Some time later the snails spread to Hawaii, South-West Asia and even Florida. They have an operculum which enables the snail to seal the shell entrance to prevent drying out while they are buried in the mud during dry periods. Only wild or specifically cultured apple snails are fit for human consumption; those found in domestic aquaria may be unsuitable. The giant apple snail is prolific, producing egg clutches of 2,000 eggs, as compared to 250 for the channeled apple snail or 20 to 30 for the Florida apple snail. Additionally the imported snails (like the native apple snail population, Pila) were able to transfer a parasite called Angiostrongylus cantonensis (rat lungworm). Alabama Malacological Research Center.

Apple snails include species that are the biggest living freshwater snails on Earth. Journal of Conchology 24: 421-432. However, most people will use the common name mystery snail or common apple snail. Instead of becoming a valuable food source, the introduced snails escaped and became a serious threat to rice production and the native ecosystems. Several apple snail genera (Pomacea, Pila and Asolene/Pomella) deposit eggs above the waterline in calcareous clutches.
