Viviparus malleatus is a species of large, freshwater snail with an operculum and a gill, an aquatic gastropod mollusk in the family Viviparidae, the river snails.
Originally from Japan, V. malleatus has been introduced to various areas along the Pacific coast of North America.[1]
Description
The shell is described as thin and "egg-shaped"[2] with very rounded whorls. The spire is short, and the apex may become worn out in older specimens.[2] The name malleatus derives from Latin malleāre (to hammer) and refers to the "hammered-like sculpture" often found on the shell of this species.[2]
