Habitat Type: Marine

Comments: Mostly between seaward edge of continental slope and 100-fathom contour; sometimes closer to shore if there is deep water nearby (Leatherwood and Reeves 1983). In Canada, depth of water at sighting locations ranged from 10 to 2000 fathoms, with mean, median, and modal depths of 617, 400, and 100 fathoms, respectively (Stacey and Baird 1991).
