Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 30.0, range 25 - 35 cm
Max length : 70.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9563); common length : 35.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3243); 最大体重: 2.9 kg (Ref. 6390); 最大年龄: 50 年 (Ref. 26998)
背棘 (总数): 17 - 18; 背的软条 (总数): 25-28; 臀棘 3; 臀鳍软条: 14 - 15; 脊椎骨: 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).
成鱼有细长的上面胸鳍鳍条与是银色的有一个宽的黑色条纹从后颈到胸鳍基底.(参考文献 33616)
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.
成鱼栖息于大陆架与上层斜坡。 (参考文献 9563) 稚鱼倾向生活在浅水礁区附近。 (参考文献 6390) 后期幼体居住于离岸水域而且被发现于水表面在晚上。 (参考文献 9072) 平均的重量是 1800 g 。 捕食多毛类的蠕虫，甲壳动物，软件动物与棘皮动物。 (参考文献 28626) 肉是相当好的吃。 时常卖作了 tiki 鱼排。

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).印度-太平洋: 聖保羅與阿姆斯特丹印度洋中的島嶼，澳洲南部, 包括塔斯梅尼亞 , 與紐西蘭。 西南大西洋: 南美洲南部。
