Characterised by its deep, pinkish-red body and steeply sloped head, it thrives in the Indo-Pacific region, especially near northern Australia. This species is prized for its quality as a food fish and is targeted by both commercial and recreational fisheries. Juveniles prefer shallow, muddy habitats, while adults venture into deeper silty waters and reefs. Known for a long lifespan of up to 42 years, this species is a cornerstone of sustainable fishing efforts
