Circumglobal: Except the North Pacific north of 10°N. Reported from the Walvis Ridge and near the Discovery and Meteor seamounts (Ref. 44938).
Length at first maturity / आकार / वज़न / Age
Maturity: Lm 42.0, range 41 - 43 cm
Max length : 75.0 cm SL पुल्लिंग / अलिंग; (Ref. 5208); अधिकतम प्रकाशित वज़न: 3.3 kg (Ref. 128737); अधिकतम प्रकाशित वज़न: 3.3 kg; अधिकतम सूचित उम्र: 44 वर्षो (Ref. 128738)

Found on the continental slope and upper rise (Ref. 6606). Epibenthic (Ref. 58426) and benthopelagic (Ref. 5951). Deep waters to 3277 m (Ref. 58426). May move offshore with age and spawn in the deep parts of its range. Off the eastern coast of United States, it is speculated that the population use the area only as feeding grounds with spawning taking place to the north. Feed on benthic invertebrates (Ref. 9319). Maximum weight of female from Ref. 128738.
