Uncommon species found from near shore to 75 m depth (Ref. 34024). Inhabit bottoms with fine sand, mud, rubble or marine plants, at moderate depths (Ref. 9329). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Frequently caught by shrimp trawlers (Ref. 9329). Minimum depth from Ref. 58018.

Estimates based on models
Preferred temperature (Ref. 115969
): 18.1 - 27.5, mean 23.4 °C (based on 22 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00127 - 0.00572), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.7 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 (27 of 100) .
