Papyrocranus afer (Günther) ;

Reticulate knifefish

Remarks: Synonymous with Notopterus afer (Günther) , Notopterus afer congensis (Nichols & LaMonte) , Papyrochranus afer (Günther) and Paryrocranus afer (Günther) , P. afer is a reticulated knifefish, characterized by its laterally flattened body and the presence of very small scales, which contribute to its distinctive appearance. Papyrocranus afer was rarely encountered across all our study areas. However, this species is known to inhabit other Nigerian coastal river basins, with a distribution extending from the Ogun River to the Cross River.
