簡短描述
檢索表 | 型態特徵 | 形態測量圖
Body large, robust; either partially scaled or naked body. Broad, angular posterior nostril flap, with flap and nostril rim ornamented with numerous leaf-like marginal projections. Very oblique gill slits (ca 30° relative to horizontal axis of the body).
身體大的, 結實的; 或部份地覆有鱗片的或裸露的身體。 寬又有角的後鼻孔蓋,與鰓蓋與鼻孔邊緣裝飾了有很多的葉狀邊緣的突出。 非常斜的鰓縫 (ca 30個 ° 身體的相對於水平軸).
Found on the lower continental slope at 1,465-2,070 m (Ref. 6726). Carnivorous, feeding primarily on galatheid crustaceans (Ref. 6726). Probably spawn in June-July (Ref. 6726).
