Info

Argyrosomus japonicus is a large, silvery to greenish-bronze fish with a moderately elongated body, a concave to pointed caudal fin, and pearly white spots along the lateral line.
Small juveniles live in estuaries and nearshore waters. Adults and subadults are found along surf beaches, around rocky headlands, and in deeper areas offshore.
Individuals congregate into schools in the lower portions of estuaries and near river mouths during high tide.
The species makes seasonal migrations along the coast and in and out of estuaries.

Upper surface grayish green to steel blue, underside silver-gray, with darker oblique bands following scale rows in small individuals; inner surface of mouth and opercula bright orange; fins slightly yellowish; conspicuous black spot at base of each pectoral fin.

The common name "Mulloway!" is an Aboriginal word meaning "the largest.
Other common names derive from the term "jewfish," which refers to the very large otoliths or ear bones of the mulloway collected for use as jewelry.

Etymology
The specific name "japonicus "refers to where the species was found: near Nagasaki, Japan.
