Ampullariidae, whose members are commonly known as apple snails, is a family of large freshwater snails that includes the mystery snail species. They are 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.

The perivitellinefluid is an extracellular fluid found in the eggs of most gastropods and constitutes the main source of nutrition and defense for their embryos. It replaces the egg yolk of other animals, which in snail eggs is reduced to non-nutritive proteinaceous granules with putative enzymatic function.
Pomacea scalaris is a species of freshwater snail of the Ampullariidae family, described by Alcide d'Orbigny in 1835.
Pomacea columellaris is a South American species of freshwater snail in the apple snail family, Ampullariidae.
Pomacea comissionis is a species of freshwater snail in the family Ampullariidae. It was first described by Hermann von Ihering in 1898 as a variety of Ampullaria decussata.
Pomacea sinamarina is a species of freshwater snail in the Ampullariidae family. It was first described in 1792 by Jean Guillaume Bruguière as Bulimus sinamarinus. Its distribution includes French Guiana and Suriname.
Pomacea auriformis is a species of freshwater snail in the family Ampullariidae, described by Lovell Augustus Reeve in 1856 as Ampullaria auriformis. Its distribution is along the Caribbean coast of Central America. There has been debate over whether this species may be a subspecies of Ampullaria hopetonensis.
Pomacea ocanensis is a species of freshwater snail in the Ampullariidae family native to Colombia. Wilhelm Kobelt originally described the species as a subspecies of Ampullaria auriformis in 1914. A critically endangered species, P. ocanensis faces threats of declining habitat quality due to urbanization, local water management, and pollution. It is the only member of Pomacea considered Endangered or Critically Endangered by the IUCN and one of only two Ampullariids to be Critically Endangered.
Pomacea occulta is a species of freshwater snail in the family Ampullariidae. Previously misidentified as the cryptically similar Pomacea maculata, P. occulta was differentiated by Yang et al. in 2019 using DNA barcoding and molecular systematics.
Pomacea fasciata is a freshwater snail in the Ampullariidae family. It is located in Jamaica, Guadeloupe, and Hispaniola. It lays white eggs.
Pomacea prunella is a species of freshwater snail in the family Ampullariidae, native to Brazil. They have also been found in French Guiana. Unlike other New World Ampullariids, P. prunella has a calcified, rather than corneous, operculum.
