生态学
海洋 深海底的; 深度上下限 0 - 1570 m (Ref. 10290), usually 120 - 1280 m (Ref. 247). 深水域; 74°N - 58°S, 169°W - 180°E (Ref. 84631)
Wide-ranging but with patchy distribution. Western Indian Ocean: off South Africa. Western Pacific: off Japan to New Zealand. Eastern Pacific: southern California, USA to northern Chile. Eastern Atlantic: northern Norway to northern Namibia, possibly the eastern Cape of Good Hope, South Africa. Three specimens have been recorded from the western Atlantic (Ref. 13608).

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).
