Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 12 - 13; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 11 - 13; Động vật có xương sống: 45 - 46. Chin barbel half as long as the head and bears a small explanate bulb lacking appendages. Base of anal fin significantly behind the vertical of the dorsal fin end. Postorbital organ large and angled at 20°-30° with respect to the longitudinal body axis. It extends behind the vertical of the back side of the orbit and is covered from above with a pigmented fold of skin. Bunch-like aggregation of luminous spots proceeds down and to the rear from the back tip of the postorbital organ. Numerous spots of luminous tissue on head, the gill cover, back of the head, around the chin area, on the jaws, as well as on the front side of the body, behind the head, and above and below the lateral row of photophores. Serial photophores are not large and form no clear bends or steps (Ref. 30704).
Body shape (shape guide): elongated.
