Africa: Nyong (Ref. 81644), Kribi and Lobi/Lobe (Ref. 248, 78218, 81644) in Cameroon, Ntem River in Cameroon (Ref. 248, 78218, 81644), Equatorial Guinea (Ref. 248, 78218) and Gabon (Ref. 81644), and the Ogooué in Gabon (Ref. 81644). Reports from the Sanaga and Dja in Cameroon (Ref. 51193) questionable and unconfirmed in Ref. 248 or 78218, but a collection point is present on the distribution map in Ref. 81644.

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 74 - 85; ऐनल सौफट रेज़: 61 - 71; जानवरों की रीड़ का जोड़: 60 - 63. Diagnosis: body extremely elongate (depth 9.3-13.3% SL, mean 11.0); 9-12 rakers on first gill arch (Ref. 81644). Head rounded in dorsal outline (Ref. 248), rather short (HL 18.3-22.8% SL, mean 20.2) and wide (width 14.1-17.0% SL, mean 15.4)(Ref. 81644). Snout broadly rounded (Ref. 248). Eyes small and laterally placed (Ref. 248). Interorbital width large (45.4-50.7% HL, mean 47.7)(Ref. 81644). Postorbital margin not entirely covered with bone; frontal fontanelle long and narrow; occipital fontanelle long and oval-shaped; supra-orbital and "dermosphenotic" bones separated; tooth plates relatively broad; pectoral spine straight (Ref. 248). Pectoral spine slightly serrate on its anterior face, with serrations downward oriented (Ref. 248, 81644). Gill rakers relatively long and distantly set; suprabranchial organ well developed (Ref. 248). Openings of secondary sensory canals show a regular pattern (Ref. 248, 81644). Coloration: preserved specimens with uniform colouration; back, flanks and upper parts of paired fins dark brown to reddish brown; ventrum and lower parts of paired fins pale brown to beige (Ref. 81644).

Facultative air-breathing (Ref. 126274); Practically nothing is known about the biology of this species (Ref. 78218).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00357 - 0.01766), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
