Maxilla short, only reaching to front border of pre-operculum; first supra-maxilla about two thirds of second. No dark blotches on nape or behind upper part of gill opening.
Body shape (shape guide): elongated; Cross section: compressed.
Adults inhabit streams and associated lagoons, in clear or turbid water; also in brackish estuaries (Ref. 44894), in main river channels as well as smaller tributaries (Ref. 2847). A riverine species reaching nearly 900 km up the Fly River, but also down to the estuary. They form shoals in deeper water of lagoons. Breeding biology is poorly understood, but it seems likely that spawning takes place in fresh water as juveniles have been collected from the upper reaches of some Queensland rivers. The diet consists of small crustaceans, fishes, insects and some plant material (Ref. 44894). Piscivorous (at least as large adults), recorded as feeding on Clupeoides papuensis and Melanotaenia nigra in the Fly River. The only anchovy that is restricted to mainly freshwater habitats (Ref. 44894). The largest anchovy known so far.
