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 ...

Unio Crassus
''Unio crassus'', the thick shelled river mussel, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. MolluscaBase eds. (2023). MolluscaBase. Unio crassus Philipsson, 1788. Accessed through: World Register of Marine Species at: https://marinespecies.org/aphia.php?p=taxdetails&id=1044116 on 2023-01-09 ;Subspecies: * † ''Unio crassus jaeckeli'' Modell, 1950 * † ''Unio crassus klemmi'' Modell, 1957 Ecology As part of newly discovered reproductive behaviour, this mollusc crawls up to the edge of the water, exposing its excurrent aperture, and then lets loose a stream of water. The fountain of water often contains glochidia, and it is suggested that this spurting behavior may facilitate dispersal of mussel larvae (video). Decline The thick shelled river mussel declined during the 20th century everywhere in Europe due to deteriorating water quality, habitat fragmentation and host fish limitation.
