Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 12 - 13; Radios blandos dorsales (total) : 7 - 10; Espinas anales: 3; Radios blandos anales: 4 - 6; Vértebra: 28. Lack scales (Ref. 33616).
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).
