The green fishes (Hexagrammidae) are bony fish from the order of the perch-like (Perciformes). They live on the shores of the northern Pacific , from Japan to California .

features

They are elongated, predatory, bottom-dwelling fish without a swim bladder . The head is not bristled, they only have one dorsal fin, which has a dent between the hard-rayed and soft-rayed part. The first part has 16 to 28 hard rays, the second 11 to 30 soft rays. The pelvic fins each have one hard and five soft rays, the anal fin no to a maximum of three hard and six or seven soft rays. The lateral line organ is uniform or divided into up to five parts. Most green bodies are about half a meter long, Ophiodon elongatus 1.5 meters.

The animals have not yet been explored much. Some species are fished commercially.

Systematics

There are eight species in three genera , all of which are placed in their own subfamilies.

• Green compacts (Hexagrammidae)
  • Hexagramminae
    • Hexagrammos (6 types)
  • Ophiodontinae
    • Ophiodon (1 kind)
  • Pleurogramminae
    • Pleurogrammus (1 species)

The crested greenlings ( Zaniolepis ) and the anemone guard ( Oxylebius pictus ), which Nelson (2006) and Fishbase classify as Hexagrammidae, have recently been placed in the independent family Zaniolepididae .
