The mantle of this cowry is translucent bright orange-red. Cribrarula cribraria is one of the most recognizable cowries. The shells reach 10–44 millimetres (0.39–1.73 in) of length. These shells are smooth, their basic coloration is pale brown or fawn, with several circular white spots. The edges of the shell are white, as is the flat base.
These quite uncommon shells reach on average 10–25 millimetres (0.39–0.98 in) of length. The basic color and pattern of this species are quite variable. The dorsum surface is smooth and shiny, its color is white or pale pink, with many brown spots, while the edges and the extremities are orange with darker spots extended to the base.

Zoila thersites, the humpbacked cowry or black cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. Subspecies [ edit ]
The largest known fossil cowry was Gisortia gigantiea Munster, 1828 which reached a length of 350mm. The largest modern cowry is the Atlantic Deer Cowry ( Macrocypraea cervus ) at up to 190mm. The largest known cowry from any extant subfamily or genus was the Australian cowry Zoila (Gigantocypraea) gigas (McCoy, 1867) at about 247mm.
Cowrie or cowry (pl. cowries) is the common name for a group of small to large sea snails in the family Cypraeidae. The term porcelain derives from the old Italian term for the cowrie shell (porcellana) due to their similar appearance. [1] Cowrie shells have held cultural, economic, and ornamental significance in various cultures.
Juvenile cowry shells are not at all similar to adult cowry shells. The juvenile shells of cowries perhaps more closely resemble the shells of some "bubble snails" in the order Cephalaspidea. Also the shells of juvenile cowries seldom exhibit the same color patterns as the adult shells do, and thus can be hard to identify to species.
The surface may also be completely grey-greenish. The margins are white or pale brown, with some dark dots and a pronounced labial 'callus'. The base is white or pinkish with fine short teeth. In the living cowries mantle is orange-reddish, with white sensorial papillae. Mantle and foot are well developed, with external antennae.
