背棘 (总数): 7; 背的软条 (总数): 10; 臀棘 1; 臀鳍软条: 10. This species is characterized by the following; females with closely-set, slightly flexible tricuspid premaxillary teeth and 0-1 canine-like tooth at the posterior tip of the premaxilla; immature males with conical teeth posterior to tricuspid teeth; adult males with only fixed recurved conical to canine-like teeth; scales are much higher than long, along lateral midline between second dorsal and anal fins; few ctenoid scales midlaterally in males while only cycloid scales in females, and female scales are generally smaller than in males (Ref. 75882).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
