Cociella is a genus of marine ray-finned fishes belonging to the family Platycephalidae, the flatheads.

Cociella was first proposed as a genus in 1940 by the Australian ichthyologist Gilbert Percy Whitley as a replacement for Cocius which had been put forward by David Starr Jordan and Carl Leavitt Hubbs in 1925 but this name was unavailable as it was preoccupied by the antlion genus Cocius.,[1] described by the Spanish entomologist Longinos Navás in 1921.

[4] The name of the genus, Cociella, is a diminutive form of the original name coined by Jordan and Hubbs which is thought to be a latinisation of the Japanese name for flatheads and dragonets.

[6] The maximum recorded total length is for C. crocodilus sensu lato and is 50 cm (20 in).

[4] Cociella flatheads are found in the Indian and western Pacific Oceans from the eastern coast of Africa and the Red Sea east to New Caledonia, north to Japan and south to Australia.
