Biologi     Ordlista (t.ex. epibenthic)

Collection depth between 6-370 m, deepest recorded depth at 675 m. Large adults common along the edge of the continental shelf at 100-300 m where the species is targeted for commercial use. Captured in the offshore trawl fishery. Males and females captured by trawl surveys vary widely in maturity during the summer (May-July) (Ref. 53613).
