Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 9; Rayons mous anaux: 36 - 40; Vertèbres: 82 - 88. This moderately elongate species is distinguished by the following: body depth 13-16 times in SL; dorsal-fin origin clearly before midline of horizontal distance between origins of pelvic (ventral) and anal fins (V-A), origins of pelvic and dorsal fins (V–D) 32.5-43.1% V–A; A 36-40; vertebrae: prehaemal 30-32, prepelvic 30-33, predorsal 36-40, preanal 48-51, caudal 52-58; and total 82-88; total lateral-line scales 66-72; with a narrow band of black chromatophores along lower portion of abdominal ridge (Ref. 121637).
Cross section: compressed.
Mesopelagic species (Ref. 7300, 75154). Feeds on small fishes rather than shrimps (Ref. 121637).
