Editing Cod (section)

===Other species===
Some fish commonly known as cod are unrelated to ''Gadus''. Part of this name confusion is market-driven. Severely shrunken Atlantic cod stocks have led to the marketing of cod replacements using [[culinary name]]s of the form "''x'' cod", according to culinary rather than phyletic similarity. The common names for the following species have become well established; note that all inhabit the [[Southern Hemisphere]].

==== Perciformes ====
Fish of the [[order (biology)|order]] [[Perciformes]] that are commonly called "cod" include:
*[[Blue cod]] ''Parapercis colias''
*[[Eastern freshwater cod]] ''Maccullochella ikei''
*[[Mary River cod]] ''Maccullochella mariensis''
*[[Murray cod]] ''Maccullochella peelii''
*[[Potato cod]] ''Epinephelus tukula''
*[[Sleepy cod]] ''Oxyeleotris lineolatus''
*[[Trout cod]] ''Maccullochella macquariensis''
*The notothen family, [[Nototheniidae]], including:
**[[Antarctic cod]] ''Dissostichus mawsoni''
***''Dissostichus eliginoides'', the [[Patagonian toothfish]], is also marketed as "cod"
**[[Notothenia microlepidota|Black cod]] ''Notothenia microlepidota''
**[[Maori cod]] ''Paranotothenia magellanica''

==== Rock cod, reef cod, and coral cod ====
Almost all [[coral cod]], [[reef cod]] or [[rock cod]] are also in order [[Perciformes]]. Most are better known as [[grouper]]s, and belong to the family [[Serranidae]]. Others belong to the [[Nototheniidae]]. Two exceptions are the [[Australasia]]n [[red rock cod]], which belongs to a different order (see below), and the fish known simply as the rock cod and as [[soft cod]] in New Zealand, ''[[Lotella rhacina]]'', which as noted above actually is related to the true cod (it is a morid cod).

==== Scorpaeniformes ====
From the order [[Scorpaeniformes]]:
*[[Ling cod]] ''Ophiodon elongatus''
*[[Red rock cod]] ''Scorpaena papillosa''
*Rock cod ''[[Sebastes]]''

==== Ophidiiformes ====
The tadpole cod family, [[Ranicipitidae]], and the [[Eucla cod]] family, [[Euclichthyidae]], were formerly classified in the order [[Ophidiiformes]], but are now grouped with the [[Gadiformes]].
