A common deepwater dogfish of the outer continental shelves and upper slopes, commonest below 200 m ; usually benthic and epibenthic at depths from 50-1440 m with most records from 200-600 m (Compagno, pers. comm. 07/07). Solitary . Adults feed mainly on bony fishes such as hake, epigonids, lanternfish, herring, smelts, cods, rattails, squid and crustaceans. Males mature at about 105-118 cm TL . Ovoviviparous . This species is fished in Eastern Atlantic by bottom trawls, long lines, fixed bottom nets, hook and line and pelagic trawls; caught and discarded, or utilised from by-catch fisheries (IUCN discussion 07/07).
