簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 臀棘: 0. Head large; eyes large; snout moderately pointed, its anterolateral margin incompletely supported by bone. Head ridges rather weakly scaled, other head scales mostly without spinules; the dorsal and ventral snout surfaces mostly naked. Spines on lower jaw and pectoral girdle without spinules. Light organ large, lens-shaped black fossa between the pelvic fin bases. Swim bladder oval, with 6 to 11 short retia mirabilia and gas glands. Pyloric caeca 10 to 14. Overall color is light brown to swarthy, somewhat silvery ventrally, with heavy punctuations; mouth pale, blackish along tongue base; gill cavity blackish, paler with punctuations toward inner surfaces.
頭部大的; 眼大的; 吻一般尖, 它的前外側邊緣不完全地由硬骨支撐了。 頭部脊相當弱的覆有鱗片的, 其他的頭部鱗片大部份沒有小刺; 背部與腹的吻表面大部份裸露。 沒有小刺的在下頜與肩帶上的棘。 發光器大的, 晶狀體-在腹鰭基底之間的形狀黑色的窩。 泳鰾橢圓形,6 到 11 短的 retia mirabilia 與氣腺。 幽門盲囊 10 到 14. 整體的色彩是淡褐色到黑黝黝的, 略微銀色的腹地, 有茂盛的標點; 嘴灰白的, 黑色的沿著舌基底; 鰓腔黑色的, 用對於內面的標點灰白。
Juveniles are bathypelagic (Ref. 9315). Feeds mainly on copepods and other small crustaceans, but not exclusively bottom-dwelling invertebrates (Ref. 9315).
稚魚是深海區的。 (參考文獻 9315) 主要吃橈腳類的動物與其他的小型甲殼動物, 但是不專門地底棲無脊椎動物.(參考文獻 9315)
