Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 14 - 17; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 12 - 16. Black in color, pale luminous patches on middle of snout and along front of upper jaw (Ref. 3982). Pale luminous patches develop with growth on shoulder and on lower sides between pectoral and pelvic fins below dorsal (Ref. 3982). Body moderately elongate and slender, maxillary teeth comblike. Serial photophores are not broken into small groups (Ref. 37039).
Body shape (shape guide): elongated.
An oceanic and mesopelagic species usually found deeper than 500 m during the day. Feeds on midwater fishes and crustaceans. Most common species taken in surface nets at night (Ref. 2802).
