Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335);  petersi: The species name petersi is given in honour of the German herpetologist Wilhelm C.H. Peters who had carried out a major fish survey of the lower Zambezi region, and discovered many of the endemics and other widespread species during his 'Naturwissenschaftliche Reise nach Mossambique 1842-1848' (Ref. 91771).

Biology     Glossary (e.g. epibenthic)

Habitat of type locality is a medium-sized stream, sand substrate with lots of leaf litter and marginal grass; prefers freshwater (<1% salinity) (Ref. 91771).

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 (0.00697 - 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).
