Flatheads are the members of the Platycephalidae family. They are found in the Indo-Pacific oceans. They have elongated body, depressed head, upward directed eye and large mouth with lower jaw longer than upper jaw. Their pelvic fins are behind pectoral base and first dorsal spine short, isolated or scarcely connected to second spine.
Flatheads are benthic fishes frequently found burying in the bottom, on mud or sand of the continental shelf from 10 to 300 meters depth. However, most of them are found at less than 100 meters. They feed mainly on crustaceans and small fishes.
There are 18 genera and about 74 species worldwide. Malaysia has about 20 species.
