Map cowry

Appearance

The maximum shell length of this species is up to 10 cm, but it more commonly grows up to about 8 cm.

The shell of ''Leporicypraea mappa'' is globose, with a near elliptical, slightly elongate outline. In affinity to other Cypraeidae, the aperture of the shell is very narrow, and relatively long. Both the inner and outer lips are ornamented with arrays of small teeth, though the teeth of the outer lip are shorter and stronger in comparison to the teeth of the inner lip, which are thinner and more numerous. Its dorsal side is normally inflated, while the ventral side of the shell is slightly concave.

The shell is colored white or cream, with several longitudinal brown lines, which are sometimes interrupted by circular empty spaces. The cursory dorsal mantle groove line is dissimilar to the shells general color pattern, completely devoid of lines, thus easily perceivable. Its sinuous appearance, with several branches and notches, makes it a diagnostic character for this species. This exotic color pattern gives an appearance similar to that of ancient maps, hence the specific and common names. Both the ventral side of the shell and the labral teeth may vary greatly in color, assuming shades of white or cream, or even purple, brown, orange or pink.

Naming

Subspecies of ''Leporicypraea mappa'' include according to the World Register of Marine Species :

Distribution

''Leporicypraea mappa'' is widely distributed in the Indo-Pacific. It is present in many regions, including East Africa, Madagascar, southeastern Red Sea, eastern Polynesia, southern
Japan, Australia and New Caledonia.

This exceptionally wide range may possibly be an artifact. Some conchologists claim that the taxonomy of the species is poorly resolved; if the map cowry is discovered to be cryptic species complex, then this could drastically change the range of its distribution.

Habitat

The map cowry lives in the intertidal and sublittoral zones, usually in coral reef areas, dwelling under slabs and stones at depths of 45 m.

Uses

The flesh of the map cowry is edible, and it is commonly collected by local fishermen for food and shell trading wherever it occurs. It is sold in fish markets in the northern Philippines.
The shells of ''Cypraea mappa'' were considered rare, exotic and beautiful, and were highly prized by private shell collectors in the late 1950s.
