Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 15 - 16; Spine anali: 3; Raggi anali molli: 10 - 11. Distinguished by the following characteristics: two color patterns, first is brown blotched pattern, grey or greyish green with oblong dark blotches dorsally, forming an irregular maze-like, pale reticulum, second is plain colored pattern is uniform greyish brown, darker fins and edged with white; depth of body contained 2.9-3.1 times in SL; head length 2.6-2.8 times in SL; angular preopercle, with distinct serrate lobe at angle; posterior nostrils notably larger than anterior nostrils (Ref. 89707).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Occurs from mangrove area to over hard bottom of the continental shelf and the slope (Ref. 11035). According to Thomson et al. (1979, Ref. 6852), this species prefers mangrove estuaries. Adults and juveniles occur in shallow water with adults found to depths of 60 m.
