length of 133 millimetres (5.2 in).
The shape is usually long oval, the dorsum surface is smooth and shiny, the basic color is brown, usually with three wide dark brown trasversal bands and several white-bluish spots and a light gray longitudinal mark on the top ('sulcus'). On the sides the white spots become ocellated, showing a small dark brown spots on the center. The base of Macrocypraea zebra shell is pale brown and the long and narrow aperture usually bears long dark brown labial teeth. The interior of the shell may be purple. Macrocypraea zebra is quite similar to Macrocypraea cervus
and Macrocypraea cervinetta
, but it can be easily distinguished on side view by the presence of mentioned ocellated spots, that are missing in the last two species. In the living cowries of Macrocypraea zebra the mantle is greyish, with short sensorial papillae. The mantle may cover the entire shell and can be withdrawn into the shell opening when the cowry is threatened.
