колючие лучи спинного плавника (общее число) : 8 - 9; членистые (мягкие) лучи спинного плавника (общее число) : 25 - 27; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 23 - 25. Body purplish gray when alive; grayish brown when preserved; a region of dull yellow in front of eye, a lesser extension posterior to lower part of eye; outer 1/3 of pectoral fin yellow, extreme distal part hyaline; dorsal and anal fins yellowish grey basally, dull yellow distally; caudal fin base whitish; caudal fin purplish. Anterior gill rakers 16-24, posterior 17-22. Caudal spine small.
Live in various reef habitats, sand slopes and lagoons (Ref. 48637). Juveniles inhabit shallow, protected, turbid inshore waters while adults prefer deeper areas of protected bays and lagoons. Also in outer reef areas (Ref. 1602). Benthopelagic (Ref. 58302). Schooling species, feed on diatoms, detritus film of sand, filamentous algae, hydroids, and pieces of fish (Ref. 1602, 48637). Probably the only surgeonfish that readily takes bait (Ref. 12484).

Estimates based on models
Preferred temperature (Ref.
123201): 23.3 - 29, mean 27.7 °C (based on 2980 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00613 - 0.03255), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.23 se; based on food items.
Generation time: 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
