簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 158 - 162. Body uniformly grayish or brown to nearly black. Dorsal fin origin well behind pectoral fin tips; pectoral fin rounded, not elongate and well-developed. Posterior nostril a hole above the upper lip, covered by a flap that extends to or below the edge of the mouth. Upper lip lacks barbels between anterior and posterior nostrils. Pores small but conspicuous, SO 1 + 4, IO 4 + 2, POM 6 +2. Teeth small and conical, biserial on anterior vomer and jaws (Ref. 40865).
身體均勻淺灰色或褐色到幾乎黑色。 背鰭起點在胸鰭頂端正後方; 胸鰭圓形的, 不延長與發展良好的。 後鼻孔在上嘴唇上面的一個洞, 被一個延伸到的鰓蓋蓋著了或在嘴巴的邊緣之下。 上嘴唇缺乏在前面與後面的鼻孔之間的觸鬚。 孔小的但是顯著的, 因此 1+4 ， IO 4+2 ， Pom 6 +2. 齒小而錐形, 雙列的在前面犛骨與顎.(參考文獻 40865)
This species is captured by trawl over sand and muddy bottom between 36-1350 and observed from submersibles to be most abundant between 250-350 m, with only the heads exposed over sandy substrates or resting on the sediment with their bodies in S-shaped curves (Ref. 86730). Mature females collected 48-62.8 cm TL (Ref. 40865).
成熟的雌性收集了 48-62.8 公分TL 。
