Members of this genus live 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 substrata.
China, Japan, Korea, Eastern Russia, Thailand, Vietnam, Laos, India, Myanmar and Malaysia. Introduced into other parts of the world including the United States, Canada, Europe and Australia.
Members of this genus are a source of food in parts of Asia. Two species 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.
