springs and mud-bottomed to sand-bottomed canals (Ref. 5723). Consume plant matter. Reache sexual maturity at 10-15 centimeters length. Parents prepare nest site on logs, leaves and other debris. The eggs (600-3300 per female) are guarded by the parents and hatch in 1-3 days. Parental care of the brood continues until the fish are about 2.5-3.0 centimeters (Ref. 44894). Substrate brooder (Ref. 81260). Maximum size was recorded at 39.4 cm TL (Ref. 40637).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.01973 - 0.03054), b=2.97 (2.92 - 3.02), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  2.1   ±0.0 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 2,000).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
Price category (Ref. 80766):   Unknown.
