Found in seagrass beds in estuaries (extremely common during reproductive season in the austral Spring) and coastal bays, and sponge gardens on inshore reefs. Venomous dorsal spines often inflict a painful sting to fishers (Ref. 34095, 39597). Of no commercial importance but often entrapped in fishing gears such as trawls and can be dangerous to fishermen who attempt to remove these (Ref. 39597).
