Kurzbeschreibung Morphologie | Morphometrie

Diagnosis: Petrocephalus odzalaensis is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin shorter than anal fin; dorsal fin with a maximum of 22 branched rays; anal fin with a minimum of 27 branched rays; mouth sub-terminal, ratio between head length and mouth position is between 4,2 and 5,0; and eye small, the ratio head length and eye-diameter between 3,7 and 4,2 (Ref. 85331). Body pinkish-gray, darker dorsally, with the presence of three distinct pigmentation patches: (1) a distinct ovoid black mark situated below the anterior base of the dorsal fin on each side of the body; (2) a small black mark at the base of each pectoral fin; (3) an ovoid black mark on each side that is centered at the base of the caudal fin, not extending onto the upper and lower lobes of this fin (Ref. 85331).

Bayesian length-weight: a=0.01585 (0.00697 - 0.03603), b=2.85 (2.67 - 3.03), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
