Thysanichthys

Thysanichthys is a genus of marine ray-finned fishes belonging to the family Scorpaenidae, it is a monotypic genus with its only species being Thysanichthys crossotus. This species is found in the northwestern Pacific Ocean.

==Taxonomy== Thysanichthys was described as a genus in 1904 by the American ichthyologists David Starr Jordan and Edwin Chapin Starks when they described Thysanichthys crossotus, giving its type locality as off Ose Point in Suruga Bay in Japan. In 1914, Jordan and William Francis Thompson described a second species, Thysanichthys evides, but in 2010 this was shown to be a senior synonym of Scorpaenodes littoralis Tanaka, 1917 and was correctly classified within the genus Scorpaenodes, confirming Thysanichthys as a monotypic genus. The name of the genus Thysanichthys is a compound of thysanos which means fringe, a reference to the dermal cirri on the head and along the lateral line with ichthys, meaning fish. The specific name crossotus means "fringed".
