Palmadusta diluculum, the 'Day-Break Cowry', is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.[1]
Description
These quite common shells reach on average 25–29 millimetres (0.98–1.14 in) of length, with a maximum size of 36 millimetres (1.4 in) and a minimum size of 25 millimetres (0.98 in). The shape of these shells is somewhat pyriformly ovate, the basic coloration is brown or violet-chesnut, with two or more zones of several white dorsal zigzag-bands and distinctive dark spots on the white base. The extremities are edged with dark chesnut areas. In the living cowry the mantle is thin and smooth. The Palmadusta diluculum virginalis subspecies is smaller, the terminal spots are less accentuated to absent and dark spots on the base are totally missing.
