Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 12 - 13; Rayons mous dorsaux (Total) : 7 - 10; Épines anales: 3; Rayons mous anaux: 4 - 6; Vertèbres: 28. Lack scales (Ref. 33616).
Body shape (shape guide): fusiform / normal.
Occur in inshore waters (Ref. 9563). Most active at night, lying motionless during the day. Spawn during August-September and seem to be triggered by an increase in water temperature at the onset of spring. Smaller individuals feed mainly on shrimps and crabs, while bigger ones are piscivorous (Ref. 2156). Adults possess venomous infraorbital, preopercular and dorsal-fin spines (Ref. 33616).
