Western Atlantic: Nova Scotia, Canada to Venezuela. Eastern Atlantic: Iceland (Ref. 12462) and Norway to the Mediterranean and the Gulf of Guinea, including Madeira, the Azores, and the Canary Islands; also Walvis Bay, Namibia to Natal, South Africa (Ref. 4313).
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 32.0 range ? - ? cm
Max length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 89108); common length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 4510); 最大體重: 1.6 kg (Ref. 40637); 最大年齡: 43 年 (Ref. 41452)
背棘 (總數): 12; 背的軟條 (總數): 12-13; 臀棘 3; 臀鰭軟條: 5. Pinkish with faint dusky bars; Y-shaped dark bar between soft dorsal and anal fins (Ref. 4313).
Adults are found in soft bottom areas of the continental shelf and upper slope. They feed on both benthic and pelagic organisms (crustaceans, fishes, cephalopods, and echinoderms) (Ref. 4570). The reproductive mode is a zygoparous form of oviparity, intermediate between oviparity and viviparity (Ref. 36265, 79712). Larvae and juveniles are pelagic (Ref. 4570). Anterolateral glandular grooves with venom gland (Ref. 57406). Sold fresh (Ref. 27121).
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
The reproductive mode is a zygoparous form of oviparity, intermediate between oviparity and viviparity (Ref. 36265, 79712). Eggs covered with gelatinous material are fertilised in the ovary. Eggs are released into the seabed at various stages of development and larvae assumes a planktonic existence once the gelatinous covering dissolves (Ref. 31150).
