see text Hexagrammidae, the greenlings, is a family of marine ray-finned fishes belonging to the suborder Cottoidei in the order Perciformes.

Hexagrammidae was first proposed as a family in 1888 by the American ichthyologist David Starr Jordan.

These workers retain the Cottoidei as a suborder within the Perciformes while reclassifying Hexagrammoidea as the infraorder Hexagrammales.

[4][5] Placing these two families in their own monotypic superfamilies was originally proposed in 1994 by Gento Shinohara.

[2] Hexagrammidae greenlings are fished for, the coastal species are fished for using hook and line and spears and in the late 20th and early 21st centuries the kelp greenling (Hexagrammas decagrammus) has become a target of a commercial fishery, while historically the lingcod (O. elongatus) and the atka mackerels of the genus Pleurogrammus have been the most targeted species.
