Some pairs of moderately large canines in anterior part of both jaws, 6 to 13 lateral teeth in lower jaw, stronger and more widely spaced than those of upper jaw. Gill rakers pointed, longer than broad. Soft ray count of pectoral fin refers to that on ocular side (Ref 9774).
Found in shallow waters and estuaries, on mud and sand bottoms, to depths of 200 m (Ref. 30573). Juveniles common in brackish water (Ref. 9774). Feeds on benthic animals (Ref. 5213). Mainly sold fresh (Ref. 9774).

Estimates based on models
Preferred temperature (Ref.
123201): 21.4 - 28.5, mean 27 °C (based on 1365 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00476 - 0.00728), b=3.16 (3.11 - 3.21), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.7 se; based on diet studies.
Generation time: 6.9 ( 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 (K=0.16; tmax=7).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
Nutrients (Ref.
124155): Calcium = 105 [47, 197] mg/100g; Iron = 0.9 [0.5, 1.7] mg/100g; Protein = 16.9 [14.8, 18.9] %; Omega3 = 0.154 [0.076, 0.302] g/100g; Selenium = 62.3 [26.9, 142.5] μg/100g; VitaminA = 25.3 [6.7, 101.3] μg/100g; Zinc = 0.9 [0.6, 1.4] mg/100g (wet weight);
