Benthic (Ref. 58302). Forms congregations in confined sandy areas of sandy bottoms (Ref. 30874) where it buries itself using its pointed snout or its bony, sharp tail. May feed on small fishes, crabs, and prawns (Ref. 30874).

Estimates based on models
Preferred temperature (Ref. 123201
): 24.3 - 28.8, mean 27.3 °C (based on 624 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00044 - 0.00239), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.67 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100).
