Morphology | Morphometrics
soft rays: 9 - 11. Characterized by translucent grey body color with brown and white spotting and row of double spots just below midlateral scale row; united pelvic fins, frenum present; rounded caudal fin, about equal to HL; longitudinal scale series 28; ctenoid scales on body and nape; predorsal scales 10; cheek and opercle without scales; depth of body 6.1 in SL (Ref. 90102).
Inhabits sand patches (Ref. 37816) and fine rubble flats adjacent to reef to about 10 meters depth. Usually occurs on light coloured sand and is often partly burried (Ref. 48637). Uncertain if it associates with invertebrate burrows.

Estimates based on models
Preferred temperature (Ref. 115969
): 28.5 - 29.3, mean 28.9 °C (based on 448 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00415 - 0.01826), b=3.07 (2.90 - 3.24), 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. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (16 of 100) .
