Two similar species are marketed as Jack Mackerel, T. murphyi grows larger and has more bony, enlarged scales extending from the base of the tail along the midline of the body.
Available wild caught they are free-swimming marine fish found from bays and harbours to depths of about 500m, mainly schooling over the continental shelf, and caught mostly off southern Australia as bycatch of demersal and midwater trawls, as well as in Tasmanian coastal waters by purse seine. They are a similar size and shape to their close relative, Yellowtail Scad.
