'''''Sebastiscus''''' is a [genus](/source/genus) of marine [ray-finned fish](/source/ray-finned_fish) belonging to the [subfamily](/source/subfamily) [Sebastinae](/source/Sebastinae) part of the [family](/source/Family_(taxonomy)) [Scorpaenidae](/source/Scorpaenidae). These fishes are native to the western [Pacific Ocean](/source/Pacific_Ocean). They are collectively called '''sea ruffes''' and resemble the rockfishes in the genus ''[Sebastes](/source/Sebastes)'', but are usually smaller and have a different pattern.

==Taxonomy==
''Sebastiscus'' was first formally described as a [subgenus](/source/subgenus) of ''Sebastes'' by [David Starr Jordan](/source/David_Starr_Jordan) and [Edwin Chapin Starks](/source/Edwin_Chapin_Starks) in 1904 with ''Sebastes marmoratus'', which had been [described](/source/Species_description) by [Georges Cuvier](/source/Georges_Cuvier) in 1829, as its [type species](/source/type_species). It was regarded as a subgenus up to 1984 when it was proposed as a valid genus,<ref name = CofF>{{Cof family | family = Sebastidae | access-date = 18 December 2021}}</ref> albeit within the same tribe Sebastini as the speciose genus ''Sebastes'', which is one of the [tribe](/source/Tribe_(biology))s of the [subfamily](/source/subfamily) [Sebastinae](/source/Sebastinae) within the [family](/source/Family_(taxonomy)) [Scorpaenidae](/source/Scorpaenidae) and the [order](/source/Order_(biology)) [Scorpaeniformes](/source/Scorpaeniformes).<ref name = Nelson5>{{cite book  |title=Fishes of the World |edition=5th |author1=J.

==Characteristics==
''Sebastiscus'' was described by Jordan and Starks as being similar to  the [subgenus](/source/subgenus) ''Sebastodes'' of the genus ''Sebastes'', the Pacific rockfishes were considered to be separate from the Atlantic redfishes which bore the generic name Sebastes. They also stated that these fishes bore a close resemblance to the fishes in the subgenus ''Pteropodus'' but differed in the possession of 12 [dorsal fin](/source/dorsal_fin) spines and in the vertebrae count. These characteristics were thought to be similar to the genus ''[Scorpaena](/source/Scorpaena)''. ''Sebastiscus'' was differentiated from ''[Helicolenus](/source/Helicolenus)'' by having a well developed swim bladder.<ref name = Kendall>{{cite journal | author = Arthur W.

==Distribution and habitat==
''Sebasticus'' species are found in the western Pacific Ocean from Japan and Korea south to the Philippines.<ref name = Fishbase/> Extralimital records of ''S. marmoratus'' in Australia and Norway are thought to probably be a result of fish being transported to these locations in the ballast water of ships.<ref name = FofA>{{cite web | url = https://fishesofaustralia.net.au/home/species/3136 | author = Bray, D.J. | year = 2021 | title = ''Sebastiscus marmoratus'' | work = Fishes of Australia | access-date = 21 December 2021 | publisher= Museums Victoria}}</ref><ref name = Hansen>{{cite journal | author1 = Haakon Hansen | author2 = Egil Karlsbak | year = 2018 | title = Pacific false kelpfish, Sebastiscus marmoratus (Cuvier, 1829) (Scorpaeniformes, Sebastidae) found in Norwegian waters | journal = BioInvasions Records | volume = 7 | issue = 1 | pages = 73–78 | doi = 10.3391/bir.2018.7.1.11| doi-access = free }}</ref> They are shallow water coastal species.<ref name = Kendall/>
