Epioblasma
''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. The genera has also been identified as ''Dysnomia''. ==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 Unionidae family, this was the first time that "fish snapping" behavior had been observed. Examination of other species within the ''Epioblasma'' genus may further reveal unusual reproductive mechanisms.〔http://unionid.missouristate.edu/gallery/Epioblasma/default.htm〕
