Cassiopeia, the "Upside-down Jellyfish". Sometimes sold as an aquarium species. These are shallow water lagoon and mangrove swamp animals that use both photosynthesis (via symbiotic algae) and many small mouths scattered on their "tentacles" (eight oral-arms) to suck-in zooplankton for food. Favored foods of Ocean Sunfishes and marine turtles.

Cassiopeia frondosa. Here in Jamaica
