Epioblasma Florentina
''Epioblasma'' is a North American 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 make use of 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
''Epioblasma brevidens'', the Cumberlandian combshell, 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 (ESA). 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 long. Its 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 their shell, which appears inflated. These mussels live in shoals and in coarse sand and boulders in medium streams to large rivers. Combshells tend to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epioblasma Lenior
''Epioblasma lenior'', the narrow catspaw or Stone's pearly mussel, was a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species was endemic to the Tennessee River system in the United States. Its natural habitat was gravel and sand in clear, fast flowing water. It became extinct due to habitat loss and pollution. The last remaining population was in the Stones River, Tennessee Tennessee (, ), officially the State of Tennessee, is a landlocked U.S. state, state in the Southeastern United States, Southeastern region of the United States.

Epioblasma Propinqua
''Epioblasma propinqua'', the Tennessee riffleshell or nearby pearly mussel, is an extinct 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 or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ... 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.

Epioblasma Florentina Walkeri
''Epioblasma walkeri'', common name the tan riffleshell, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. Many scientists now recognize this mussel as synonymous or a subspecies of the presumed extinct ''Epioblasma florentina'' due to integrating shell characteristics between them. At the time of its listing in 1977 under the Endangered Species Act of 1973, its range was limited to the lower Red River (Cumberland system), the middle fork of the Holston River, a possible population in the Stones River, the Duck River, where its population was threatened by a proposed Tennessee Valley Authority dam, and the Clinch River. The population in Indian Creek in the upper Clinch River basin was proposed as a separate subspecies by Jones, Neves, Ahlstedt and Hallerman in 2006. It is listed under Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora CITES (shorter acronym for the Co ...

Epioblasma Capsaeformis
The oyster mussel (''Epioblasma capsaeformis'') is a rare species of freshwater mussel in the family Unionidae.

Epioblasma Ahlstedti
''Epioblasma ahlstedti'', commonly called the Duck River dartersnapper, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. It is native to Alabama and Tennessee in the southeastern United States, where it is endemic to the Tennessee River drainage. Although it is currently known only from the Duck River in Tennessee, museum specimens document that it was also historically found in the Buffalo River, the main stem of the Tennessee River at Muscle Shoals, and in Shoal Creek, Alabama. Like many freshwater mussels, this species has experienced extreme habitat loss and is now considered to be critically imperiled by NatureServe. The last remaining populations are found only in a 30-mile stretch of the Duck River, one of the most biologically diverse rivers in North America. This species was described to science in 2010, distinguishing it from the closely related (and also endangered) ''Epioblasma capsaeformis The oyster muss ...
