Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10-11; Anal spines: 1; Anal soft rays: 9 - 10; Vertebrae: 26. Upper pectoral fin rays entire. Nape with as many as 30 dark spots.

Predorsal cycloid scales 7-9, trunk ctenoid. In male, anal fin when appressed reaching almost the caudal fin; appressed 2nd dorsal fin overlapping caudal. Anal and 2nd dorsal fins of female when appressed reaching to within a distance of 2-3 scales of caudal fin (Ref. 420); longitudinal scale series 30-32; depth of body 4.9-5.6 in SL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Found in sandy areas with both living coral and coral rubble, and from both moderately clear and turbid water (Ref. 48637).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00412 - 0.01928), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (16 of 100) .
