Contradusta pulchella, common name the pretty cowry or beautiful (little) cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.
Description
[edit]The shells of these quite uncommon cowries reach on average 35–38 millimetres (1.4–1.5 in) of length, with a minimum size of 23 millimetres (0.91 in) and a maximum size of 48 millimetres (1.9 in). The surface of the pear-shaped shells is smooth and shiny, their basic color is usually whitish or yellowish, with many small beige spots, two longitudinal irregular dark brown stain-like patches and one or two light brown transversal bands, but their pattern is very variable. The base and the margins are whitish with brown spots, while the teeth are dark brown. In the living cowries the mantle is clear, with long sensorial papillae. Mantle and foot are well developed, with external antennae. The lateral flaps of the mantle may completely hide the shell surface and can be quickly retracted into the shell opening. Contradusta pulchella is quite similar to Erronea pyriformis.
