Malapteruridae (Electric catfishes)
Etymology: Malapterurus: Greek, mala = a lot of + Greek, pteron = fin + Greek, oura = tail (Ref. 45335); punctatus: From the Latin "punctum" = little spot, in reference to the finely spotted dorsum and flank typical of this species (Ref. 44050).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
; Água doce bentopelágico. Tropical
Africa: St. Paul (or Diani) River system (Sierra Leone) to the Cavally River system (Liberia/Ivory Coast) (Ref. 44050, 57130). Also reported from the Waanje River (Sierra Leone)(Ref. 44050)
