Morphology | Morphometrics
(total): 16 - 17;
soft rays: 21 - 22. Diagnosis: Dorsal fins III + XIII-XIV + 10-11; anal fin I, 21-22; pectoral rays 13-14: 3 + 5-6 + 5, some branched. LL, pored scales 10-11, notched scales 26-27, starting at 2 scale rows below the end of the pored series; nape and abdomen scaleless. Body depth 5.0-6.0 in SL. Head 3.4-4.7 in SL; dentary pores 2+2+2; eyes large, diameter 3.0-3.5 in head length; orbital cirrus small and lobate; supratemporal sensory canal U-shaped; first dorsal fin about equal or may be lower in height to second. Key features are: body anteriorly greenish, remainder of body transparent, with bars 8-9 narrow, faint orange; female first dorsal fin lower than second, male same height as second; membrane between first two spines pigmented (Ref. 57774, 88983).
Adults usually occur on lagoon outer reef flats, 0.5-5 m (Ref. 88983). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 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 (10 of 100) .
