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.
The abyssal grenadier, Coryphaenoides armatus, is an abyssal fish of the genus Coryphaenoides, found in all the world's oceans, at depths between 800 and 4,000 m. Its adult length is 20 to 40 cm, although Fishbase gives lengths up to 1 m. The abyssal grenadier's body is unique in that it contains two dorsal spines and about 124 dorsal soft rays, which are the flexible jointed rays supporting a fin nearest to the back in the spinal column. It has no anal spines, but has 115 anal soft rays along its body. The head and eyes of this fish are very large, while the mouth is very small. The color of the abyssal grenadier is brown apart from the abdomen, which is bluish.
The rudis rattail, Coryphaenoides rudis, is a fish of the family Macrouridae, found around the world in tropical and subtropical oceans, at depths between 600 and 2,300 m. Its length is between 30 and 40 cm, although FishBase gives lengths of up to 1.1 m.

Gadella is a genus of morid cod. The species in this genus are characterised by the absence of a chin barbell, an anterior dorsal fin with 7-11 rays, a long based anal fin which has a straight profile, the outermost rays of the pelvic fin are filamentous and extend a small distance beyond the membrane. They do not have a photophore. The Gadella codlings are found around the tropical and subtropical seas around the world on the outer continental shelf to the mid continental slope. They are of no interest to fisheries.
Coryphaenoides rupestris is a species of marine ray-finned fish in the family Macrouridae. Its common names include the rock grenadier, the roundnose grenadier and the roundhead rat-tail.
