Short description

Dorsal spines (total): 0; Anal spines: 0; Vertebrae: 125 - 161. A narrow-headed, big-eyed small seven-gilled shark (Ref. 247). Body fusiform and slender; dorsal fin small, originating over inner margins of pelvic fins; anal fin small (Ref. 6871). Teeth wide, low and comb-shaped (Ref. 6871). Brownish grey above, paler below, sometimes with indistinct dark blotches on body; juveniles with dark-tipped dorsal and caudal fins, adults with light fin margins (Ref. 5578, 6574, 6871). Live specimens with fluorescent green eyes (Ref. 6871).

Found on the outer continental and insular shelves and upper slopes in depths of 100 to 400 (Ref. 13573, 11230), also inshore and down to 1,000 m (Ref. 6871, 11230). Feeds on small sharks and rays, small bony fish, shrimps, crabs, lobsters, squid, and cuttlefish (Ref. 5578). Ovoviviparous (Ref. 205), with 9-12 young born per litter (Ref. 247). Very active and aggressive when captured and quick to bite but too small to be very dangerous to people (Ref. 247). Liver utilized as a source of oil. Maximum length may reach 214 cm, but this is uncertain.
