简单描述 检索表 | 型态特徵 | 形态测量图

背棘 (总数) : 12; 背的软条 (总数) : 10; 臀棘: 3; 臀鳍软条: 8. This species is distinguished from its congeners by the following set of characters: scale rows above lateral line 6½; scales rows between 5th dorsal-fin spine base and lateral-line scale 5½ or 6½; pored lateral-line scales 51 or 52; suborbital depth subequal to or greater than the orbit diameter; dorsal-fin rays are reddish pink as well as similar reddish pink on upper margin dorsal-fin ray (no clear yellow or faint yellowish); body with 7 or 8 faint irregular blue spotted lines, not visible from all angles; reddish membranes on caudal-fin lobes and caudal fin with clear white lowest margin of lower caudal fin lobe; without blue iridescence on each scale of dorsal and lateral sides of whitish pink body; canines are large, both upper and lower canines on both jaws usually visible even when mouth closed; body deep 44-46% (mean 44%) of SL; anal- and pelvic- fin rays are whitish or reddish hyaline; no yellow (white) rear margin of branchiostegal rays and membrane; weak bony bulge present before and above eye, forming a low median ridge in larger specimens of over 30 cm SL; caudal fin is moderately forked (Ref. 106993).

Estimates based on models

Preferred temperature (Ref. 115969): 14.2 - 24.7, mean 20.5 (based on 105 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00609 - 0.02604), b=3.04 (2.87 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  4.1   ±0.7 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
