Sebastinae

Sebastinae is a subfamily of marine fish belonging to the family Scorpaenidae in the order Scorpaeniformes. Their common names include rockfishes, rock perches, ocean perches, sea perches and rockcods. Despite the latter name, they are not closely related to the cods in the genus Gadus, nor the rock cod, Lotella rhacina.

Taxonomy

Sebastinae, or Sebastidae, was first formally recognised as a grouping in 1873 by the German naturalist Johann Jakob Kaup.<ref name = VDLEF>Template:Cite journal</ref> Some authorities recognise this family as distinct from Scorpaenidae. FishBase, a finfish database generated by a consortium of academic institutions, does,<ref name=FishBase>Template:FishBase family</ref> but the United States Federal government's Integrated Taxonomic Information System<ref>Template:ITIS</ref> and the 5th Edition of Fishes of the World do not, FotW classify it as a subfamily of the Scorpaenidae.<ref name = Nelson5>Template:Cite book</ref> Eschmeyer's Catalog of Fishes classifies it as a subfamily of Scorpaenidae, but also classifies the Sebastolobinae (previously considered a tribe of the Sebastinae) as a different subfamily.<ref name=":132">Template:Cite web</ref>

There is a venom gland in the spines of the dorsal, anal and pelvic fins. The largest species is the shortraker rockfish ( Sebastes borealis) which attains a maximum total length of Template:Cvt while the smallest species is Sebastes koreanus which reaches a maximum total length of Template:Cvt.<ref name = FishBase/>

Distribution and habitat

Sebastinae rockfishes are found in the Pacific, Indian and Atlantic Oceans with most species in the largest genus, the ovoviviparous Sebastes with over 100 species, in the North Pacific. They can be found in marine and brackish waters.<ref name = FishBase/>
