Morphology | Morphometrics
soft rays: 12;
Vertebrae: 26. This species is distinguished from its congeners by the following set of characters: D XIV,13-14; A II,12; pectoral rays 19-20; tubed lateral-line scales 15-17; gill rakers 5-6 + 17-20 = 22-26; caudal fin with two spinous procurrent rays dorsally and ventrally. Colour of adult generally silvery white with a large black spot on the pectoral fin base that reaches the lower limits of the axil; juvenile's head and body entirely gunmetal to silvery-grey, overlaid with greenish blue iridescence dorsally; the iris pale blue to grey, bright metallic blue on dorsal edge; axil of pectoral fin base with large black spot; caudal peduncle greyish yellow to bright yellow posteriorly; dorsal fin bright yellow, with basal part of spinous part of fin greyish yellow in larger juveniles; anal fin bright yellow; caudal fin bright yellow basally with remainder of fin hyaline in small juveniles, the yellow area becoming more extensive to cover most of fin in larger juveniles; pectoral fins are hyaline; pelvic fins greyish hyaline, edged in pale blue (Ref. 120429).
Usually frequents deep reefs with some sponge and coral cover, reaching 86 m, although sometimes recorded at shallower depths of 25 m. Associates with species of the genera <>Sacura, Pseudanthias, Tosanoides and Pseudolabrus (Ref. 120429).

= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00792 - 0.03811), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.1 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.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
