Popenaiadini

	Popenaiadini Ambleminae is a subfamily of Freshwater bivalve, freshwater mussel in the family Unionidae. They are found throughout much of eastern North America south to Central America, although fossils are also known from Siberia. Some species have also been introduced to East Asia. They are the most speciose radiation of the Unionidae, with more than 300 species. Fossils of this group date back to the Late Cretaceous.

	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 ...

	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]

picture info	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. 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.

	Ellipsaria ''Ellipsaria lineolata'' is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This is the sole species in the monotypic genus ''Ellipsaria ''. This species is native to the drainage systems of the Mississippi River, the Mobile River, the Tennessee River, and the Cumberland River in the United States. It exists in the midwestern United States, and has also been observed in the east coast and as far south as the Gulf of Mexico. The common name of ''Ellipsaria lineolata'' is the Butterfly Mussel. Description ''E. lineolata'' has a thick, fairly triangular shell with dorsal, anterior, and ventral margins that are rounded. The shells of males have a more compressed shape than that of females. Males' shells are also typically longer, growing up to 12.7 cm long compared to females, whose shells grow to around 7 cm long. The shells of most ''E. lineolata'' have a yellowish color on the outside, but some older mussels have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Dromus ''Dromus dromas'', the dromedary pearlymussel or dromedary naiad, is a rare species of freshwater mussel in the family Unionidae. This aquatic bivalve mollusk is native to the Cumberland and Tennessee River systems in the United States, where it has experienced a large population decline. It is a federally listed endangered species of the United States. This mussel is yellow-green in color with interrupted green rays on the shell. The nacre is white, pink, or reddish. The species got its name from the distinctive hump on the shell of larger individuals.USFWS''Dromus dromas'' Recovery Plan.July 1984. This species lives in clear, clean, fast-flowing water. It cannot tolerate water of poor quality, for example, water with silt.''Dromus dromas''. The Nature Conservancy. Like other freshwater mussels, ...
