A flathead is one of a number of small to medium fish species with notably flat heads, distributed in membership across various genera of the family Platycephalidae. Many species are found in estuaries and the open ocean in the Indo-Pacific, especially most parts of Australia where they are popular sport and table fish. Flathead can grow at least 1 metre (3.3 ft) in length and 18 kilograms (40 lb) in weight,[1] with dusky flathead (Platycephalus fuscus) being the biggest, although fish this size are seldom caught.[2]
