臀鳍软条: 8 - 11. Distinguished from its congeners by possessing large coronomeckelian bone and dentigerous arm of premaxilla about 1.5 times the height of ascending process (vs. small coronomeckelian bone and dentigerous arm of premaxilla about 2 times or more the height of ascending process), and the following combination of characters: quadrate-mandibular articulation at anterior half of orbit; mouth hypognathous; posterior border of maxilla at anterior border of orbit or placed anterior to it, generally not beyond posterior border of lachrymal; hyoid artery piercing dorsal hypohyal; 3 predorsal bones; one super-numerary spine on first dorsal pterygiophore (rarely none); 3rd or 4th dorsal fin spine the longest; 7-8 trisegmented pterygiophores in dorsal fin; upper jaw length 90-120% snout length and 28-36% HL; head length 24-33% SL; length of pectoral and pelvic fins 48-75% HL; 50-80% body depth; 14-17 pectoral fin rays; 8-11 anal fin rays; 45-49 caudal fin rays; procurrent spur present (Ref. 55324).
与它的同类区分藉由持有大的 coronomeckelian 硬骨与前颌骨的有齿手臂大约 1.5 倍于高度向上突起 (vs. 小的 coronomeckelian 硬骨与前颌骨的有齿手臂大约两倍或更多高度向上突起), 与下列的组合特徵: 在前半部的眼窝方骨-颚骨的关节; 嘴 hypognathous; 在眼窝的前缘颚骨的后缘或放置位于它前, 通常不超过泪骨的后缘; U 字形的动脉刺骨的背部 hypohyal; 3个前背骨; 在第一背鳍支鳍骨上的一根超级-数目的棘;(很少地没有) 第三或第 4根背鳍棘最长的; 在背鳍的 7-8 trisegmented 支鳍骨; 上颌长度 90-120% 吻的长度与 28-36% HL; 头长 24-33% SL; 胸鳍与腹鳍 48-75% HL 的长度; 50-80% 体高; 14-17个胸鳍鳍条; 8-11个臀鳍棘条; 45-49个尾鳍鳍条; 前流的马刺呈现。 (参考文献 55324)

50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00400 - 0.02738), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.3 ±0.1 se; based on diet studies.
回复力 (Ref.

Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
Nutrients (Ref.
