Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Tia mềm vây hậu môn: 24 - 27; Động vật có xương sống: 75 - 82. This species is distinguished by the following characters: A 24-27, its origin at the hindmost fifth of SL; pectoral fin rays 10-11; origins of pelvic fins distinctly in front of a vertical from first dorsal fin ray; conspicuously modified lateral line; dorsal and ventral protrusions of each lateral line scale extend to dorsal and ventral midline, forming a transverse striation of the body; elongated and subcylindrical body; snout pointed and terminal, the upper jaw extending just below nasal aperture; base of adipose long (at least twice the height of the caudal peduncle); total vertebrae 75-82 (Ref. 88797).
Juveniles taken at 45 m; adults from 550 to more than 2, 000 m. Feeds on krill and fishes.
