Comments: Found on the upper continental slope and outermost shelf.  The expanded branchial region of this shark suggests that they are adapted to bottom areas with low dissolved oxygen levels.  With little information available, reproductive mode could either be ovoviviparous (Ref. 244, 53776) or oviparous, paired eggs are laid (Ref. 50449).
