Epioblasma Florentina Aureola
''Epioblasma'' is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. Most of the species in this genus have been lost in modern times, and the entire genus is threatened with the possibility of extinction. Reproduction All Unionidae are known to use the gills, fins, or skin of a host fish for nutrients during the larval glochidia stage. It was discovered in 2004 that female ''Epioblasma'' in the subgenus ''Torulosa'' transfer their parasitic larvae to the host fish by snapping onto the head of the fish and pumping the larvae into the host fish's gills. While using bait to lure host fish towards the larvae is common in the family Unionidae, this was the first time that "fish snapping" behavior had been observed. Examination of other species within the genus ''Epioblasma'' may further reveal unusual reproductive mechanisms.

Epioblasma Brevidens
The Cumberlandian Combshell (''Epioblasma brevidens'') is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae. This species is endemic to the United States, found mainly in the states of Tennessee and Virginia. This mussel resides in medium-sized streams to large rivers. The combshell is an endangered species and protected under the Endangered Species Act of 1973. The combshell is threatened by habitat modifications and pollution. Description and physical characteristics The Cumberlandian combshell (Epioblasma brevidens) is a brown and yellow mussel that is about 2 inches long. Its brown solid shell has a yellow and brown film-like coating. The shell also has many green rays on it. The inside of the mussel is pearl-white. Female combshells also have serrated teeth-like structures around the edge of its shell. These mussels live in shoals and in coarse sand and boulders in medium streams to large rivers. Combshells tend to live in depths of less ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Epioblasma Metastriata
The upland combshell (''Epioblasma metastriata'') was a species of freshwater mussel in the family Unionidae. It was endemic to the upper Mobile River Basin in the southeastern United States. This species was found only in the shoals of rivers and large streams. This habitat has been massively impacted by dam construction and dredging. Due to habitat loss and pollution, this species is considered extinct. The last live individual was seen in 1988, in the Conasauga River. Surveys conducted after that time have failed to find any live individuals in any of their previously known locations, and in 2021 the United States Fish and Wildlife Service proposed officially labeling them as extinct. There remains the possibility that this species could still exist in sections of the Upper Coosa River The Coosa River is a tributary of the Alabama River in the U.S. states of Alabama and Georgia.

Epioblasma Sampsonii
''Epioblasma sampsonii'', the Wabash riffleshell or Sampson's naiad, was a species of freshwater mussel in the family Unionidae. It is now extinct. The species was endemic to the United States, where it was found in the drainages of 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 ..., living in gravel and sand shoals. Like all other members of its genus, its populations declined greatly from early dam and canal construction. The extinction of this species is believed to have occurred sometime in the early 20th century. Little is known about the biology and ecology of this species.

Epioblasma Propinqua
''Epioblasma propinqua'', the Tennessee riffleshell or nearby pearly mussel, was a species of freshwater mussel in the family Unionidae. It was endemic to the United States, where it was found in the drainages of the Cumberland River, Ohio River, and Tennessee River. Like most other members of its genus, it became extinct due to habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... in the form of dam construction, dredging, and pollution. This species was particularly sensitive to these effects, and appears to have declined greatly during early industrialization. The last live collection was made in 1901.

This species was endemic to the drainages of the Cumberland River and the Tennessee River in the United States. It was known from several locations in Kentucky, Tennessee, and Alabama. Its natural habitat was shallow, fast moving water of major rivers. It became extinct due to habitat loss, as the rivers were dammed and diverted.
