Lasmigona Decorata
The Carolina heelsplitter (''Lasmigona decorata'') is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae. It is named the "Carolina heelsplitter" because in life the sharp edge of the valves protrudes from the substrate and could cut the foot of someone walking on the river or stream bed. This species is endemic to the United States and is found in only North Carolina and South Carolina. This species current status is classified as "critically endangered". The IUCN Red List website states that to be considered critically endangered means that the species is facing an extremely high risk of becoming extinct in the wild in the immediate future. Description The first recorded encounter with the Carolina heelsplitter was in 1852 by Isaac Lea. He described this new creature as ''Unio decoratus''. The largest recorded specimen was about five inches long. This freshwater mussel has a shell which is greenish-brown to dark brown on the outside. The ...

Lasmigona Subviridis
The green floater (''Lasmigona subviridis'') is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species is endemic to the United States. It is found in West Virginia, Delaware, Maryland, Tennessee, North Carolina, Pennsylvania, New Jersey, Virginia and New York, and has been extirpated from Alabama and Georgia. Its populations in the Susquehanna River and the Potomac River are considered to be genetically distinct from the southern population. As of 2023, the species is under review for listing under the Endangered Species Act of 1973. It is reported to be a simultaneous hermaphrodite Simultaneous hermaphroditism is one of the two types of hermaphroditism, the other type being sequential hermaphroditism. In this form of hermaphroditism an individual has sex organs of both sexes and can produce both gamete types even in the sam ... under most conditions.

Lasmigona Alabamensis
''Lasmigona alabamensis'', common name Alabama heelsplitter, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae. Confusingly, a different species, ''Potamilus inflatus'', has also sometimes been listed as "Alabama heelsplitter". In order to avoid confusion, that species has now been given the common name In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrast ...

Lasmigona Compressa
''Lasmigona compressa'', the creek heelsplitter, is a species of freshwater mussel, an aquatic bivalve in the family Unionidae. This species is found in the northern region of North America. It is native to the Canadian interior basin, and the drainages of the St. Lawrence River and the Ohio River The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illino ....

Unionidae
The Unionidae are a family of freshwater mussels, the largest in the order Unionida, the bivalve molluscs sometimes known as river mussels, or simply as unionids. The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks. Origin and early diversification The recent phylogenetic study reveals that the Unionidae most likely originated in Southeast and East Asia in the Jurassic, with the earliest expansions into North America and Africa (since the mid-Cretaceous) followed by the colonization of Europe and India (since the Paleocene). Life history Unionidae burrow into the substrate, with their posterior margins exposed. They pump water through the incurrent aperture, obtaining oxygen and food. They remove ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Freshwater Mussel
Freshwater bivalves are one kind of freshwater mollusc, along with freshwater snails. They are bivalves that live in fresh water as opposed to salt water, which is the main habitat type for bivalves. The majority of species of bivalve molluscs live in the sea, but in addition, a number of different families live in fresh water (and in some cases, also in brackish water). These families belong to two different evolutionary lineages (freshwater mussels and freshwater clams), and the two groups are not closely related. Freshwater bivalves have a simple morphology that varies among taxa, and are distributed around most regions of the world. Species in the two groups vary greatly in size. Some pea clams (''Pisidium'' species) have an adult size of only 3 mm. In contrast, one of the largest species of freshwater bivalves is the swan mussel, in the family Unionidae; it can grow to a length of 20 cm, and usually lives in lakes or slow rivers.
