Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 0; Espinas anales 0; Radios blandos anales: 0. A cylindrical, dwarf dogfish shark with a long bulbous snout, small round eyes, and small gill slits; caudal fin paddle-shaped (Ref. 5578). Dark brown with conspicuous light-edged fins (Ref. 5578). Ventral surface covered with minute photophores (Ref. 6577).

Probably oceanic (Ref. 5578). The holotype was caught off a beach, but a second specimen was taken in the Atlantic at night between the surface and 502 m (Ref. 247). Food unknown but may subsist on pelagic fish and invertebrates (Ref. 247). Probably ovoviviparous with very few young (Ref. 247).
