Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 26-35; Raggi anali molli: 42 - 52; Vertebre: 55 - 61. Diagnosis: length of rayed dorsal fin 27-36% standard length; 26-35 dorsal-fin rays; length of adipose fin 24-34% standard length; width of vomerine tooth plate 25.0-32.2%, and width of premaxillary tooth plate 29.5-36.9% head length (Ref. 57129, 81644). Pectoral spine with strong, downward-pointed serrations on the anterior side (Ref. 270, 57129, 81644). Length of pectoral fin 12.7-18.0% SL (mean 16) (Ref. 81644). Posterior part of adipose fin blackish (Ref. 4967, 57129). Caudal fin with a whitish cross-bar (Ref. 57129). Head long, broad and somewhat rectangular in dorsal outline (Ref. 270), its length 28.4-35.9% SL (Ref. 81644). Snout broadly rounded; eyes superolateral in position; frontal fontanelle long and narrow; occipital fontanelle oval-shaped; tooth plates wide; suprabranchial organ well developed; caudal fin barred; openings of secondary canals hardly visible but display a regular pattern (Ref. 270). Coloration: preserved specimens: grey, greyish-brown to dark brown on back and sides, and pale brown to whitish on belly; some individuals marbled, particularly on posterior part of body; caudal fin often crossed by several vertical bars, one of which is whitish, hind margin of fin often white-edged; posterior part of adipose fin darker than anterior part (Ref. 57129, 81644).

Biologia     Glossario (es. epibenthic)

An uncommon species which inhabits large rivers (Ref. 4967). Largest freshwater species in southern Africa; occurs in large deep rivers within the mainstream or in deep pools and lakes or backwaters (Ref. 7248, 78218). Most active at night, feeding on any available food, including invertebrates and insects when small, fish and other small vertebrates when large; scavenges off large carcasses and offal from riverside villages; live for 12 or more years (Ref. 7248). Maximum reported size for West Africa and Lower Guinea: 610 mm TL (Ref. 57129, 81643).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00581 - 0.00991), b=2.93 (2.86 - 3.00), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.66 se; based on food items.
Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (K=0.11; tmax > 11; Fec > 10,000).
Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100) .
