In the sub-arctic region, young may be found at depths between 50-300 m while older individuals occur at depths between 200-500 m (Ref. 6885). Further south, in the transition zone, young are found from 200-300 m and older individuals between 200-500 m (Ref. 6885). Oviparous, with planktonic larvae and eggs (Ref. 36655).
