प्रथम परिपक्वता पर लंबाई / आकार / वज़न / आयु
परिपक्व अवधि: Lm 293.0, range 264 - 322 cm
Max length : 617 cm TL पुल्लिंग / अलिंग; (Ref. 83323); common length : 200 cm TL पुल्लिंग / अलिंग; (Ref. 5217)
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; गुदा कांटा: 0. Flat, bladelike, elongated snout, tiny eyes without nictitating eyelids, soft, flabby body, slender, very long cusped teeth in long, protrusible jaws, long caudal fin without a ventral lobe (Ref. 247). Pinkish-white with bluish fins, becoming brownish grey after death (Ref. 5578, 11228).
Body shape (shape guide): elongated.
Found on outer continental shelves and upper slopes, but rarely in shallow water close inshore (Ref. 247, 43278). Jaws are highly specialized for rapid projection from the head to snap up small animals (Ref. 247). Feeds on jacopever, pelagic octopus and crabs (Ref. 5578). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Probably slow-moving and neutrally buoyant (Ref. 6871). Utilized dried salted (Ref. 247)

Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 247, 50449). Distinct pairing with embrace (Ref. 205).
