Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 14; Anal soft rays: 17 - 19. Males with single black-bordered supracaudal gland; females with two infra-caudal luminous patches; occasional specimens with both. Luminous organs in the anal area, 5-6 anteriorly and 5-7 posteriorly, 11-13 total.

High-oceanic, mesopelagic at depths between 375-800 m during daytime and 12-200 m during night. Depth range from 0-850 m (Ref. 4479) and from 541-1085 m in the eastern Ionian Sea (Ref. 56504). Photophores present. Feeds mainly on calanoid copepods, also euphausiids and copepodites. Feeding occurs at night in Norwegian fjords (Ref. 9209) and in northwest Africa (Ref. 9194).
