Occurs over shallow muddy and sandy bottoms of the continental shelf), mainly near estuaries and sometimes entering rivers (Ref. 57343). Feeds mainly on small benthic crustaceans, especially prawns and crabs, and small fishes. Percentage of fishes eaten increases with size. Utilized fresh, dried or salted and frozen; eaten steamed, pan-fried, broiled and baked (Ref. 9987).

Estimates based on models
Preferred temperature (Ref.
123201): 23.7 - 28.1, mean 26.3 °C (based on 82 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00269 - 0.01173), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.67 se; based on food items.
Generation time: 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1
