Platycephalidae
These authorities consider the Platycephalidae to belong to the suborder Platycephaloidei, along with the families Bembridae, Parabembridae, Hoplichthyidae and Plectrogeniidae within the Perciformes.The basal Platycephalinae species are confined to southern Australia and the more derived taxa have diversified in the tropical Indo-West Pacific.[13] Flatheads are mostly marine demersal fish, often resting directly on the seabed, sometimes partially buried in sand or mud.As flatheads are ambush predators they are expected to be relatively sedentary and not move large distances as adults.However, recent research has shown that part of the population of some flathead species makes long-distance movements or spawning migrations.
