背棘 (總數) : 17 - 18; 背的軟條 (總數) : 25 - 28; 臀棘: 3; 臀鰭軟條: 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).
成魚有細長的上面胸鰭鰭條與是銀色的有一個寬的黑色條紋從後頸到胸鰭基底.(參考文獻 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.
成魚棲息於大陸棚與上層斜坡 (參考文獻 9563) 到深度 450 公尺。 (參考文獻 33616) 稚魚傾向生活在淺水礁區附近。 (參考文獻 6390) 後期幼體居住於離岸水域而且被發現於水表面在晚上。 (參考文獻 9072) 平均的重量是 1800 g 。 捕食多毛類的蠕蟲，甲殼動物，軟體動物與棘皮動物。 (參考文獻 28626) 肉是相當好的吃。 時常賣作. tiki 魚排。
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。
