Morphology | Morphometrics
soft rays: 92 - 102;
Vertebrae: 67 - 69. This species is characterized by the following features: D 116-129 (usually 119-125); A 92-102 (usually 98-100); pectoral fin rays 19-21 (rarely 20); precaudal vertebrae 16-17 (usually 17); caudal vertebrae 50-52 (usually 51), total vertebrae 67-69 (usually 68); gill rakers on first gill arch with 2 rudiments above, 4 developed but short gill rakers below; short, blunt and bulbous head; dorsal tissue of head usually flaccid, inflated; subterminal mouth; dorsal and ventral profiles of body nearly parallel for much of its length; unmarked body; short and unequal pelvic-fin rays, longer reaching under anterior third of opercle (Ref. 81834).
Occurs over sand and mud bottom (Ref. 81834). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Preferred temperature (Ref. 115969
): 17.5 - 26.5, mean 23 (based on 70 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
): 3.5 ±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
