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.
