Indo-Pacific: St. Paul and Amsterdam islands in the Indian Ocean, southern Australia, including Tasmania, and New Zealand. Southwest Atlantic: southern South America.
Length at first maturity / サイズ / 重さ / 年齢
成熟: Lm 30.0, range 25 - 35 cm
Max length : 70.0 cm TL オス/雌雄の選別がない; (Ref. 9563); common length : 35.0 cm TL オス/雌雄の選別がない; (Ref. 3243); 最大公表体重: 2.9 kg (Ref. 6390); 最大記録サイズ: 50 年 (Ref. 26998)
背面の脊椎 (合計) : 17 - 18; 背鰭 (合計) : 25 - 28; 肛門の骨: 3; 臀鰭: 14 - 15; 脊つい: 35. Adults have elongate upper pectoral-fin rays and are silvery with a broad black band from the nape to the pectoral-fin base (Ref. 33616).
Body shape (shape guide): fusiform / normal.
Adults demersal on the continental shelf and upper slope (Ref. 9563) to depths of 450 m (Ref. 33616). Juveniles tend to live near shallow reefs (Ref. 6390). Postlarvae inhabit offshore waters and are found in surface waters at night (Ref. 9072). Average weight is 1800 g. Feed on polychaete worms, crustaceans, mollusks and echinoderms (Ref. 28626). Flesh is quite good eating. Often sold as tiki fillets.

Jackass morwong have an extended pelagic postlarval stage (Ref. 6390). Research in New Zealand has shown that metamorphosis to the juvenile stage occurs between 9 and 12 months after hatching (Ref. 28625).
