Epioblasma Sulcata Perobliqua
''Epioblasma'' is a genus of freshwater mussels, Aquatic animal, 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.

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.
