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 dark-toothed cowrie has a medium-sized shell which may grow to 60mm in total length. The shell is generally smooth and caramel-coloured, flecked with pale blue or mauve, but in live specimens is usually covered with the mantle. [4] Variations in shell colour range from pale blue or mauve to dark chocolate brown.
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.
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. [2]
Muracypraea mus, common name the mouse cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.. This species was once considered to belong to the archaic genus Siphocypraea (which now includes only extinct species).
Lyncina sulcidentata, common name the square-toothed cowry or groove-toothed cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. Description [ edit ]

These cowries live in shallow water on coral reef at 5–25 millimetres (0.20–0.98 in) of depth, usually hiding under coral and rocks, feeding on algae or coral polyps. Subspecies [ edit ] Palmadusta humphreysii humphreisii ( Gray , 1825) . accepted, alternate representation
