Ampullariidae

Ampullariidae, common name the apple snails, is a family of large freshwater snails, aquatic gastropod mollusks with a gill and an operculum. This family is in the superfamily Ampullarioidea and is the type family of that superfamily. The Ampullariidae are unusual because they have both a gill and a lung, with the mantle cavity being divided in order to separate the two types of respiratory structures. This adaptation allows these snails to be amphibious. This family is considered to be gonochoristic unlike some others. This means that in order to breed, a male and female snail are needed.
