Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 26 - 35; Radios blandos anales: 40 - 51; Vértebra: 53 - 60. Diagnosis: length of rayed dorsal fin 27-36% standard length; 26-35 dorsal-fin rays; length of adipose fin 24-34% of standard length (Ref. 57129). Strong, downward-pointed serrations on the anterior part of the pectoral spine (Ref. 270, 57129). Width of vomerine tooth plate 20.8-25.0%, width of premaxillary tooth plate 25.2-30.9% of head length; adipose fin uniformly coloured (Ref. 57129). Eyes superolateral; frontal fontanelle long and narrow; occipital fontanelle oval-shaped; head completely covered with bones; suprabranchial organ well developed; tooth plates relatively narrow; openings of secondary sensory canals regularly placed (Ref. 270). Coloration: preserved specimens: grey, greyish-brown to dark brown on back and sides, pale brown on belly; some individuals show a marbled colour pattern; caudal and adipose fins uniformly coloured (Ref. 57129).

Facultative air-breathing (Ref. 126274); Max. size in West Africa reported as 510 mm TL (Ref. 57129).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00489 - 0.01483), b=2.91 (2.76 - 3.06), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.7 ±0.7 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
