duri punggung lunak (Keseluruhan (total)) : 24; Sirip dubur lunak: 28 - 29. Petrocephalus christyi is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with 22-24 branched rays, anal fin with 25-29 branched rays, eye large (HL/ED=3,1-4,2), mouth small, 9-13 teeth in the upper jaw, 17-22 teeth in the lower jaw (Ref. 85331). Melanin pattern consisting of two characteristic black patches: (1) a distinct round mark below the anterior base (first to the fifth rays) of the dorsal fin; and (2) a somewhat diffuse crescent-like mark, centered at the base of the caudal fin and extending onto the fleshy dorsal and ventral lobes of this fin (Ref. 85331).

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=0.01585 (0.00843 - 0.02981), b=2.87 (2.71 - 3.03), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

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

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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