简单描述
型态特徵 | 形态测量图
背棘 (总数): 2; 臀棘 0. Snout short, narrow, bluntly pointed; terminal snout scute developed but not conspicuously; suborbital ridge low; underside of snout, most of the suborbital region, and anterior half of mandible without scales; cephalic pores of the lateralis system prominent. Pyloric caeca 24 to 58. Body scales densely covered with conical to narrowly lanceolate spinules in short, slightly convergent rows. Overall color is swarthy, blackish ventrally, with bluish tinge on abdominal region; oral and branchial cavities generally pale with some blackish areas; fins dusky to blackish, first dorsal fin slightly paler basally.
吻短的，狭窄的，和顿尖的; 末端的吻鳞甲发展了但是不明显的; 眶下骨脊低的; 吻部下面, 大部分的眶下区域 , 与前半部的下颚没有鳞片; 侧线系统的头部孔突出的。 幽门盲囊 24 到 58. 身体鳞片厚密地覆盖着了锥形对在短又些微趋集于一点的列中狭窄矛尖形的小刺。 整体的色彩是黑黝黝的, 黑色的腹地, 藉由在腹部的区域上的蓝色的淡色; 口腔与鳃室通常灰白的有一些黑色的区域; 鳍暗色的到黑色的, 第一背鳍些微较灰白基部地。
Food items are generally forcibly regurgitated by the fish's expunging gas bladder as it is hauled from the depths, but fish remains have been caught inside the mouth of a few individuals. Considered opportunistic feeders and will eat whatever animal food they encounter in the natural habitat as long as it is of appropriate size (Ref. 4525).
食物组成通常是当它被拖网从深度，一定反胃藉由鱼的爆裂的气鳔, 但是鱼残余物曾经捕捉一些个体的嘴巴内。 被认为是随机捕食者而且将吃他们在自然栖息地见到只要它是有适当大小的任何的动物食物.(参考文献 4525)
