Cassiopea is a genus of scyphozoan jellyfish very commonly found in shallow mangrove swamps, mudflats, and turtle grass flats in Florida and various other similar environments around the world, where it lives usually upside-down on the bottom. The symbiosis seems mutual and both partners have adapted to suit the partner’s needs. Given its life style, it does not look like the typical jellyfish, appearing as a greenish gray-blue flower on the seafloor. Cassiosomes are stinging-cell structures in the mucus of the upside-down jellyfish Cassiopea xamachana. 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. The recently-identified culprit is the upside-down jellyfish known as the Cassiopea. Some of the most fascinating and outstanding mysteries related to the genomic underpinnings of metazoan biology are centered around cnidarians [1].

Members of the genus measure more than 100 mm (4 inches) in diameter. lives in an obligate symbiosis with its zooxanthellae: Dinoflagellates of the genus Symbiodinium. Cassiopea are found throughout the tropics in shallow ocean waters and mudflats [25, 26].They rarely swim and rather remain stationary with their bell on a surface, hence their name, the upside-down jellyfish (Figure 1B; Figure S1A; Movie S1) [25, 26].Cassiopea, like coral and sea anemones, have a photosynthetic obligate endosymbiote, Symbiodinium (Figure 1C). Bioscience 27:454–460. Jellyfish are not a clade, as they include most of the Medusozoa, barring some of the Hydrozoa. 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. One unique type of jellyfish is Cassiopea xamachana, referred to as the upside-down jellyfish. The pulsing behavior of the upside-down jellyfish, Cassiopea spp., is trackable (A) Phylogenetic tree schematic highlighting animals in which sleep behavior has been described, the presence of neurons (tan), and the emergence of a centralized nervous system (dark blue).See boxed key.

This unique quality has earned them the nickname of 'upside-down jellyfish'. This means that they, like us, are part of the kingdom Animalia. Their tentacles are upward facing, giving them a characteristic upside-down appearance. Given its life style, it does not look like the typical jellyfish, appearing as a greenish gray-blue flower on the seafloor. Zooxanthellae is an algae that is symbiotic to the corals and jellyfish that absorb sunlight and photosynthesize it into energy for the animals. pp 415-423 | Cassiopea jellyfish (Photo Credit: Peter Holderness/Caltech. The popular belief is that resting rids brain cells of toxins, helps consolidate fresh memories, and prepares the mind for a new day of learning.

The largest is the lion's mane jellyfish (Cyanea capillata), which can have a bell over six and a half feet in diameter and weigh up to 440 pounds; the smallest is the Irukandji jellyfish, several species of dangerous jellyfishes found in tropical waters, which measure only about two-tenths of an inch and weigh well under a tenth of an ounce.
