Sebastapistes is a genus of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. The fishes in this genus are found in the Indian and Pacific Ocean.
Taxonomy
Sebastapistes was first described as a genus in 1877 by the American ichthyologist Theodore Gill, Gill included 3 species within the new genus and in 1898 David Starr Jordan and Barton Warren Evermann designated Scorpaena strongia which had been described by Georges Cuvier in 1829 with its type locality given as Kosrae in the Caroline Islands, as the type species.{{Cof genus|genus=Sebastapistes|access-date=21 February 2022}} This genus is classified within the tribe Scorpaenini, in the subfamily Scorpaeninae of the family Scorpaenidae.{{cite book |title=Fishes of the World |edition=5th |author1=J.

Some authorities consider that S. nuchalis is a junior synonym of S. strongia and that Scorpaena pascuensis should be included within Sebastapistes.
Characteristics
Sebastapistes scorpionfishes are characterised by there being 12 spines in the dorsal fin, having teeth on the palatine and byhaving the rear lacrimal spine being directed diagonally downwards. The pored scales in the lateral line continue on to the caudal peduncle and they do not have a deep occipital pit. There are species in the deepwater scorpionfish genus Neomerinthe which share these characteristics with this genus but have different patterns of spines and scales on their heads, differing meristics and by living in deep water. The size of these small scorpionfishes varies from a maximum published total length of {{cvt|2.5|cm}} in S. taeniophrys up to {{cvt|11.7|cm}} in S. ballieui.
Distribution and habitat
Sebastapistes scorpionfishes are found in the Indian and Pacific Oceans from East Africa to Hawaii and Easter Island. They are mostly species of shallow, tropical coastal waters but two species S. strongia and S. perplexa extend to temperate waters off Japan.
