''Fragum unedo'' is a species of cockle, a marine bivalve mollusc in the family Cardiidae, commonly known as the Pacific strawberry cockle. It is found in tropical seas in the Indo-Pacific region and the empty shells are prized for use in decorative crafts.〔(''Fragum unedo'' (Linnaeus, 1758) ) SeaLifeBase. Retrieved 2011-10-21.〕 ==Description==
''Fragum unedo'' can grow to 6.5 cm (2.5 in) in length but 4 cm (1.5 in) is a more usual size. The two domed valves are equal in size and asymmetric, with the beaks in front of the mid line. The outline is sub-quadrate with steeply sloping dorsal margins. The posterior margin is long and almost straight while the anterior margin is evenly rounded. They meet at a distinct, nearly square angle. The strong radial ribs often have small red, thorn-like sculpturing. The margin is deeply crenulated. The texture of the shell is robust, the colour being mainly white but sometimes mottled with reddish mosaic patches.〔〔(''Fragum unedo'' (Linnaeus, 1758) ) Encyclopedia of Life.
