Maturity: Lm ?  range ? - ? cm

Occurs in shallow water. Burrows of individuals are in pairs, approximately 8 inches apart; with neighboring pairs at least 3-4 times greater apart from each other. Usually in moderate sized aggregations that appear during current runs (Ref. 48635). Usually in colonies on sand bottoms near reefs, sheltered bays and coastal sand slopes (Ref 90102).

Estimates based on models
Preferred temperature (Ref. 115969
): 26 - 29.3, mean 28.6 °C (based on 1709 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±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 to moderate vulnerability (28 of 100) .
