简单描述
型态特徵 | 形态测量图
背棘 (总数): 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.
头部大的; 眼大的; 吻一般尖, 它的前外侧边缘不完全地由硬骨支撑了。 头部脊相当弱的覆有鳞片的, 其他的头部鳞片大部份没有小刺; 背部与腹的吻表面大部份裸露。 没有小刺的在下颌与肩带上的棘。 发光器大的, 晶状体-在腹鳍基底之间的形状黑色的窝。 泳鳔椭圆形,6 到 11 短的 retia mirabilia 与气腺。 幽门盲囊 10 到 14. 整体的色彩是淡褐色到黑黝黝的, 略微银色的腹地, 有茂盛的标点; 嘴灰白的, 黑色的沿着舌基底; 鳃腔黑色的, 用对于内面的标点灰白。
Juveniles are bathypelagic (Ref. 9315). Feeds mainly on copepods and other small crustaceans, but not exclusively bottom-dwelling invertebrates (Ref. 9315).
稚鱼是深海区的。 (参考文献 9315) 主要吃桡脚类的动物与其他的小型甲壳动物, 但是不专门地底栖无脊椎动物.(参考文献 9315)
