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.
Leporicypraea mappa (previously known as Cypraea mappa), common name the map cowry, is a species of large sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. This is considered an economically important species in the Indo-West Pacific , where it is usually collected both for food and for shell trading.
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. Cowries have no operculum.
The shells of these cowries reach on average 30–38 millimetres (1.2–1.5 in) of length, with a minimum size of 16 millimetres (0.63 in) and a maximum size of 62 millimetres (2.4 in). They are quite variable in pattern and color.
The common name Arabian cowry is based on a dense and irregular pattern of thin longitudinal brown lines which are sometimes interrupted by empty spaces, giving an appearance that is considered to be similar to that of Arabic script. Mauritia arabica and its close relative Mauritia eglantina have very similar shells which can be easily confused.
As is the case in most cowries, the subadult shell of Cypraea tigris has a different color pattern. The apex of the shell is a barely visible tubercule at the top right of the shell image. Roughly egg-shaped and dextral, the glossy shell is large and heavy for a cowry. It measures up to 15 cm (6 in) in length, and the upper or dorsal side is ...
The shells of these very common cowries reach on average 23–28 millimetres (0.91–1.10 in) of length, with a minimum size of 12 millimetres (0.47 in) and a maximum size of 39 millimetres (1.5 in). They are very variable in pattern and colour.
The shells of these common cowries reach on average 50–75 millimetres (2.0–3.0 in) of length, with a minimum size of 26 millimetres (1.0 in) and a maximum size of 97 millimetres (3.8 in). They are very variable in pattern and colour. The shape ranges from oval to rhomboidal.
