Periphyllopsis is a genus of deep-sea crown jellyfish in the family Periphyllidae . [1]
According to the World Register of Marine Species, Periphyllopsis contains two accepted species: [2] [3]
Periphyllidae is a family of jellyfish containing four genera and six species. The most well-known member of the family, Periphylla periphylla, is usually considered a deep-sea species, but it forms large blooms in surface waters of Norwegian fjords.
Chrysaora is a genus of jellyfish, commonly called the sea nettles, in the family Pelagiidae. The origin of the genus name Chrysaora lies in Greek mythology with Chrysaor, brother of Pegasus and son of Poseidon and Medusa. Translated, Chrysaor means "he who has a golden armament."
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.
Cassiopea andromeda is one of many cnidarian species called the upside-down jellyfish. It usually lives in intertidal sand or mudflats, shallow lagoons, and around mangroves. This jellyfish, often mistaken for a sea anemone, usually keeps its mouth facing upward. Its yellow-brown bell, which has white or pale streaks and spots, pulsates to run water through its arms for respiration and to gather food.
Ernst Vanhöffen was a German zoologist.
Haliscera is a genus of hydrozoans in the family Halicreatidae.
Colobonema is a genus of deep-sea hydrozoans.
Arctapodema is a genus of deep-sea hydrozoans in the family Rhopalonematidae.
Rhopalonema is a genus of deep-sea hydrozoans of the family Rhopalonematidae.
Chrysaora africana, the purple compass jelly, is a species of jellyfish from the family Pelagiidae. Found in the southeastern Atlantic Ocean from Gabon to the western coast of South Africa, its taxonomy has historically caused considerable confusion. Like other sea nettles, its sting is painful, but not generally dangerous unless there is an allergic reaction to the venom.
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.
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.
Nausithoe is a genus of jellyfishes belonging to the family Nausithoidae.
Atolla chuni is a species of crown jellyfish within the family Atollidae. The species is found distributed in the Southern Ocean and some parts of the southern Pacific and Atlantic Ocean in pelagic environments at depths of up to 5198 meters. Individuals have been found with partially digesting remains of large Calanoida copepods, chaetognaths, Hyperiidea amphipods, and krill attached to the gastric cirri. It grows to a length of 7 centimeters.
Spiromanes is a genus of millipedes in the family Pachybolidae.
Periphyllopsis braueri is a red-colored jellyfish of the deep sea, belonging to the order Coronatae of the phylum Cnidaria. It is one of two species in the genus Periphyllopsis. It has only been documented ~18 times because of the depth that it resides at, and inhabits areas off the coast of Florida and Japan.
Atolla valdiviae is a species of true jellyfish in the family Atollidae. It is known from type specimens found in the north Pacific Ocean.
Nausithoe clausi is a species of crown jellyfish in the family Nausithoidae. The species has been observed in the Western Central Pacific, and are ~0.9 centimeters wide.
Nausithoe rubra is a species of crown jellyfish in the family Nausithoidae. Adult medusa are believed to grow up to ~15 millimeters in size, and the species may be distributed worldwide. Species is confirmed to be in the East Atlantic, but may also reside in other oceans.
Atorella subglobosa is a species of crown jellyfish in the family Atorellidae. The species was collected from marine waters near Indonesia during the Siboga expedition and described by Ernst Vanhöffen in 1902.
