Body slender and elongate; vent midway between origins of pelvic and anal fins (Ref. 27437). Posterior margin of caudal fin deeply indented (Ref. 6885).

头部棘弱的 - 鼻骨, preocular, 眶后的,鼓皮似的与腔壁的棘存在的,眶上的, 冠与颈背的棘不存在.(参考文献 27437) 身体细长的与延长; 在腹鳍与臀鳍的起源之间的排泄孔中途.(参考文献 27437) 尾鳍后缘深深地切割成锯齿状。 (参考文献 6885) 呈绿色的粉红色背面, 腹地褪成光.(参考文献 27437) 鳃条骨: 7.(参考文献 36715)
Found in a wide range of habitats, sometimes in large schools well offshore and off bottom (Ref. 2850). Juveniles are pelagic (Ref. 36715). Adults feed on planktonic animals, mainly krill (Ref. 2850). Viviparous, with planktonic larvae (Ref. 36715). A very important prey species for predatory fishes and marine mammals (Ref. 2850). Not marketed due to its small size (Ref. 2850).
