पृष्ठीय रीढ़ (सम्पूर्ण) : 5 - 7; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 31 - 35; ऐनल सौफट रेज़: 31 - 35. Body brownish, fins darker except first dorsal. With 4 or 5 irregular darker cross-bars, inside of mouth and branchial cavities blackish (Ref. 11892).
Body shape (shape guide): fusiform / normal.
Found more commonly at depths greater than 300 m. Adults feed on amphipods (mainly Orchomene plebs), errant polychaetes, and in lesser amounts, fishes. Isopods and other crustaceans are probably included in the diet.
