Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Diagnosis: small, closely-packed teeth; relatively small maximum size; larger specimens often with bright greenish metallic iridescence on upper surface of the body, mature males can be more bluish-grey (Ref. 55949).
Found in reedy bays and lagoons, at open sandy beaches, throughout the shelf and reef zones (Ref. 55949), and in the open water (Ref. 5595, 55949). Piscivorous (Ref. 5595, 55949). Small specimens mostly feed on crustacean zooplankton, adults predominantly eat larvae and juveniles of small shoaling zooplanktivorous cyprinid Engraulicypris sardella; female mouthbrooder (Ref. 55949).
