Scientific Details

Meristics.
Dorsal fin spines/rays: 9-14; 40-50
Anal fin spines/rays: 39-52
Caudal fin rays: 24
Pectoral fin rays: 21-26

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Order level detail.
A diverse group of mostly benthopelagic fishes found worldwide. Gadiform fishes live in cool to cold water habitats ranging from the deep-sea to inshore coastal waters; two species live in freshwater. The group comprises 10 families and more than 600 species, including many commercially important cods, grenadiers and hakes. More than half the species belong to a single family, the Macrouridae, or grenadiers, the dominant benthopelagic fishes in deep slope waters of the world. Seven gadiform families occur in Australian waters.
Gadiform fishes have long-based dorsal and anal fins, pelvic fins usually inserted below or in front of the pectoral fins, mostly cycloid (smooth) scales and lack fin spines. Many species are bioluminescent.

Family level detail.
Body long, slender, tapering to a narrow caudal peduncle with a distinct symmetrical caudal fin. Morids lack fin spines, have reduced pelvic fins with widely separate fin bases positioned under the head, a chin barbel and two to three dorsal fins, the last usually long-based and sometimes divided into two parts. All have a unique connection between the front of the swimbladder and the sound receiving parts of the skull and brain.
