Species description and etymology edit

Channa pleurophthalma was formally described in 1851 by the Dutch ichthyologist Pieter Bleeker as Ophiocephalus pleurophthalmus with the type locality given as Bandjarmasin on Borneo.[2] The specific name is a compound of pleuro- meaning "side" and ophthalma meaning "eyed" a reference to the 2-3 eyespots or ocelli on its flanks and the single eye spots on the gill cover and on its caudal fin.[3]
