Donax vittatus, or the banded wedge shell, is a species of bivalve mollusc in the order Cardiida.

The valves are delicate and glossy and are found in a wide range of colours including white, yellow, brown, pink and violet.

The annual growth rings can be seen and these are often more deeply pigmented than the rest of the shell There may also be pale radial rays.

On the inside of the shell, the muscle scars are indistinct and the oval pallial sinus extends to the middle of the valve.

The fringed mantle and the strong muscular foot are mauve or reddish, and the pair of short, separate siphons are orange.

Donax vittatus is a filter feeder and, at the same time that oxygen is being extracted from the water stream by the gills, food particles are captured and passed by cilia to the mouth.
