Short description Morphology | Morphometrics

This species is a moderate-sized one of the ‘mitsukurii group’ with the following set of characters: very elongate body, depth 10.1-12.6% TL; narrow, moderately long snout, preoral length 2.38-2.53 times its horizontal prenarial length, 10.5-11.3% TL, mouth width 1.54-1.77 (1.66) times its horizontal prenarial length; pre-first dorsal length is 28.9-31.3 (30.0)% TL; pre-second dorsal length is 60.2-62.7 (61.2)% TL; interdorsal space is 22.3-24.7 (23.8)% TL; dorsal fins are small, raked, first dorsal-fin height 6.3-7.2% TL; first dorsal-fin spine short and weak; second dorsal-fin spine slender with moderately broad base; prepectoral length 21.7-23.6 (22.4)% TL; pelvic-caudal space 24.0-26.5 (25.4)% TL; pectoral fin of adults slightly falcate; pectoral-fin inner margin relatively short, 7.1-7.8% TL; caudal bar almost upright, extending narrowly from the caudal fork up the posterior margin of the upper lobe for usually about 0.4 (rarely to 0.6) of its length in immature individuals, upper caudal fringe narrow, sometimes with a narrow central blotch on upper lobe; flank denticles are weakly tricuspidate; monospondylous centra 37-42, precaudal centra 80-87, total centra 105-116 (Ref. 58442 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 12.4 - 18.9, mean 15.6 (based on 46 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00339 (0.00157 - 0.00733), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  4.3   ±0.3 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  High to very high vulnerability (66 of 100) .
