Clappia is a genus of small freshwater snails that have an operculum, aquatic gastropod mollusks in the family Lithoglyphidae. [2] [3]
Generic name Clappia is in honor of malacologist George Hubbard Clapp. [1]
There are two [3] species within the genus Clappia:
Comparison of apertural views of both species:

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.
Succinea, common name the amber snails, is a large genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Succineidae.
Poirieria is a genus of large predatory sea snails, marine gastropod molluscs in the subfamily Pagodulinae of the family Muricidae, the rock snails.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum.
Physidae, commonly called the bladder snails, is a family of small air-breathing freshwater snails, aquatic pulmonate gastropod molluscs in the superfamily Lymnaeoidea.
Physella is a genus of small, left-handed or sinistral, air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the family Physidae.
The Cahaba pebblesnail, scientific name Clappia cahabensis, is a species of very small freshwater snail, aquatic gastropod mollusks in the family Lithoglyphidae.
Clappia umbilicata, the umbilicate pebblesnail, was a species of small freshwater snail that had an operculum, an aquatic gastropod mollusk in the family Lithoglyphidae. This species is now extinct.
Fluminicola is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Lithoglyphidae.
Pleurodonte is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Pleurodontinae of the family Pleurodontidae.
Somatogyrus is a genus of very small freshwater and brackish water snails that have an operculum, aquatic gastropod micromolluscs in the family Lithoglyphidae.
The Savannah pebblesnail, scientific name Somatogyrus tenax, is a species of freshwater snail, an aquatic gastropod mollusk in the family Hydrobiidae. This species is endemic to the United States. Somatogyrus tenax may actually be a junior synonym of Somatogyrus virginicus, although the taxonomy remains in dispute.
Assimineidae is a family of minute snails, also known as palmleaf snails, with an operculum, gastropod mollusks or micromollusks in the superfamily Rissoidae. Many of these very small snails live in intermediate habitats, being amphibious between saltwater and land; others live in freshwater.
The Littorinidae are a taxonomic family of over 200 species of sea snails, marine gastropod molluscs in the clade Littorinimorpha, commonly known as periwinkles and found worldwide.
Pyramidula is a genus of very small, air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the family Pyramidulidae.
Skenella is a genus of minute sea snails, marine gastropod mollusks in the family Cingulopsidae.
Asolene is a genus of freshwater snails with an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails.
Retusa is a genus of very small head-shield sea snails or barrel-bubble snails, marine gastropod mollusks in the family Retusidae.
