Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 13 - 14; Raggi dorsali molli (totale) : 10; Spine anali: 7; Raggi anali molli: 9 - 10; Vertebre: 23. Coloration highly variable; influenced by substrate's color and mood of the fish. Upper greenish to sandy brown, paler below. Color patterns extend to the fins. Spines slender, pungent and venomous. Preopercular angle 88°-98°; cheeks with few scales; midline of thorax without scales between pelvic ridges. Long flap of anterior nostril shortens with increasing age.
Inhabits inshore areas and inner reefs (Ref. 9710). Often occurs among seagrasses to browse on 'aufwuchs'. Forms schools. A food fish that is occasionally poisonous (Ref. 4537).
