Channa pleurophthalma, the ocellated snakehead is a species of Southeast Asian freshwater fish in the snakehead family.

Description

Channa pleurophthalma can reach a length of about 40 centimetres (16 in).[1] The body is cylindrical, laterally flattened and has an iridescent greenish or bluish basic color, with two or three big black patches, which are outlined in orange and an additional ocellus on both the opercle and tail fin. The belly is usually yellowish. The long dorsal fin has 40-43 fin rays, while the soft anal fin has 28-31 rays.[1] This species is caught for human consumption and for the aquarium trade.

Distribution and habitat

This species is present in Indonesia in Sumatra and in Borneo.[1] These fish prefer areas with black and clear waters.[1]

Species description and etymology

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]
