Sea Nettles
''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." Species There are 16 recognized species in the genus ''Chrysaora'': * '' Chrysaora achlyos'' – black sea nettle * '' Chrysaora africana'' * ''Chrysaora agulhensis'' * ''Chrysaora chesapeakei'' - Atlantic bay nettle * '' Chrysaora chinensis'' * ''Chrysaora colorata'' – purple-striped jelly * ''Chrysaora fulgida'' * ''Chrysaora fuscescens'' – Pacific sea nettle * ''Chrysaora helvola'' * ''Chrysaora hysoscella'' – compass jellyfish * ''Chrysaora lactea'' * ''Chrysaora melanaster'' – northern sea nettle * ''Chrysaora pacifica'' – Japanese sea nettle * ''Chrysaora pentastoma'' * ''Chrysaora plocamia'' – South American sea nettle * ''Chrysaora quinquecirrha Th ...

Chrysaora Fuscescens
The Pacific sea nettle (''Chrysaora fuscescens''), or West Coast sea nettle, is a common Plankton, planktonic scyphozoan that lives in the eastern Pacific Ocean from Canada to Mexico. Sea nettles have a distinctive golden-brown bell with a reddish tint. The bell can grow to be larger than one meter (three feet) in diameter in the wild, though most are less than 50 cm across. The long, spiraling, white oral arms and the 24 undulating maroon tentacles may trail behind as far as 15 feet (4.6 m). For humans, its sting is often irritating, but rarely dangerous. ''Chrysaora fuscescens'' has proven to be very popular for display at public aquariums due to their bright colors and relatively easy maintenance. It is possible to establish polyps and culture ''Chrysaora'' in captivity. When provided appropriate aquarium conditions, the medusae do well under captive conditions. Taxonomy Johann Friedrich von Brandt described this species in 1835. The origin of the genus name ''Chrysaora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysaora Quinquecirrha
The Atlantic sea nettle (''Chrysaora quinquecirrha''), also called the East Coast sea nettle in the United States, is a species of jellyfish that inhabits the Atlantic coast of the United States. Historically it was confused with several ''Chrysaora'' species, resulting in incorrect reports of ''C. quinquecirrha'' from other parts of the Atlantic and other oceans. Most recently, '' C. chesapeakei'' of estuaries on the Atlantic coast of the United States, as well as the Gulf of Mexico, was only fully recognized as separate from ''C. quinquecirrha'' in 2017. It is smaller than the Pacific sea nettle, and has more variable coloration, but is typically pale, pinkish or yellowish, often with radiating more deeply colored stripes on the exumbrella, especially near the margin. Description The medusae of ''C. quinquecirrha'' measures up to in diameter. The sea nettle is radially symmetrical, marine, and carnivorous. Its mouth is located at the center of one end of the body, which ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysaora Plocamia
The South American sea nettle (''Chrysaora plocamia'') is a species of jellyfish from the family Pelagiidae. It is found from the Pacific coast of Peru, south along Chile's coast to Tierra del Fuego, and north along the Atlantic coast of Argentina, with a few records from Uruguay. Despite its common name, it is not the only sea nettle ''Chrysaora'' () is a genus of jellyfish, commonly called the sea nettles, in the family Pelagiidae.

Chrysaora Pentastoma
''Chrysaora pentastoma'' is a species of jellyfish from the family Pelagiidae. This small sea nettle has a strong sting and it is found in coastal waters of eastern South Australia. Taxonomy ''C. pentastoma'' was described in 1810. Its original description is limited and in 2008 it was argued that it is insufficient for recognizing it, making the name a ''nomen dubium''. Instead the authors described three Southern Australian species in 2008: ''C. kynthia'', ''C. southcotti'' and ''C. wurlerra''. In 2010, this was disputed in a review of all ''Chrysaora'' species, which noted that ''C. pentastoma'' has a unique colour pattern that is described in its original description from 1810 and this is sufficient for recognizing it, making ''C. southcotti'' its junior synonym. ''C. kynthia'' from southwestern Australia and ''C. wurlerra'' from New South Wales were described in 2008 based mainly on colour, their tentacles and details of their gonad shape, but these can be variable in ''Chry ...

