Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 5217); common length : 12.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 33.00 g (Ref. 118626)
soft rays: 36 - 42. Belly with 17 to 20 + 5 to 7, total 22 to 26 scutes. Eye large, lower jaw projecting; upper jaw with a toothed hypo-maxillary bone between hind tip of pre-maxilla and lower bulge of maxilla blade. Pelvic fins with distinct axillary scale; anal fin long, its origin under middle of dorsal fin base. Scales easily lost (Ref. 188). Bluish gray above, sides silvery (Ref. 37032).
Found inshore, along beaches and down to at least 16 m over a muddy bottom. Enters estuaries, but perhaps not tolerating very low salinities (Ref. 12225).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.8 - 27.9, mean 27.3 °C (based on 82 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00621 - 0.00971), b=3.03 (2.97 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.73 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (16 of 100) .
