Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 8; Spine anali: 1; Raggi anali molli: 8.

Found both upstream and in estuaries. Carnivorous. Spawning season from July to October. Eggs are laid under stones in river shoals. Larvae travel in both river and the sea, and return to rivers from September to November. Caught by small trap nets in rivers, but not in abundance.
