Các tia vây lưng cứng (tổng cộng) : 10; Các vây lưng mềm (tổng cộng) : 10; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 9 - 10. Inner surface of pectoral fin without scales. Overall color is silver or whitish, often light brown or olive on upper sides. Each scale on sides has a brown spot forming longitudinal rows. Fins are uniformly clear to slightly yellowish. Fresh specimen have scattered brown flecks on sides. A blackish bar that runs through the eye may also be evident.
