وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 12 - 13; الأشعة الظهرية الناعمة (المجموع) : 7 - 10; شوكة شرجية: 3; أشعه شرجية لينه: 4 - 6; فقرات: 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).
