Originally, the name barramundi referred to Scleropages leichardti and Scleropages jardinii. Body elongate; mouth large, slightly oblique, upper jaw extending behind the eye.

Found in coastal waters, estuaries and lagoons, in clear to turbid water. A species of catadromous fish, inhabiting rivers before returning to the estuaries to spawn. A protandrous hermaphrodite. Most barramundi mature first as males and function as males for one or more spawning seasons before undergoing sex inversion. A few females will develop directly from immature fish. Similarly, some males may never undergo sex inversion. Larvae and young juveniles live in brackish temporary swamps associated with estuaries, and older juveniles inhabit the upper reaches of rivers. Feed on fishes and crustaceans. Juveniles also eat insects. A very popular and sought-after fish of very considerable economic importance. Presently used for aquaculture in Thailand, Indonesia and Australia. Australia's most important commercial fish and one of the most popular angling species.
