Biology and ecology

Lives in slow-moving water such as lakes, pond, irrigation canals, ditches and slow moving streams. It is a benthic grazer and filter feeder, feeding on benthic and epiphytic diatoms often found on sandy to muddy substrates.


China, Japan, Korea, Eastern Russia, Thailand, Vietnam, Laos, India, Burma and Malaysia. Introduced into other parts of the world including the United States, Canada, Europe and Australia.


This taxon is a source of food in parts of Asia. Two species in this genus have been recorded as invasive. Only one species has so far been recorded from Australia (Cipangopaludina japonica) which is (so far) restricted to one locality north of Sydney where it is sold from open concrete ponds.
