Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 10; Spine anali: 7; Raggi anali molli: 9; Vertebre: 13. Body bluish white; head brown to brownish or golden yellow with irregular blue lines. Preopercular angle 91°-102°; strong overlapping scales cover cheeks; midline of thorax scaled, not pelvic ridges. Anterior nostril with low flange, broadened slightly posteriorly. Spines stout, blunt or pungent, and venomous.

Juveniles live among mangroves then move out to lagoon and coastal reefs as they mature. Forms schools. Feeds on algae growing on seagrasses, mangrove roots and rocks. Adults congregate inshore in groups of several hundreds to spawn in summer. Spawning is by pairs; sticky eggs laid on the bottom. Its very high quality flesh commands premium prices (Ref. 9813). Adults on coastal reefs, subject to strong currents (Ref. 48637). This species can tolerate very low salinities (2 ppt) and temperatures up to 38 C (Ref. 37816).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Throughout summer, adults form inshore breeding groups of several hundred individuals on the 7th or 8th days of the lunar month; pairs break from these groups to spawn. The species has a high fecundity of 350,000/spawning season.
