Cassiopea
''Cassiopea'' (upside-down jellyfish) is a genus of true jellyfish and the only members of the family Cassiopeidae. They are found in warmer coastal regions around the world, including shallow mangrove swamps, mudflats, canals, and turtle grass flats in Florida, and the Caribbean and Micronesia. The medusa usually lives upside-down on the bottom, which has earned them the common name. These jellyfish partake in a symbiotic relationship with photosynthetic dinoflagellates and therefore, must lie upside-down in areas with sufficient light penetration to fuel their energy source. Where found, there may be numerous individuals with varying shades of white, blue, green and brown. Species According to the ''World Register of Marine Species'', this genus includes 8 species: * ''Cassiopea andromeda'' (Forsskål, 1775) * '' Cassiopea depressa'' Haeckel, 1880 * '' Cassiopea frondosa'' (Pallas, 1774) * ''Cassiopea maremetens'' Gershwin, Zeidler & Davie, 2010 * '' Cassiopea medusa'' ...

Cassiopea Ornata
''Cassiopea ornata'' are one of many Cnidarian species called the upside-down jellyfish. This pelagic jellyfish primarily lives in tropical waters, off the coast of Australia in shallow lagoons and around mangrove trees. The name "upside-down jellyfish" comes from the fact that it appears to be upside-down in its natural state—resting on its bell. Its bell is a golden/brown color and the tentacles vary with different shades of yellow. While the sighting of this particular species is rare, it is usually mistaken for vegetation like the other species in genus ''Cassiopea''. Reproduction ''Cassiopea ornata'' are a part of the class, Scyphozoa, "the true jelly-fish." Members of this class are gonochoric. As a cnidarian, the cassiopea ornata jellyfish can reproduce both sexually and asexually. When in a medusa form, it will reproduce sexually. The male will produce sperm and release them into the water, while the female produces eggs and keeps them in order to obtain the males spe ...

Cassiopea Xamachana
''Cassiopea xamachana'', commonly known as the upside-down jellyfish, is a species of jellyfish in the family Cassiopeidae. It is found in warm parts of the western Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. It was first described by the American marine biologist Henry Bryant Bigelow in 1892. Description The medusa phase of ''Cassiopea xamachana'' can grow to a diameter of about . Compared to most species of jellyfish it is upside-down, that is to say the bell, which is saucer-shaped, is underneath and acts like a suction cup to stabilise the jellyfish on the seabed. The four pairs of much-branched tentacles are on the upperside. Instead of a central mouth, there are numerous oral openings in the tentacles which connect via channels to the stomach. The mesogloea, the jelly-like tissue, contains symbiotic zooxanthellae, single-celled protists, which are photosynthetic and give the jellyfish its variable color, often bluish-grey or bluish-green.

Cassiopea Andromeda
''Cassiopea andromeda'' is one of many cnidarian species called the upside-down jellyfish. It usually lives in intertidal sand or mudflats, shallow lagoons, and around mangroves. This jellyfish, often mistaken for a sea anemone, usually keeps its mouth facing upward. Its yellow-brown bell, which has white or pale streaks and spots, pulsates to run water through its arms for respiration and to gather food. Alimentation and strategies ''Cassiopea andromeda'' is carnivorous and eats small animals from the sea or just pieces of them after it paralyzes its prey with its mucus and nematocysts when they are released. This jellyfish also lives in a symbiotic relationship with photosynthetic dinoflagellate algae, the zooxanthellae Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs. Most known zooxanthellae are in the genus ''S ..., and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medusa (biology)
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 coa ...

Zooxanthellae
Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs. Most known zooxanthellae are in the genus ''Symbiodinium'', but some are known from the genus '' Amphidinium'', and other taxa, as yet unidentified, may have similar endosymbiont affinities. The true ''Zooxanthella'' K.brandt is a mutualist of the radiolarian ''Collozoum inerme'' (Joh.Müll., 1856) and systematically placed in Peridiniales. Another group of unicellular eukaryotes that partake in similar endosymbiotic relationships in both marine and freshwater habitats are green algae zoochlorellae. Zooxanthellae are photosynthetic organisms, which contain chlorophyll a and chlorophyll c, as well as the dinoflagellate pigments peridinin and diadinoxanthin. These provide the yellowish and brownish colours typical of many of the host species. During the day, they provide their host ...
