Morfologia | Morfometria
This species of the ‘mitsukurii group’ is large and is distinguished by the following set of characters: body moderately robust, trunk depth 10.4-13.8% TL (mean 11.7% TL, n=9); snout is broadly triangular, with mouth width 1.72-2.48 (2.07) times the horizontal prenarial length; pre-first dorsal length 29.2-31.8 (30.2)% TL; pre-second dorsal length 60.7-63.6 (61.7)% TL; interdorsal space 23.7-27.5 (24.9)% TL; low raked dorsal fins; second dorsal-fin length 10.9-12.2 (11.6)% TL, height 3.4-4.0 (3.7)% TL, inner margin length 3.9-5.0 (4.4)% TL; second dorsal-fin base 15.1-20.0 (17.2) times the base of second dorsal spine; pre-pectoral length 21.1-24.3 (22.2)% TL; pelvic-caudal space 21.8-25.0 (23.5)% TL; caudal bar is almost upright, extending broadly from the caudal fork up the poster or margin of the upper lobe for 0.6-0.7 of its length in immature individuals, upper caudal fringe forming a narrow saddle along midlength of lobe; flank denticles tricuspid; monospondylous centra 43-46, precaudal centra 84-86, total centra 111-115 (Ref. 58441).
