• Any fish of the genus Platycephalus found in southern Australian waters. They are usual caught commercially as a by-catch, but are very popular with recreational fishermen. All are long and thin with a flat head and weigh from 1 to 3 kg, though they can reach 6 kg.The sand flathead, P. bassensis, is caught in Victorian and Tasmanian waters and is distinguished from other varieties by the spines in front of the gill cover and a large black blotch on the tail. The dusky flathead, P. fuscus, is found as far as up southern Queensland. They are considered excellent eating and they taste better the bigger they are. Generally prepared as oblique slices from fillets. They can be eaten as sushi.
