Jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about 200 described species, or of the class Cubozoa (approximately 20 species). One unique type of jellyfish is Cassiopea xamachana, referred to as the upside-down jellyfish. They are flattish, with four to six flat, short-sided branches projecting from both sides of the mouth, or oral, arms. Jellyfish of the Cassiopea genus are the only ones that rest with their umbrellas on the ocean floor and their tentacles pointing upward.

This means that they, like us, are part of the kingdom Animalia. They are carnivores. It extends its frilly tentacles up into the water column where they capture planktonic food and absorb light that is used by photosynthetic algae that are housed in its body.

Members of the genus measure more than 100 mm (4 inches) in diameter. Most of the large, often colorful, and conspicuous jellyfish found in coastal waters throughout the world are Scyphozoa. This benthic ctenophore (Coeloplana sp) crawls around on the ocean floor and is an example of a group of animals that are likely to be the earliest branching extant clade of animals. Most species of Scyphozoa have two life-history phases, including the planktonic medusa or jellyfish form, which is most evident in the warm summer months, and an inconspicuous, but longer-lived, bottom-dwelling polyp, which seasonally gives rise to new medusae. Commun Biol 3, 67; doi: 10.1038/s42003-020-0777-8 Published in The common name of upside-down jellyfish is associated with the positioning of their body in comparison with the conventional jellyfish. The recently-identified culprit is the upside-down jellyfish known as the Cassiopea. Fortunately, the most common jellyfish in the Florida Keys, the Cassiopeas (Cassiopea fronosa or Cassiopea xamachana) tend to give only a mild sting.

Get the latest news from the Aquarium by email! The collection of different types varies from species to species, and may even change throughout their lifetime. Despite the very close co-operation the zooxanthellae are not transmitted vertically but are taken up from the water column during the polyp stage. Photoaccumulative or photoprotective functions of host pigments, as proposed for some scleractinian corals, thus seem unlikely in the colored tentacles (vesicles) of the upside‐down jellyfish Cassiopea … Cassiopea “Upside Down Jellyfish” (called Cassiopea) is being used as a new model for symbiosis and coral bleaching. Coral Reefs 5:201–204, Hoegh-Guldberg O, Muller-Parker G, Cook C, Gates RD, Gladfelter E, Trench R, Weis V (2007a) Len Muscatine (1932–2007) and his contributions to the understanding of algal-invertebrate endosymbiosis. Fortunately, the most common jellyfish in the Florida Keys, the Cassiopeas (Cassiopea fronosa or Cassiopea xamachana) tend to give only a mild sting. In other cnidarian-zooxanthellae partnerships these conditions would lead to a severe disturbance of the symbiosis often ultimately leading to the death of the holobiont (bleaching). Although the Greek goddess is usually spelled Cassiopeia and the jellyfish is always spelled Cassiopea. As their name suggests, they are upside-down (relative to typical jellies).

The upside-down jellyfish Cassiopea is a benthic scyphozoan, considered a non-indigenous invasive species in the Mediterranean, forming large blooms in eutrophic areas.

The upside-down jellyfish, Cassiopea xamachana, which lives in the Carribbean, Hawaii and Florida, appears as a flower on the seafloor and tends to aggregate in large groups. Some of the most fascinating and outstanding mysteries related to the genomic underpinnings of metazoan biology are centered around cnidarians [1]. Zooxanthellae is an algae that is symbiotic to the corals and jellyfish that absorb sunlight and photosynthesize it into energy for the animals. Jellies are classified in Phylum Cnidaria (which includes anemones and corals) and the clade Medusozoa. This unique quality has earned them the nickname of 'upside-down jellyfish'.
