Short description
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 9; Radios blandos anales: 41 - 43; Vértebra: 94 - 98. This species is distinguished by the following characters: a relatively slender body, its body depth 15-19 times in SL; dorsal-fin origin at about midline of distance between the origins of pelvic and anal fins (V-A), the distance between the origins of pelvic and dorsal fins (V-D) 46.8-55.0% of V–A; pelvic-fin origin (VFO) at or slightly behind the midline of the fish, the prepelvic length 50.6-53.2% SL; vertebrae: prehaemal 32-35, prepelvic 33-35, preanal 53-57, caudal 60-66, total 94-98; lateral-line scales 75-81; the abdomen ridge with broad black margin (Ref. 121637).
Collected by midwater trawl from surface to 532 meters, suggesting that it is a mesopelagic species that may have diurnal vertical migration. Stomach contents have myctophids or other pelagic fishes such as Bregmaceros spp. rather than sakura shrimps (Lucensosergia lucens) (Ref. 121637).
