Ecology
''Sinanodonta woodiana'' is a species of East Asian unionid mussel, primarily from the Amur River and Yangtze rivers. The Chinese pond mussel can reach sizes of up to 30 cm and an age of 12–14 years. Yet, they can reproduce in their first year while only 3–4 cm in size.
This large freshwater mussel is a habitat generalist with high silt tolerance. It is established worldwide despite having, like all unionid mussels, an obligatory parasitic stage (glochidium), which must encyst on host fish. The species is a broad host generalist, which can complete its development on all fish species tested, both coinvasive and native.

The presence of S. woodiana can seriously influence indigenous unionid populations.
''Sinanodonta woodianas great success is attributed to importation and commercialization of Asian carp, its native host. S. woodiana was introduced in Tuscany both inadvertently, and for artificial pearl production. The species is also sold in garden centers as biofiltration for artificial ponds.
