These workers retain the Cottoidei as a suborder within the Perciformes while reclassifying Hexagrammoidea as the infraorder Hexagrammales. The family Zaniolepididae has been included within the Hexagrammidae, as the subfamilies Zaniolepidinae and Oxylebiinae, but Fishes of the World and Betancur et al classify these taxa as distinct from the Hexagrammidae.

Hexagrammidae have cirrhi but do not have ridges or spines on their heads, They have between one and five lateral lines and may have cycloid or ctenoid scales. There is a single dorsal fin which is notched and contains between 16 and 28 spines and 11 and 30 soft rays. There is a single spine and 5 soft rays in the pelvic fin. The front nostril on each side of the snout is well developed but the rear nostril may be absent or if it is there it is merely a small pore. The anal fin may have upn to 3 spines, or there may be no spines, and 6 or 7 soft rays. There is no swimbladder.

Hexagrammidae is endemic to the North Pacific Ocean where they are found in the subarctic and temperate regions, with a single species, the whitespotted greenling Hexagrammos stelleri, being found in the Arctic Ocean too. They occur from the intertidal zone to as deep as but most are found in waters of depths of less than on the continental shelf.

Hexagrammidae greenlings are demersal fishes, except for the pelagic Pleurogrammus, and they feed on crustaceans, polychaetes, small fishes and fish eggs.

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.
