The Shortjaw Cisco has a thin elliptical body that is covered with large, smooth scales. It is mainly silver in colour, with olive or tan colouring on the back and a white belly. Its small toothless mouth has a bottom jaw that is often shorter than, or even with, the upper jaw. The gill rakers (or comb-like structures on the inner surface of the bony arch supporting the gill) number between 32 and 46, which is typically less than other cisco species.

Length: 340 to 420 mm (13.3 to 16.4 in)
