Cods of the genus ''Gadus'' have three rounded [[Dorsal fin|dorsal]] and two [[anal fin]]s. The [[pelvic fin]]s are small, with the first ray extended, and are set under the [[gill]] cover (i.e. the throat region), in front of the [[pectoral fin]]s.<ref>{{cite journal |title=Cod's Journey Back Home—From Birth to Nursery |year=2021 |language=en |doi=10.3389/frym.2021.622088|doi-access=free |last1=Endo |first1=Clarissa Akemi Kajiya |last2=Vikebø |first2=Frode B. |last3=Yaragina |first3=Natalia A. |last4=Hjøllo |first4=Solfrid Sætre |last5=Stige |first5=Leif Christian |journal=Frontiers for Young Minds |volume=9 }}</ref> The upper jaw extends over the lower jaw, which has a well-developed [[Barbel (anatomy)|chin barbel]]. The eyes are medium-sized, approximately the same as the length of the chin barbel. Cod have a distinct white [[lateral line]] running from the gill slit above the pectoral fin, to the base of the [[caudal fin|caudal]] or tail fin. The back tends to be a greenish to sandy brown, and shows extensive mottling, especially towards the lighter sides and white belly. Dark brown colouration of the back and sides is not uncommon, especially for individuals that have resided in rocky inshore regions.

The [[Atlantic cod]] can change colour at certain water depths. It has two distinct colour phases: gray-green and reddish brown. Its average weight is {{convert|5|-|12|kg|lb|abbr=off}}, but specimens weighing up to {{convert|100|kg|lb|abbr=on}} have been recorded. Pacific cod are smaller than Atlantic cod<ref name=FBAtlantic /><ref name=FBPacific /> and are darker in colour.
