Maturity: Lm ? range ? - ? cm
Max length : 35.0 cm TL самец/пол неопределен; (Ref. 9626); common length : 25.0 cm TL самец/пол неопределен; (Ref. 3702)
Inhabits the surf zone along sandy beaches, but in clear water. Also occurs over muddy bottoms in estuaries and sometimes near coral reef areas. Feeds on small crustaceans washed out of sand by the surf (Ref. 5521). Large specimens are marketed mostly fresh; smaller ones are used as bait.

Estimates based on models
Preferred temperature (Ref.
123201): 23.4 - 28, mean 26.1 °C (based on 376 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00549 - 0.01319), b=3.09 (2.96 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.2 se; based on diet studies.
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
