It is found along the eastern coast of Africa from Kenya to South Africa and along the southern coast of Asia into the pacific as far east as Polynesia, north as far ast the Ryukyu Islands of southern Japan and south to Australia. In Australia its range extends from the Ningaloo Reef in Western Australia along the northern coasts and south on the eastern coast as far as Flinders Island in Tasmania, as well as Lord Howe Island and Norfolk Island in the Tasman Sea. It is also found off the Indian Ocean islands of Socotra, Seychelles, Madagascar, the western  Mascarenes. Habitat and biology. "Plectorhinchus gibbosus" occurs at depths of in coastal reefs, over sandbanks, and in the vicinity of estuaries and will enter freshwater. The small juveniles are found along sheltered sandy shorelines where they float on their sides camouflaged as fallen leafs. The adults prefer waters protected by inshore reefs but can also be found offshore in deep water, frequently recorded forming in small aggregations. In captivity they are known to eat crustaceans and other invertebrates and fish. It is an oviparous species which spawns as distinct pairs. Systematics. "Plectorhinchus ceylonensis" was first formally described in 1802 as  Holocentrus gibbosus by the French naturalist and politician Bernard Germain de Lacépède with the type locality being given as Surinam, erroneously, but is probably Indonesia. The specific name means "humpbacked", a reference to the high body which has a convex dorsal profile. Utilisation. "Plectorhinchus gibbosus" is caught using handlines and spear with the catch being sold fresh, although a small amount is preserved by salting. It is a highly regarded food fish.
