Mystery snail Pomacea bridgesi, copyright Stijn Ghesquiere.

Belongs within: Gastropoda.
Contains: Lanistes, Ampullaria.

The Ampullariidae, apple snails, are large freshwater snails characterised by the presence of a lung between the gill and osphradium. Molecular phylogenetic analysis supports division of the family between the Old World Ampullariinae and the New World Pomaceinae. Certain species of Pomacea, such as the golden apple snail P. canaliculata and the mystery snail P. bridgesii, are cultivated for the ornamental aquarium trade and have become introduced outside their native ranges.

Characters (from Simone 2011): Shell globose. Operculum with an upper projection. Osphradium pectinate located on a folded stalk. Lung located between gill and osphradium. Heart with ampulla at anterior aorta.
