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 Cyanea may refer to: * ''Cyanea'' (jellyfish), a genus of jellyfish in the family Cy ...

Semaeostomeae
Semaeostomeae (literally "flag mouths") is an order of large jellyfish characterized by four long, frilly oral arms flanking their quadrate mouths. The umbrella is domed with scalloped margins, and the gastrovascular system consists of four unbranched pouches radiating outwards from the central stomach; no ring canal is present. They usually possess eight tentacles; four are per-radical and four are inter-radical. Taxonomy The order consists of five families. * Family Cyaneidae * Family DrymonematidaeBayha, K. M., and M. N.

Desmonema (jellyfish)
''Desmonema'' is a genus of jellyfish under the Cyaneidae family found in colder waters near the Antarctic region and off of the coast of Argentina. They have a bell diameter that can extend over 1 meter and wide tentacles that are grouped together in clusters. They share similar anatomical and physiological structures to the genus '' Cyanea''. Their sophisticated structures like the thick tentacles, sensory systems, and gastrovascular system allow ''Desmonema'' to easily capture and extracellularly digest their prey. In recent years, ''Desmonema'' were reported to have a commensal relationship with fishes under the ''Trachurus'' genus and a parasitic relationship with specimens of the '' Hyperia'' genus. Anatomy The anatomical structure of ''Desmonema'' closely resembles that of the genus '' Cyanea''. ''Desmonema'' tend to have a wider bell diameter between 20 and 100 centimeters compared to other Scyphozoans. They have a strong, well-developed radial and circular arrangement ...

Cyanea Annaskala
''Cyanea annaskala'' is a species of jellyfish that was discovered in 1882 by Robert Lendlmayer von Lendenfeld. Phylogeny ''Cyanea annaskala'' is in the scyphozoan class of the phylum Cnidaria. The scyphozoans are the true jellies. It is within the order Semaeostomeae. The Semaeostomeae are the flag mouth jellies. It is within the family Cyaneidae, which contain the better known species of the lion's mane jellyfish. The phylogeny of the Lion's mane jellyfish has long been debated since their discovery, and the ''Cyanea Annaskala'' has long been implicated in this difficulty. The high proportion of cosmopolitan species in pelagic individuals makes it extremely tedious to differentiate between closely related members. Because of limited study and challenging experimentation, not all of the ''Cyanea'' species from the North Atlantic are considered valid. Protein and medusae analysis from Michael N. Dawson of the University of New South Wales confirm that ''Cyanea Annaskala'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanea (jellyfish)
''Cyanea'' is a genus of jellyfish, primarily found in northern waters of the Atlantic and Pacific Oceans and southern Pacific waters of Australia and New Zealand, there are also several boreal, polar, tropical and sub-tropical species. Commonly found in and associated with rivers and fjords. The same genus name has been given to a genus of plants of the Hawaiian lobelioids, an example of a ''parahomonym'' (same name, different kingdom). Species The taxonomy of ''Cyanea'' species has seen increased scrutiny in recent years.Dawson MN. 2005.

Cyanea Lamarckii
''Cyanea lamarckii'', also known as the blue jellyfish or bluefire jellyfish, is a species of jellyfish in the family Cyaneidae. Description Blue jellyfish age can be identified by color of their bell. They tend to be pale in appearance when young, but mature to have a brightly purple-blue (some yellow) colored bell. Although it is similar to the lion's mane jellyfish, the blue jellyfish is not as large, and has a translucent bell. ''C. lamarckii'' has a blue or yellow tone and grows to approximately across, but specimens can grow to . In Scandinavian seas, this species rarely grows larger than . These jellyfish drift closer to the shore to catch the large abundance of plankton with their tentacles. This jellyfish has many stinging tentacles. The four mouth arms are large with many wrinkles and ripples. The jellyfish live off a diet of phytoplankton or zooplankton as well as the eggs and larvae of other aquatic animals such as fish. ''Cyanea lamarkii'' use their tentacles c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lion's Mane Jellyfish
The lion's mane jellyfish (''Cyanea capillata''), also known as the giant jellyfish, arctic red jellyfish, or the hair jelly, is one of the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans. It is common in the English Channel, Irish Sea, North Sea, and in western Scandinavian waters south to Kattegat and Øresund. It may also drift into the southwestern part of the Baltic Sea (where it cannot breed due to the low salinity). Similar jellyfish – which may be the same species – are known to inhabit seas near Australia and New Zealand. The largest recorded specimen was measured off the coast of Massachusetts in 1865 and had a bell with a diameter of and tentacles around long. Lion's mane jellyfish have been observed below 42°N latitude for some time in the larger bays of the East Coast of the United States. The lion's mane jellyfish uses its stinging tentacles to capture, pull in, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
