Colored engraving of a live Pomacea paludosa made by Helen Lawson († 1854) and published in 1845 A monograph of the freshwater univalve Mollusca of the United States: including notices of species in other parts of North America by Samuel Stehman Haldeman.
This species is the largest freshwater gastropod native to North America.[3]
The shell is globose in shape. The whorls are wide, the spire is depressed, and the aperture is narrowly oval.[3] The shells are brown in color, and have a pattern of stripes.
The shell is 60 millimetres (2.4 in) in both length and width.[3]
The maturation of eggs of Pomacea paludosa: freshly laid eggs in a thick mucus matrix have a salmon coloration (left). Mature eggs in calcified shells are pinkish white in color (right).
This is a tropical species. It is amphibious, and can survive in water bodies that dry out during the dry season.[3]
