References
Pomacea paludosa, common name the Florida applesnail, is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails.
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.
