Gadiformes are an order of ray-finned fish, also called the Anacanthini, that includes the cod and its allies. Many major food fish are in this order. They are found in marine waters throughout the world and the vast majority of the species are found in temperate or colder regions. A few species may enter estuaries but only one, the burbot, is a freshwater fish.
Grenadiers or rattails are generally large, brown to black gadiform marine fish of the subfamily Macrourinae, the largest subfamily of the family Macrouridae. Found at great depths from the Arctic to Antarctic, members of this subfamily are amongst the most abundant of the deep-sea fish.
Coelorinchus is a genus of rattails.
Coryphaenoides is a genus of rattails which is found in all oceans of the world. They are found in deep waters and C. yaquinae, recorded to 7,012 m (23,005 ft), is the only member in the family known from the hadal zone.
Lucigadus is a genus of rattails.
Nezumia is a genus of rattails.
Hymenocephalus is a genus of rattails.
Hymenogadus gracilis, also known as the Graceful grenadier is a species of rattail fish. It is found at depths of 160–345 m (525–1,132 ft) in tropical and subtropical seas worldwide. This is one of the smallest of the rattails, growing to no more than 13 cm (5.1 in) in length. It is a slender fish with a large mouth, with rows of very small teeth, positioned in the underside of the skull. There is a short, thin chin barbel. It is more strikingly marked than most rattails, with bold black streaks on the head and black and silver barring over most of the body. There is a long bioluminescent organ with two lenses underneath the rear end of the body.

Lophiodes is a genus of goosefishes. It is one of four extant genera in the family Lophiidae.
Kuronezumia is a genus of rattails.
Mataeocephalus is a genus of rattails.
Trachonurus is a genus of rattails.
Parapercis is a genus of sandperches belonging to the fish family Pinguipedidae.
Bathygadinae is a subfamily of rattails in the family Macrouridae, the species of which are found in Atlantic, Indian and Pacific Ocean. These species lives in great depths. The chin barbel is usually absent in the genus Bathygadus when present barbel tiny and difficult to see without magnification. In Gadomus the chin barbel is present, usually thick and long.
Macrouroidinae is a subfamily of rattails from the family Macrouridae, it contains only two species in two genera found in most tropical and temperate ocean. These species lives in deep-water. These fishes have a huge and rounded head with consistency of water-filled balloon, eyes tiny. The chin barbel is absent.
Trachyrincinae is a subfamily of the family Macrouridae, also known as rattails. The subfamily contains two genera found in Atlantic, Indian and Pacific Ocean. These species lives in deep-water. These fishes have a long, narrow and sharply pointed snout. The chin barbel is present.
