Pelagiidae
The Pelagiidae are a family of jellyfish. Members of the family ''Pelagiidae'' have no ring canal, and the marginal tentacles arise from umbrella margin. Genera There are four genera currently recognized: *Genus '' Chrysaora'' – (14 species) *Genus '' Mawia'' – '' Mawia benovici'' *Genus ''Pelagia Pelagia (), distinguished as Pelagia of Antioch, Pelagia the Penitent, and Pelagia the Harlot, was a Christian saint and hermit in the 4th or 5th century.

Mawia
''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.Avian, M.; Ramšak, A.; Tirelli, V.; D'ambra, I.; Malej, A.

''Invertebrate Systematics.'' 30(6), 523-546. 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 Senegal, officially the Republic of Senegal, is the westernmost country in West Africa, situated on the ...

Pelagia (genus)
''Pelagia noctiluca'' is a jellyfish in the family Pelagiidae and the only currently recognized species in the genus ''Pelagia''. It is typically known in English as the mauve stinger, but other common names are purple-striped jelly (causing potential confusion with '' Chrysaora colorata''), purple stinger, purple people eater, purple jellyfish, luminous jellyfish and night-light jellyfish. In Greek, ''pelagia'' means "(she) of the sea", from ''pelagos'' "sea, open sea"; in Latin ''noctiluca'' is the combining form of ''nox'', "night", and ''lux'', "light"; thus, ''Pelagia noctiluca'' can be described as a marine organism with the ability to glow in the dark (bioluminescence). It is found worldwide in tropical and warm temperate seas, although it is suspected that records outside the North Atlantic region, which includes the Mediterranean and Gulf of Mexico, represent closely related but currently unrecognized species. A fairly small and variably coloured species, both its tentac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysaora
''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'' - Southern African Sea Nettle * '' Chrysaora agulhensis'' - Agulhas Sea Nettle * '' Chrysaora chesapeakei'' - bay nettle * '' Chrysaora chinensis'' * '' Chrysaora colorata'' – purple-striped jelly * '' Chrysaora fulgida'' - Benguela Compass Jelly * ''Chrysaora fuscescens'' – Pacific sea nettle * '' Chrysaora helvola'' * '' Chrysaora hysoscella'' – compass jellyfish * '' Chrysaora lactea'' - Milk Sea Nettle * ''Chrysaora melanaster'' – northern sea nettle * '' Chrysaora pacifica'' – Japanese sea nettle * '' Chrysaora pentast ...

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, larvacean Larvaceans, copelates or append ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jellyfish
Jellyfish, also known as sea jellies or simply jellies, are the #Life cycle, medusa-phase of certain gelatinous members of the subphylum Medusozoa, which is a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals, although a few are anchored to the seabed by stalks rather than being motile. They are made of an umbrella-shaped main body made of mesoglea, known as the ''bell'', and a collection of trailing tentacles on the underside. Via pulsating contractions, the bell can provide propulsion for animal locomotion, locomotion through open water. The tentacles are armed with cnidocyte, stinging cells and may be used to capture prey or to defend against predators. Jellyfish have a complex biological life cycle, life cycle, and the medusa is normally the sexual phase, which produces planula larvae. These then disperse widely and enter a sedentary #Life cycle, polyp phase which may include asexual budding before reaching sexual maturity. Jellyfish ...

Cnidarian Families
Cnidaria ( ) is a phylum under kingdom Animalia containing over 11,000 species of aquatic invertebrates found both in freshwater and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites. Their distinguishing features are an uncentralized nervous system distributed throughout a gelatinous body and the presence of cnidocytes or cnidoblasts, specialized cells with ejectable flagella used mainly for envenomation and capturing prey. Their bodies consist of mesoglea, a non-living, jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians are also some of the few animals that can reproduce both sexually and asexually. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes, which are specialized stinging cells used to capture ...
