A flatfish is a member of the order Pleuronectiformes of ray-finned demersal fishes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward.
Polyipnus is a genus of oceanic ray-finned fish in the family Sternoptychidae. This is the largest genus of the marine hatchetfishes subfamily Sternoptychinae and indeed of the entire Sternoptychidae. It is not quite as apomorphic as their relatives; it may be that the genus is actually a paraphyletic assemblage of less advanced Sternoptychinae and would need to be split.
Sebastes is a genus of fish in the family Sebastidae, most of which have the common name of rockfish. A few are called ocean perch, sea perch or redfish, instead. Most of the Sebastes species live in the north Pacific, although two live in the South Pacific/Atlantic and four live in the North Atlantic. The coast off Southern California is the area of highest rockfish diversity, with 56 species living in the Southern California Bight.
Midshipman fish belong to the genus Porichthys of toadfishes. They are distinguished by having photophores and four lateral lines. Typical midshipman fishes, such as the plainfin midshipman, are nocturnal and bury themselves in sand or mud in the intertidal zone during the day. At night they float just above the seabed. Some species have venomous dorsal spines and are capable of inflicting serious injuries if handled.
Diaphus is a genus of lanternfishes. It is the most species rich lanternfish genus.

The hornyhead turbot is a flatfish of the family Pleuronectidae. It is a demersal fish that lives on soft sand and mud bottoms at depths of between 9 and 200 metres.

It can grow up to 37 centimetres (15 in) in length.

Liparis is a large genus of snailfish from the northern hemisphere. They are very common in temperate and cold waters. Chernova (2008) has proposed that the genus should be subdivided into five subgenera: Liparis, Neoliparis, Lycocara, Careliparis, and Lyoliparis.
