Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Ampullariidae
Ampullariidae, commonly known as the apple snails, is a family of large freshwater snails, aquatic gastropod mollusks with a gill and an operculum. These snails simultaneously have a gill and a lung as functional 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 organism is either male or female. Systematics and taxonomy Ampullariidae belongs to the superfamily Ampullarioidea, and is also its type family. It comprised two subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, which followed the classification proposed by Berthold (1991), including Ampullariinae Gray, 1824, and Afropominae Berthold, 1991. The current classification accepted by WoRMS includes Ampullariinae and Pomaceinae Starobogatov, 1983. Genera Ampullariidae are probably of Gondwanan origin, and the divers ...

Pomacea
''Pomacea'' is a genus of freshwater snails with gills and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. The genus is native to the Americas; most species in this genus are restricted to South America. in the aquarium trade these snails are sometimes called ''Pomacea'' or incorrectly ''Ampullarius'', and in English as "olormystery snail" or "apple snail". Some species have been introduced outside their native range and are considered invasive because of their voracious appetite for plants. Because of this, imports involving this genus are restricted in some regions (including the United States) and are entirely banned in others (including the EU).Dawes, J. (14 January 2013).
