簡短描述
型態特徵 | 形態測量圖
This moderate-sized species of the ‘mitsukurii group’ has the following set of characters: moderately elongate body, depth 9.9-11.5% TL; narrowly triangular snout, moderately long, preoral length 2.0-2.44 times the horizontal prenarial length, 10.3-10.8% TL, mouth width 1.56-1.81 (1.73) times the horizontal prenarial length; pre-first dorsal length 27.7-30.0 (28.5)% TL; pre-second dorsal length 60.2-62.9 (61.3)% TL; interdorsal space 23.5-25.6 (24.7)% TL; weakly bifurcated anterior nasal flap; first dorsal fin large, upright, first dorsal-fin height 7.0-8.0% TL; first dorsal-fin spine strong, upright and broad-based; second dorsal-fin spine long, moderately broad-based; prepectoral length 21.9-23.1 (22.6)% TL; pelvic-caudal space 25.0-26.7 (25.9)% TL; pectoral fin of adult individuals not falcate; pectoral-fin inner margin relatively short, 6.4-7.1% TL; caudal bar is oblique, extending along base of lower lobe to caudal fork, less than 0.1-0.2 of posterior margin of upper lobe, upper caudal fringe narrow, with a large dark saddle, distinctly closer to tip of lobe than its base; flank denticles are strongly tricuspidate; monospondylous centra 43-44, precaudal centra 86-91, total centra 1130-120 (Ref. 58442).
Commonly caught by demersal longline fisheries operating in deepwater; utilized for its meat, fins and liver oil which is of high value (Ref. 58048).
