Author: (Linnaeus, 1758)
FBname: Angular roughshark
Comments: Found on the outer continental shelf and upper slope (Ref. 5578).  Depth range from 60-660 m (Ref. 247) and from 549-777 m in the eastern Ionian Sea (Ref. 56504), and 818-1309 m NW Africa (Ref. 128029).  Feeds on polychaetes (Ref. 247) and sipunculids (apparenly  a suction feeder which mainly feeds on worm-like prey), which are rapidly digested, and the rapid gastric evacuation could partially explain the vacuity of several guts; teleosts, crustaceans and echinoderms are considered as accessory prey items, thus recorded predation on egg cases of the smallspotted catshark <i>Scyliorhinus canicula</i> remains an occasional phenomenon (Ref. 81816).  Ovoviviparous (Ref. 205).  Utilized for fishmeal, oil, and smoked and dried salted for human consumption (Ref. 247).
