Mulloway (Jewfish)
Argyrosomus japonicus
Key differences: Mulloway generally have a more silvery body with less distinct or absent spots in adults, and a more pointed caudal fin. Juveniles may have spots, but they are typically smaller and less numerous than those on Protonibea diacanthus. The lateral line scales of Mulloway are also often more prominent.
Teraglin
Atractoscion aequidens
Key differences: Teraglin are typically more slender and silvery, lacking the prominent dark spots of the Black Jewfish. Their caudal fin is usually more forked or emarginate.
Other Croakers/Drums
Various Sciaenidae species
Key differences: Many other croakers exist, but few reach the size and possess the distinct large, dark spotting pattern of Protonibea diacanthus. Careful examination of fin ray counts, scale patterns, and overall body morphology is often required for definitive identification among smaller species.
