soft rays: 0. A heavily-bodied, cylindrical shark with a large, long and broad snout, long nasal flaps and high, triangular, saw-edged upper teeth; interdorsal ridge high and prominent; pectoral and dorsal fins large and straight (Ref. 5578). Grayish with no conspicuous markings, white below (Ref. 5578); inner corners of pectoral fins blackish (Ref. 9997).
Found near the edge of the continental and insular shelves and uppermost slopes (Ref. 244). Rare in shallow waters (Ref. 9997), bottom associated near shelf breaks and drop-offs; young may occur at 25 m (Ref. 58302). Feeds on bony fishes, other sharks, stingrays, and cuttlefish (Ref. 244). Viviparous (Ref. 50449). Utilized for fishmeal, liver oil, and shagreen (Ref. 9997). Minimum depth reported taken from Ref. 244.
Viviparous, placental (Ref. 50449). Gives birth every second year with 1-13 (average 9)pups per litter (Ref.58048). In the Mediterranean, sharks give birth in August and September, however in Madagascar, young are born in September and October (Ref. 244).
