- Flathead (fish)
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 familyPlatycephalidae . Many species are found in the Indo-Pacific, especially most parts ofAustralia where they are popular sport and table fish. They inhabit estuaries and the openocean .Anatomy and morphology
Flathead are notable for their unusual body shape, upon which their hunting strategy is based. Flathead are dorsally compressed, meaning their body is wide but flattened and very low in height. Both eyes are on the top of the flattened head, giving excellent binocular vision to attack overhead prey. The effect is somewhat similar to
flounder s. In contrast to flounder, however, flathead are much more elongated, the tail remains vertical, and the mouth is large, wide and symmetrical. Flathead use this body structure to hide in sand (their body colour changes to match their background), with only their eyes visible, and explode upwards and outwards to engulf small fish and prawns as they drift over the hidden flathead.Fact|date=April 2007Habitat
Dusky flathead are found in estuaries and coastal bays, from Cairns in
Queensland to theGippsland Lakes in Victoria. They occur over sand, mud, gravel and seagrass and can inhabit estuarine waters up to the tidal limit.Fact|date=April 2007Oceanic flathead species (sand flathead, tiger flathead, bar-tailed flathead) are, as named, generally located more offshore than the dusky flathead, frequenting the sandy zones around and between coastal reefs, although bar-tailed flathead occur in many esturine environments, for example the Swan/Canning River System in Perth.Fact|date=April 2007
Importance to humans
Fishermen catch flathead on a variety of baits and artificial lures all year round, but they are more commonly caught during summer. Only a handful of the many flathead species are regularly caught by fishermen. Most flathead species are considered excellent eating.
