Craspedacusta sowerbii, known as the the peach blossom jellyfish or freshwater jellyfish, is found in slow-flowing and stagnant waters where the shore zone can warm considerably. Its diet consists of small crustaceans, rotifers and protozoa.

Freshwater jellyfish are harmless to humans and have nothing to do with poor water quality. It is the only freshwater species of the genus Craspedacusta that has spread beyond East Asia.
