Found over sandy substrate. Juveniles use estuaries as nurseries (Ref. 27121). Feeds on worms, crustaceans, and mollusks especially mussels (Ref. 5213). Spawns during spring and summer close inshore (Ref. 36731).
Conflicting descriptions of the reproductive style of this species have been reported, e.g., Ref. 4359 describe this species as being a gonochorist (Ref. 28504). Also Ref. 103751.
