簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 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﹐狹窄的﹐和頓尖的; 末端的吻鱗甲發展了但是不明顯的; 眶下骨脊低的; 吻部下面, 大部分的眶下區域 , 與前半部的下顎沒有鱗片; 側線系統的頭部孔突出的。 幽門盲囊 24 到 58. 身體鱗片濃密地覆蓋著了錐形對在短又些微趨集於一點的列中狹窄矛尖形的小刺。 整體的色彩是黑黝黝的, 黑色的腹地, 藉由在腹部的區域上的藍色的淡色; 口腔與鰓室通常灰白的有一些黑色的區域; 鰭暗色的到黑色的, 第一背鰭些微較灰白基部地。
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).
食物組成通常是當它被拖網從深度，一定反胃藉由魚的爆裂的氣鰾, 但是魚殘餘物曾經捕捉一些個體的嘴巴內。 被認為是隨機捕食者而且將吃他們在自然棲息地見到只要它是有適當大小的任何的動物食物.(參考文獻 4525)
