Shell description

Five views of a shell of Pomacea paludosa

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]

Distribution

The indigenous distribution of this snail is central and southern Florida,[4] Cuba and Hispaniola.[5]

The nonindigenous distribution includes northern Florida. The species has also been found in Georgia, Oahu, Hawaii (Devick 1991)[citation needed], Louisiana, and Oklahoma.[5]

Ecology

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]

Applesnails have both gills and lungs.
