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. The origin of the genus name ''Chrysaora'' lies in Greek mythology with Chrysaor, brother of Pegasus and son of Poseidon and Medusa. Translated, ... in South America; '' C. lactea'' ranges along the Atlantic coast of the continent, but generally further north than ''C. plocamia''. Historically, ''C. plocamia'' was often confused with '' C. hysoscella'', a species now known to be restricted to the northeast Atlantic. ''C. plocamia'' is a large jellyfish, up to in bell diameter, although most mature individuals only are . Reproduction The South ...

Monterey Bay Aquarium
Monterey Bay Aquarium is a nonprofit public aquarium in Monterey, California. Known for its regional focus on the marine habitats of Monterey Bay, it was the first to exhibit a living kelp forest when it opened in October 1984. Its biologists have pioneered the animal husbandry of jellyfish and it was the first to successfully care for and display a great white shark. The organization's research and conservation efforts also focus on sea otters, various birds, and tunas. Seafood Watch, a sustainable seafood advisory list published by the aquarium beginning in 1999, has influenced the discussion surrounding sustainable seafood. Early proposals to build a public aquarium in Monterey County were not successful until a group of four marine biologists affiliated with Stanford University revisited the concept in the late 1970s. Monterey Bay Aquarium was built at the site of a defunct sardine cannery and has been recognized for its architectural achievements by the American Institut ...

Jellyfish
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. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient animal locomotion, locomotion. The tentacles are armed with Cnidocyte, stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex Biological life cycle, life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp (zoology), polyp phase before reaching sexual maturity. Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine habitats, marine, but some hydrozoans with a simila ...

Tierra Del Fuego
Tierra del Fuego (, ; Spanish for "Land of the Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands. The southernmost extent of the archipelago is just north of latitude 56°S. The earliest known human settlement in Tierra del Fuego dates to approximately 8,000 BC. Europeans first explored the islands during Ferdinand Magellan's expedition of 1520. ''Tierra del Fuego'' and similar namings stem from sightings of the many bonfires that the natives built. Settlement by those of European descent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Nettle
''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 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. ''C. hysoscella'' contribute to the global issue of jellyfish overpopul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
