Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 10 - 11; Rayons mous anaux: 8 - 9; Vertèbres: 46 - 47. Body deep. Short pectoral fins, long ventral fins. Relatively large head and absence of ventral light organs. Line of dark chromatophores along the body below lateral line (Ref. 37473).
Body shape (shape guide): elongated.
Oceanic and mesopelagic species (Ref. 6686). Taken regularly at depths shallower than 458 m, with scientific deep-sea fishing gear. Feed mainly on small crustaceans, particularly copepods (Ref. 4525). Oviparous, with planktonic larvae (Ref. 35626) and eggs (Ref. 6686). Paedomorphic (Ref. 35626).
