Actinopterygii (ray-finned fishes) > Osteoglossiformes (Bony tongues) > Mormyridae (Elephantfishes)
Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335);  pulsivertens: The species name comes from the Latin 'pulsus', meaning impulse, beating; and from 'vertere', meaning to turn, exchange; the name describes the unusual EOD waveform of the species (Ref. 85331).

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

Freshwater; benthopelagic.   Tropical

Short description Morphology | Morphometrics

Diagnosis: Petrocephalus pulsivertens is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with at least 25 branched rays; anal fin with at least 31 branched rays; mouth large, the ratio head length and mouth width between 2.0 and 3.7; 15-21 teeth in the upper jaw; 24-30 teeth in the lower jaw; and eye large, the ratio head length and eye-diameter between 3,2 and 3,5 (Ref. 85331). Pigmentation pattern consists of two distinctive melanin markings (black patches): (1) a distinct ovoid mark below the anterior base of the dorsal fin; and (2) a crescent-like mark, sometimes diffuse, centered at the base of the caudal fin and extending onto the upper and lower parts of the caudal fin (Ref. 85331).

Biology     Glossary (e.g. epibenthic)

The EOD waveform of Petrocephalus pulsivertens resembles an inverted-polarity version of the 'typical' Petrocephalus EOD (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 (0.00707 - 0.03721), b=2.83 (2.65 - 3.01), 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 (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
