Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 9273); common length : 40.0 cm TL male/unsexed; (Ref. 9273); max. reported age: 11 years (Ref. 56049)
Adults inhabit inshore areas, including bays (Ref. 2850). Form schools (Ref. 2850). Demersal spawners in nearshore habitats (Ref. 56049). Oviparous, with planktonic, primarily neustonic larvae (Ref. 36497). Eggs are attached to one another by spawning substrate via adhesive filaments (Ref. 36497). Sold fresh (Ref. 2850).
