Cassiopea (upside-down jellyfish) is a genus of true jellyfish in the family Cassiopeidae. They are found in warmer coastal regions around the world, including shallow mangrove swamps, mudflats, canals, and turtle grass flats in Florida, the Caribbean and Micronesia. The medusa usually lives upside-down on the sea floor in shallow areas, which has earned them their common name. They have a symbiotic relationship with photosynthetic dinoflagellates and therefore must lie upside-down in areas with sufficient light. Where found, there may be numerous individuals with varying shades of white, blue

Rhizostoma is a genus of medium to large rhizostomatid jellyfish found in the East Atlantic Ocean (North Sea and British Isles to South Africa) and Mediterranean Sea.

Rhopilema is a genus of jellyfish.

Cotylorhiza is a genus of true jellyfish from the family Cepheidae. The genus is found in the central-east Atlantic, Mediterranean, and western Indian Ocean.

Atolla is a genus of crown jellyfish in the order Coronatae. The genus Atolla was originally proposed by Haeckel in 1880 and elevated to the monotypic family level, as Atollidae by Henry Bigelow in 1913. The six known species inhabit the mesopelagic zone. The medusae possess multiple lobes called lappets at the bell margin. Medusae also have eight tentacles, alternating with eight rhopalia, and twice as many lappets occur as tentacles.

Catostylus is a genus of jellyfish in the family Catostylidae.

Stomolophus is a genus of true jellyfish from the West Atlantic and Pacific. It is the only genus in the monotypic family Stomolophidae. Formerly, Nomura's jellyfish (Nemopilema nomurai) was also included in this genus, but has now been reclassified to the family Rhizostomatidae.

Deepstaria is a genus of jellyfish known for their thin, sheet-like bodies. The genus is named after the Deep Star 4000, which collected the holotype of the type species, D. enigmatica.

Stygiomedusa gigantea, commonly known as the giant phantom jelly, is the only known species in the monotypic genus of deep sea jellyfish, Stygiomedusa. It is in the Ulmaridae family. With only around 118 sightings in 110 years, it is a jellyfish that is rarely seen, but believed to be widespread throughout the world, with the exception of the Arctic Ocean.

Crambione is a genus of jellyfish in the family Catostylidae.

Pseudorhiza is a genus of cnidarians belonging to the family Lychnorhizidae.

Phyllorhiza is a genus of jellyfish in the family Mastigiidae.

Crambionella is a genus of Cnidarians belonging to the family Catostylidae. The genus is distinguishable from other Castostylid species by a terminal club on each oral arm without filaments and a canal system featuring a narrow, wide-meshed intra-circular network of interconnected vessels. These vessels solely communicate with the ring canal and not with the radial canals. Four species belong to the genus Crambionella (Stiasny, 1921): C. annandalei (Rao, 1931), C. helmbiru (Nishikawa, Mulyadi & Ohtsuka, 2014), C. orsini (Vanhöffen, 1888) and C. stuhlmanni (Chun, 1896). C. orsini is the type sp

Mastigias is a genus of true jellyfish in the family Mastigiidae. It contains eight recognized species. Members of this genus are found widely in coastal regions of the Indo-Pacific, including saline lakes of Palau (e.g., Jellyfish Lake), but there are also records from the West Atlantic at Florida and Puerto Rico. The West Atlantic records are most likely the result of accidental introductions by humans.

Lobonemoides is a genus of cnidarians belonging to the family Lobonematidae.

Lychnorhiza is a genus of jellyfish in the family Lychnorhizidae.

Linuche is a genus of cnidarians belonging to the family Linuchidae.

Atorella is a genus of crown jellyfish. It is the only genus in the monotypic family Atorellidae and includes five species. Members of this family are known from the eastern coast of Africa and the western coast of Panama.

Diplulmaris is a genus of jellyfish in the family Ulmaridae that contains two species, Diplulmaris antarctica and Diplulmaris malayensis. It lives in the deep water of southwest Atlantic and southern oceans in pelagic and polar marine environments. Its depth ranges from 0 meters at the surface to around 500 meters. It is 4.2 cm wide.

Cephea is a genus of true jellyfish in the family Cepheidae. They are found in the Indo-Pacific and eastern Atlantic oceans. They are sometimes called the crown jellyfish, but this can cause confusion with the closely related genus Netrostoma or the distantly related species in the order Coronatae. They are also sometimes called the cauliflower jellyfish because of the cauliflower-looking form on top of its bell.

Netrostoma is a genus of true jellyfish in the family Cepheidae. They are found in the Indo-Pacific. They are sometimes called crown jellyfish, but this can cause confusion with the closely related genus Cephea or the distantly related species in the order Coronatae.

Paraphyllina is a genus of crown jellyfish. It is the only genus in the monotypic family Paraphyllinidae, and includes three species.

Mawia is a genus of jellyfish in the family Pelagiidae. It is a monotypic genus with the sole species Mawia benovici. The team who discovered this jellyfish named it benovici after a late colleague, Adam Benovic. Originally belonging to the genus Pelagia, it was later moved into its own genus, which was named after the Arab warrior-queen Mavia. Although described based on specimens from the Adriatic Sea, a part of the Mediterranean, it was speculated that these might be transplants (via ballast water) rather than a part of its natural range. A later study found specimens in Senegal, indicating

Periphyllopsis is a genus of deep-sea crown jellyfish in the family Periphyllidae.

Drymonema is a genus of true jellyfish, placed in its own family, the Drymonematidae. There are three species: Drymonema dalmatinum, Drymonema gorgo, and Drymonema larsoni, which are found in the Gulf of Mexico, Atlantic Ocean and Mediterranean Sea.

Sanderia is a genus of jellyfish in the family Pelagiidae. There are two species recognized.

Discomedusa is a genus of jellyfish in the family Ulmaridae.

Ulmaris is a genus of jellyfish in the family Ulmaridae.

Poralia is a genus of jellyfish in the family Ulmaridae. It is a monotypic genus containing a single species, Poralia rufescens. This jellyfish is pelagic, and is found in deep water in most of the world's oceans.
