Gadiformes in the context of "Physoclist"

Hake (/heɪk/) is the common name for fish in the Merlucciidae family of the northern and southern oceans and the Phycidae family of the northern oceans. Hake is a commercially important fish in the same taxonomic order, Gadiformes, as cod and haddock.

The Gadidae are a family of marine fish, included in the order Gadiformes, known as the cods, codfishes, or true cods. It contains several commercially important fishes, including the cod, haddock, whiting, and pollock.

Most gadid species are found in temperate waters of the Northern Hemisphere, but several range into subtropical, subarctic, and Arctic oceans, and a single (southern blue whiting) is found in the Southern Hemisphere. They are generally medium-sized fish, and are distinguished by the presence of three dorsal fins on the back and two anal fins on the underside. Most species have barbels on their chins, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans.

The Merlucciidae, commonly called merluccid hakes /mərˈluːtʃɪd/, are a family of cod-like fish, containing two genera. They are the only member of the suborder Merlucciodei. They are native to cold water in the Atlantic and Pacific oceans, and typically are found at depths greater than 50 m (160 ft) in subtropical, temperate, sub-Arctic or sub-Antarctic regions.

These predatory fish are up to 1.55 m (5 ft 1 in) in length, though most only reach about half that length, inhabiting the waters of the continental shelf and upper continental slope, where they feed on small fish such as lanternfishes. Several species are important commercial fish, for example the North Pacific hake (Merluccius productus) that is fished off western North America.

The Phycidae are a family of hakes in the order Gadiformes. They are native to the Atlantic Ocean, but the juveniles of some species enter estuaries. Sometimes this family is classified as the subfamily Phycinae of the cod family, Gadidae, but Eschmeyer's Catalog of Fishes currently classifies it as a distinct family within the Gadoidei.
