Flower hat jellies can be found throughout the coastal waters of southern Japan in the Pacific and Brazil and Argentina in the Atlantic.
Here in Baltimore, the exhibit space for these jellies is specially lit to accentuate their fluorescent tentacles and contains a substrate in which they spend most of their time.
As a benthic species they occasionally swim up into the water column, but mostly rest on the grate provided for them. Here you can see their tentacles which hang below, as well as those on the tops of their bells!