Chrysaora Pacifica
''Chrysaora pacifica'', commonly named the Japanese sea nettle, is a jellyfish in the family Pelagiidae. This common species is native to the northwest Pacific Ocean, including Japan and Korea, but it was formerly confused with the larger and more northerly distributed '' C. melanaster''. As a consequence, individuals kept in public aquariums have often been mislabelled as ''C. melanaster''. The medusae Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria.

Chrysaora Melanaster
''Chrysaora melanaster'', commonly known as the northern sea nettle or brown jellyfish, is a species of jellyfish native to the northern Pacific Ocean and adjacent parts of the Arctic Ocean. It is sometimes referred to as a Pacific sea nettle, but this name is also used for '' C. fuscescens''; the name Japanese sea nettle was also used for this species, but that name now exclusively refers to '' C. pacifica''. Although jellyfish kept in public aquariums sometimes are referred to as ''C. melanaster'', this is the result of the historical naming confusion and these actually are ''C. pacifica''. Description The medusa of the northern sea nettle can reach in diameter with tentacles growing up to .CNET newsChrysaora melanaster from "Census of Marine Life reveals hidden life in oceans" article (October 5, 2010). The number of tentacles is up to 24 (three per octant). It dwells at depths of up to 100 meters, where it feeds on copepods, larvaceans, small fish, large zooplankton, and ...

Chrysaora Lactea
''Chrysaora lactea'' is a sea nettle in the family Pelagiidae. This jellyfish has a bell diameter of up to , and it is native to the Atlantic coast of South America. It has also been reported from the Caribbean region, but genetic studies indicate that this population is closer to '' C. chesapeakei''.

Chrysaora Hysoscella
''Chrysaora hysoscella'', the compass jellyfish, is a common species of jellyfish that inhabits coastal waters in temperate regions of the northeastern Atlantic Ocean, including the North Sea and Mediterranean Sea. In the past it was also recorded in the southeastern Atlantic, including South Africa, but this was caused by confusion with close relatives; '' C. africana'', '' C. fulgida'' and an undescribed species tentatively referred to as "''C. agulhensis''". It is a true jellyfish displaying radial symmetry with distinct brown markings shaped like elongated V's on its bell. ''C. hysoscella'' adults are highly susceptible to the parasite Hyperia medusarum but this hasn't had any significant effects on the population. This organism has a benthic polyp stage before developing into a pelagic adult medusae. Compass jellyfish consume a variety of marine invertebrates and plankton and are preyed on by very few.

Chrysaora Helvola
''Chrysaora helvola'' is a jellyfish in the family Pelagiidae. Although still recognized as a valid species by the World Register of Marine Species, its taxonomic history is confusing and recent reviews of the genus have not recognized it. Taxonomy '' C. fuscescens'' was described in 1835 by Johann Friedrich von Brandt and three years later he described ''C. helvola'' (a name he preferred), noting that ''C. fuscescens'' was its synonym. This is contrary to the ICZN Code, which states that the oldest name must be used (the younger becomes a junior synonym), but Brandt's publications resulted in confusion and it was only in the 1980s that ''C. fuscescens'' again was recognized as a valid species. Nevertheless, the long history of the name ''C. helvola'' means that it still appears, although recent reviews of the genus have not recognized it.

Chrysaora Fulgida
''Chrysaora fulgida'', the Benguela compass jelly, is a species of jellyfish in the family Pelagiidae. Found in the southeastern Atlantic Ocean along the western coast of South Africa (an area affected by the Benguela Current), its Taxonomy (biology), 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. Taxonomy ''C. fulgida'' was first described in 1830 by A.A.M. Reynaud. In 1902, ''Chrysaora africana, C. africana'' was described by Ernst Vanhöffen, E. Vanhöffen. In 1939 it was suggested that ''C. africana'' simply represented old individuals of ''C. fulgida'', a view repeated as recently as 2010. ''C. fulgida'' itself has frequently been confused with the closely related and quite similar ''Chrysaora hysoscella, C. hysoscella''. Recent studies have been able to separate not only ''C. hysoscella'' (now known to be restricted to the northeast Atlantic ...
