Etymology: grenfelli: Named for the collector of the type specimen, Mr. G. Grenfel, Protestant missionary (Ref. 43912).
Eponymy: George Grenfell (1849–1906) was an explorer and a Baptist missionary in Cameroon (1875–1877) and the Congo Free State (Democratic Republic of the Congo) (1877–1906). [...] (Ref. 128868), visit book page.

Africa: lower, middle and upper Congo River basin, including Pool Malebo (= Stanley Pool); Ogooué and Nyanga basins in Gabon; Ntem-Campo, Nyong and Lokoundje basins in Cameroon (Ref. 43912). Also in the Mitemboni River (Gabon-Equatorial Guinea border) and lower Nkomi River basin (Gabon)(Ref. 81643). Reports from the Lali River (upper Kouilou basin) in Republic of Congo or from the Chad basin are based on misidentified specimens; presence in the Ruzisi unlikely, based on a single specimen that is probably mislabelled (Ref. 43912).

Biologi     Ordlista (t.ex. epibenthic)

Omnivorous or predominantly carnivorous, feeding on fruits, leaves, grains, insect larvae and nymphs, and small fish; very voracious; juveniles found in floodplains during the rainy season, often hidden under floating trunks of trees which seems a favorite place for juvenile Schilbe and numerous other fish larvae; active swimmer, especially during the night, probably resting near the bottom during daytime (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Important species in fishery terms (Ref. 78218). Flesh of this fish very tasty, its price rather elevated (Ref. 43912).
