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 / Size / Weight / Age

Maturity: Lm 30.0, range 25 - 35 cm
Max length : 70.0 cm TL male/unsexed; (Ref. 9563); common length : 35.0 cm TL male/unsexed; (Ref. 3243); max. published weight: 2.9 kg (Ref. 6390); max. reported age: 50 years (Ref. 26998)

Short description Morphology | Morphometrics

Dorsal spines (total): 17 - 18; Dorsal soft rays (total): 25-28; Anal spines: 3; Anal soft rays: 14 - 15; Vertebrae: 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).

Biology     Glossary (e.g. epibenthic)

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.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
