Morphology | Morphometrics
Inhabits sand bottoms of subtidal reef flats to a depth of at least 40 m in deep lagoons and outer reef slopes (Ref. 1602). Feeds on small benthic invertebrates (Ref. 89972). Usually buries itself in the sand and only comes out to feed or during courtship (Ref. 48636).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.9 - 28.9, mean 27.6 °C (based on 202 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00408 - 0.02036), b=2.76 (2.58 - 2.94), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 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) .
