সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স
পৃষ্ঠীয় কাঁটা (মোট ) : 0; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 13 - 15; পায়ূ কাঁটা : 0; পায়ূর নরম পাখনা্তুন্ড: 19 - 21; কশেরুকা : 37 - 40. Adipose fin short based and slender; pectorals long, reaching beyond pelvic insertion but not reaching anus (Ref. 6885). Black dorsally, silvery on sides; dusky on bases of fins; light from photophores pale green (Ref. 6885). Branchiostegal rays: 9-10 (Ref. 31442).
Epipelagic to mesopelagic, at surface at night (Ref. 31442). Adults feed on small crustaceans (Ref. 11712). Oviparous, with planktonic eggs and larvae (Ref. 31442). Lipid content is 4.3 % in fresh body weight, while wax ester is present in trace amounts (Ref. 9197). Preyed upon by fishes, cephalopods, birds and marine mammals. Easily attracted to a light suspended above the water at night and many are captured in dipnets (Ref. 4525).
