Apple snail

Common card · No. 213988

Ampullariidae (commonly known as apple snails), is a family of large freshwater snails that includes the mystery snail species. They present an operculum and simultaneously have a gill and a lung as respiratory structures, which are separated by a division of the mantle cavity. This adaptation allows these animals to be amphibious. Species in this family are considered gonochoristic, meaning that each individual is either male or female.
