Etymology
Gymnocranius means "naked skull" and it was originally a subgeneus of Dentex distinguished by having no scales on the crown.[5]

Characteristics
Gymoncranius fishes are medium to large breams, have oval shaped, laterally compressed bodies with a convex profile in front of the eye and a steeply sloping snout. In adults there is frequently a bony ridge on the nape and a bony shelf above the front of the eye.
Distribution and habitat
Gymnocranius emperors are found in the Indo-West Pacific from the coast of eastern Africa[8] and the Indian Ocean to the western and central Pacific Ocean. They are typically found in waters between 10 and 80 m (33 and 262 ft) deep over substrates of sand or rubble on continental coasts, although some species can be found off islands.[7]
Biology
Gymnocranius emperors are normally solitary, although one species G. griseus.. aggregates in schools. They are predators of benthic invertebrates.[7]
