Espinhos dorsais (total) : 5 - 7; Raios dorsais moles (total) : 31 - 35; Raios anais moles: 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).
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.
