Gastropods are defined as snails and slugs, belonging to a larger group called Molluscs. Gastropods have unique reproductive systems, varying significantly from one taxonomic group to another. They can be separated into three categories: marine, freshwater, and land. Reproducing in marine or freshwater environments makes getting sperm to egg much easier for gastropods, while on land it is much more difficult to get sperm to egg. The majority of gastropods have internal fertilization, but there are some prosobranch species that have external fertilization. Gastropods are capable of being either male or female, or hermaphrodites, and this makes their reproduction system unique amongst many other invertebrates. Hermaphroditic gastropods possess both the egg and sperm gametes which gives them the opportunity to self-fertilize.
