About Pomacea paludosa (Say, 1829)
Pomacea paludosa (Say, 1829) is the largest native North American freshwater gastropod. Its shell is globose with wide whorls, a depressed spire, and a narrowly oval aperture. Shells are brown with a striped pattern, and typically measure 60 millimetres (2.4 in) in both length and width. The snail’s native range includes central and southern Florida, Cuba, and Hispaniola. Its non-native range covers northern Florida, and it has also been recorded in Georgia, Oahu Hawaii, Louisiana, and Oklahoma. This is a tropical amphibious species that has both gills and lungs, and can survive in water bodies that dry out during the dry season.
