An uncommon primitive shark (Ref. 26346) found on outer continental and insular shelves and upper slopes, usually between 120 and 1,280 m but occasionally caught at the surface (Ref. 247). Feeds on other sharks, squid and bony fish (Ref. 26346). Ovoviviparous (Ref. 50449), litter size ranges from 2 to 10 (Ref. 37390). Not dangerous but teeth are sharp enough to inflict lacerations on the hands of the unwary scientist examining its mouth (Ref. 247). Incidental in bottom trawl catches and utilized as fishmeal and as food fish (Ref. 247).
