Actinopterygii (ray-finned fishes) > Osteoglossiformes (Bony tongues) > Mormyridae (Elephantfishes)
Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335);  valentini: This species is named in honor of Mr. Valentin Mbossi, 'pinassier extraordinaire' at Odzala National Park; his first name is used to reflect appreciation for him and to avoid confusion with a similarly named species, Petrocephalus mbossou (Ref. 85331).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic.   Tropical

Short description Morphology | Morphometrics

Diagnosis: Petrocephalus valentini is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with 19-24 branched rays; anal fin with 24-26 branched rays; eye large, the ratio head length and eye-diameter between 2.9 and 3.2; mouth very small, the ratio head length and mouth width between 4.7 and 5.8; 12 teeth or fewer in the upper jaw; and 17 teeth or fewer in the lower jaw (Ref. 85331). Pigmentation pattern subtle, including two components: (1) a pale dorsal black mark on each side of the body below the anterior base of the dorsal fin, under the second to sixth dorsal rays; (2) an ovoid mark, sometimes scarcely visible, at the base of the caudal fin, extending weakly onto the upper and lower lobes of the fin (Ref. 85331).

Estimates of some properties 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 (0.00710 - 0.03704), b=2.84 (2.66 - 3.02), 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
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
