Short description Morfología | Morfometría

Petrocephalus grandoculis is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: very small mouth (mouth width 5,2-6,1 times in head length), 8-11 teeth in the upper jaw, lower jaw with 18-22 teeth, eye large (eye diameter 2,8-3,2 times in head length), snout short, dorsal fin with 24-26 branched rays, anal fin with 30-33 branched rays (Ref. 85331). Pigmentation pattern consists of two melanin markings (black patches): (1) a distinct, although generally weak, round black mark on each side of the body below the anterior base of the dorsal fin (first to fifth rays); and (2) a crescent-like mark at the base of the caudal fin on each side, not extending onto the rayed portions of the upper and lower caudal fin lobes (Ref. 85331).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00704 - 0.03738), b=2.83 (2.65 - 3.01), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
