Cipangopaludina malleata is a species of large, freshwater snail with an operculum and a gill, an aquatic gastropod mollusk in the family Viviparidae, the river snails.

[2] Originally from Japan, C. malleata has been introduced to various areas along the Pacific coast of North America.

[1] The shell is described as thin and "egg-shaped"[3] with very rounded whorls.

The spire is short, and the apex may become worn out in older specimens.

[3] The name malleatus derives from Latin malleāre (to hammer) and refers to the "hammered-like sculpture" often found on the shell of this species.
