Cyanea Fulva
''Cyanea fulva'', the Atlantic lion's mane jellyfish, is a species of jellyfish found along the Mid-Atlantic coastal region of the United States. ''C. fulva'' are commonly noted as being about two inches in diameter and smaller than ''C. capillata'', however, larger than ''C. versicolor'', a co-occurring close species. One distinctive feature present in mature ''C. fulva'' populations is their four mouth-part tentacles, containing a cinnamon color with the center of the main cavity being darker. At a young age, these jellyfish can have three appendages but often gain a fourth at more developed life cycle stages. ''C. fulva'' are also known for having less folds compared to ''C. arctica'' but more folds compared to ''C. versicolor''. These folds are described as being remarkably thin and deciduous. Their distribution is commonly associated with regions south of Cape Cod and in the Long Island Sound. ''C. fulva'' demonstrate a peak in their population during the middle of summer and ...

Medusae Of World-vol03 Pl66 Cyanea Capillata Fulva
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 locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary 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, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in ...

Cyaneidae
The Cyaneidae are a family of true jellyfish. About 20 species are in this family, including the well-known lion's-mane jellyfish. Species The following species are recognized within the family Cyaneidae. Formerly, this family also included the genus ''Drymonema''. The Cyaneidae species do not possess any internal organs, ganglia, or any other nerve cells. They do, however, possess gap junctions between neurons which allow for complex reactive behavior and swimming actions. * Genus '' Cyanea'' Péron & Lesueur, 1810 **'' Cyanea annaskala'' von Lendenfeld, 1884 **''Cyanea buitendijki'' Stiasny, 1919 **''Cyanea capillata'' (Linnaeus, 1758) **''Cyanea citrae'' (Kishinouye, 1910) **'' Cyanea ferruginea'' Eschscholtz, 1929 **'' Cyanea lamarckii'' Péron & Lesueur, 1809 **'' Cyanea nozakii'' Kishinouye, 1891 **'' Cyanea postelsi'' Brandt, 1838 **'' Cyanea purpurea'' Kishinouye, 1910 **'' Cyanea rosea'' Quoy & Gaimard 1824 * Genus '' Desmonema'' L.
