Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 17 - 18; членистые (мягкие) лучи спинного плавника (общее число) : 25 - 28; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 14 - 15; позвонки: 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).
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).
