The greenback flounder is a right-eyed flatfish of the family Pleuronectidae from the temperate coastal waters of southern Australia and New Zealand. The species reaches about 45 cm; both eyes lie on the right side and the eyed side is greenish to brown, providing camouflage on the bottom. It is common on silty sand bottoms of estuaries and inshore waters to about 100 m deep; juveniles occasionally enter rivers. The diet consists of small bottom invertebrates such as worms, crustaceans and molluscs. The species is regularly eaten and of local commercial importance.
