Pomacea paludosa. The Pilidae [synonym Ampullariidae] are peculiar because they have both gills and lung, the mantle cavity being divided to separate the two types of respiratory structures. Basically aquatic snails, the lung probably arose because of the snails' habitats - living in shallow water habitats that dry out for part of the year. Pilid snails have a siphon for taking in air when submerged.
