بلوغ: Lm42.2 range ? - ? cm Max length : 125 cm TL جنس نر / بدون خواص جنسي; (Ref. 3276); 95.0 cm FL (female); common length : 90.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 3276); بيشينه وزن گزارش شده: 30.0 kg (Ref. 9988); بيشينه سن گزارش شده: 35 سال ها (Ref. 6086)
Most common around 200 m, usually over mud or sand bottom and occasionally over rough bottom (Ref. 9988); prefers temperature of 8-17°C (Ref. 5951). Feeds mainly on shrimp and crabs, but also takes fish, squid, bivalves and holothurians. Sensitive to cold water (Ref. 9988), a mass die-off occurred in 1882, after which the species was rare for decades, presumably due to unusually cold water (Ref. 7251). Marketed fresh or frozen; can be steamed, pan-fried, broiled, microwaved and baked (Ref. 9988).
