Sebastolobus

Sebastolobus, the thornyheads, is a genus of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. These fishes are native to the northern and eastern Pacific Ocean. They are generally found in deep waters.

==Taxonomy== Sebastolobus was first described as a genus by the American ichthyologist Theodore Gill in 1881 with Sebastes macrochir, a species described, with its type locality given as Japan, by the German-born British ichthyologist and herpetologist Albert Gunther in 1877. It is the type genus of the tribe Sebastolobini, one of two in the Sebastinae, a subfamily of the family Scorpaenidae. The generic name is a compound of Sebastes, the original genus of the type species, and lobus, "lobed", a reference to the lower rays of the pectoral fins being widened into tongue-shaped lobes.
