Freshwater jellyfish in northern temperate lakes: Craspedacusta sowerbii in British Columbia, Canada
Freshwater jellyfish species of the genus Craspedacusta purportedly originated from the Yangtze River catchment area, China, and have now been observed on all continents except Antarctica. Sightings of C. sowerbii in the Pacific regions of Canada were compiled to document some of the northernmost re...

Freshwater jellyfish species of the genus Craspedacusta purportedly originated from the Yangtze River catchment area, China, and have now been observed on all continents except Antarctica.
