Short description Morphology | Morphometrics

Dorsal spines (total): 1 - 2; Dorsal soft rays (total): 29-33; Anal spines: 0; Anal soft rays: 25 - 30. Dark brownish green to grayish green head and back, lower portions noticeably whitish; dark brown to pale orange iris; dark brown lips. Caudal fin membranes usually orange anteriorly, dusky posteriorly; other fins clear; spinous dorsal similar to body color. Pelvic fin rudiment moderate in size, broadly attached to posterior margin of ventral flap. Midbody scales variable in size. Scale rugosities in males usually develop at about 50 mm SL. Varies considerably with respect to squamation, coloration, fin-ray counts and max. size across its range.

Biology     Glossary (e.g. epibenthic)

Secretive species found in lagoon and protected seaward reefs (Ref. 9710, 48637), often in silty conditions. Solitary (Ref. 90102). Sometimes seen deep inside branching corals (Ref. 48637). Has been from deeper water by trawls.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.01063 - 0.04504), b=2.91 (2.73 - 3.09), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.4 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) .
