Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 27 - 31; Spine anali: 0; Raggi anali molli: 26 - 30. Nodular luminous organ present sporadically on body; no luminous organ on shoulder (Ref. 13608).
Usually found near continental slopes (Ref. 4736). Bathypelagic (Ref. 58426). Feeds primarily on crustaceans (euphausiids, copepods, amphipods and decapod zoea), also ostracods and small cephalopods (Ref. 4736).
