All pulmonate snails are hermaphroditic and have both male and female reproductive organs, but they still mate with other individuals when they can, but they are capable of self-fertilization (  Snails will go through simultaneous reproduction when they do find a mate. Each individual will act as the female and the male during reproduction and both will acquire sperm from the other for fertilization (

The ovitestis is the organ that produces both sperm and eggs, which are released through the hermaphroditic duct. (Thorp, 2010).

The Albumen gland is responsible for distributing nutrients and protein to the eggs before fertilization (Thorp, 2010).

The fertilized eggs of terrestrial snails are usually laid in a soft, moist place that will be protected from predators (Thorp, 2010).

The number of eggs laid varies from species to species, as does the number of times a year fertilization occurs (
