Ökologie
seewasser bathypelagisch; ozeanodrom (Ref. 51243); tiefenbereich 0 - 2400 m (Ref. 37039). Deep-water; 62°N - 32°S, 98°W - 154°W
Atlantic Ocean: North Atlantic to about 62°N, western South Atlantic to 32°S (in the eastern central Atlantic, from 30°N to about 11°S; not known from the Gulf of Guinea (5°N to 10°S) but probably inhabits all other oceanic areas). Elsewhere, Indian and Pacific oceans.
Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 17.0 cm SL Männchen/unbestimmt; (Ref. 4465)
Rückenflossenweichstrahlen (insgesamt) : 15 - 17; Afterflossenweichstrahlen: 16 - 19. Moderately elongate and slender. Maxillary teeth are comblike, closely spaced. Serial photophores are not broken into small groups. Luminous patches are lacking from the top of head and body (Ref. 37039). Barbel longer than the head, terminal expanded, ventral half of the bulb is darkly pigmented (Ref. 37473). Body black (Ref. 37039).
Body shape (shape guide): elongated.
An oceanic and mesopelagic species usually found deeper than 500 m during the day (Ref. 2802). Epi- and bathy-benthopelagic at 58-1900 m to 3200 m fishing depths (Ref. 58302). Feeds on midwater fishes and crustaceans (Ref. 2802).
