Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 11 - 13; Vertebrae: 36 - 38. This species is distinguished from its congeners by the following set of characters: presence of a conspicuous midlateral stripe; midlateral stripe diffuse narrow or broad, straight band of dark pigmentation passing from the caudal blotch to midbody or extending to the opercle; strongly demarcated and distinctively club-shaped anteriorly; presence of an anterior extension of the club-shaped midlateral stripe in males; absence of humeral spot; 21-23 lateral line scales; caudal peduncle depth 9.0-10.6% of SL; absence of an anterior extension of a club-shaped midlateral stripe in males; absence of a humeral spot; pored lateral line scales 21-23; presence of a dark club-shaped midlateral stripe; and absence of dark blotches (Ref. 131251).
Body shape (shape guide): fusiform / normal; Cross section: compressed.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00491 - 0.02339), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
