Biologi     Ordlista (t.ex. epibenthic)

High-oceanic and bathypelagic (Ref. 6604). Adults usually found below about 1,000 m, but juveniles found between 500-800 m. No evidence of vertical migration (Ref. 6604). Feed mainly on small crustaceans. Sexually mature from about 15.2 cm (Ref. 4525). Oviparous, with planktonic larvae (Ref. 36062).
