DistributionRead full entry
The northern distribution limit of Cassiopea xamachana is the southeastern tip of the United States as upside-down jellyfish appear in large numbers in varying areas of the Florida Keys. This species is also found in Bermuda, the Caribbean Sea and warmer areas of the western Atlantic Ocean. They are commonly found in places such Walsingham Pond and Harrington Sound, on the bottom of an inshore bay or pond. The highest density of these scyphozoans occurs in the Caribbean but throughout the course of the last decade the distribution seems to be expanding to other locations such as the Hawaiian and Mediterranean waters, including the Red Sea.
