Rounded silver-grey fish with a large black patch above the pectoral fin base. Schools of this trevalla are rare along the mainland coast, but occurred moderately commonly around the Tasmanian coast until the 1980s, although not often seen there now. Another member of the family, the silver warehou Seriolella punctata, also schools occasionally in shallow southern waters. That species has a more slender body, a series of dark spots along the middle of the sides, and dusky markings behind the eye.
