Morphology | Morphometrics
soft rays: 6. This species is distinguished from its congeners by the following combination of characters: D XIII, 10 (rarely XIII, 11); pectoral-fin rays 17-19 (modally 18); scales below lateral line 11-15 (13); body depth at anal-fin origin 26.0-32.8 (mean 30.2) % SL; head width 12.6-15.6 (14.4) % SL; postorbital length 15.4-20.0 (18.1) % SL; longest dorsal-fin spine length 42.9-51.7 (47.8) % SL; caudal-peduncle depth 9.9-11.9 (11.0) % SL; pectoral fin with 14-28 relatively large (subequal to pupil diameter) black blotches on membrane, several bands on the posterior portion of rays (not attached to membrane); several narrow to wide vertical bands laterally on body and caudal peduncle; the area of ctenoid scales on body is relatively small (usually dorsolateral region only at ca. 90 mm SL, sometimes extending below lateral line onto ventrolateral region, and on pectoral-fin base and laterally on caudal peduncle in adults greater than 80 mm SL (Ref. 101439).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00450 - 0.02327), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100) .
