Thysanophrys is a genus of marine, demersal ray-finned fish belonging to the family Platycephalidae.

Thysanophrys was first formally proposed as a genus in 1898 by the Australian ichthyologist James Douglas Ogilby with Platycephalus cirronasus, which had been described from Botany Bay in New South Wales in 1848 by John Richardson, as its type species.

[1][2] This genus is classified within the family Playtcephalidae, the flatheads which the 5th edition of Fishes of the World classifies within the suborder Platycephaloidei in the order Scorpaeniformes.

[4] Thysanophrys contains 10 species:[5][6] Thysanophrys flatheads do noy have any elongation of the upper lobe of the caudal fin with no elongated filament extending out from that fin.

the second being equal in height to the third, while the second dorsal fin has no more than 12 soft rays.
