Setarchidae

Setarchinae, the deep-sea bristly scorpionfishes, is a small subfamily of deep-sea ray-finned fishes, it is part of the family Scorpaenidae. They are small marine fishes, growing up to 25 cm, and are found in tropical and subtropical waters throughout the world.

==Taxonomy== Setarchinae, or the family Setarchidae, were first described as a taxon by the Japanese ichthyologist Kiyomatsu Matsubara in 1943. The grouping is treated as a subfamily of the Scorpaenidae within the order Scorpaeniformes by the 5th Edition of Fishes of the World. However, other authorities, such as FishBase, regard the taxon as a family within the suborder Scorpaenoidei, part of the Perciformes. The name of the subfamily comes from Setarches which was described by the English zoologist James Yate Johnson in 1862 but Johnson did not explain what the name alluded to, it may be derived from saeta meaning "bristle".
