Campanulariidae
Campanulariidae is a family of animals in the phylum Cnidaria, or stinging-celled animals. Campanulariidae is composed entirely of hydroids, a Greek term meaning "water animals" applied to the plant-like polyp colonies of the class Hydrozoa. All species of the Campanulariidae are aquatic in habitat, primarily inhabiting coastal regions and tidal pools. ''Obelia'' contains probably the most well-known species of this phylum, and include four species. All are around 20–35 cm in height with a series of branches carrying the individual polyps. One species, ''Obelia longissima'', is unique for its ability to produce obelin, a photoprotein which allows for bioluminescence. The genus '' Laomedea'' includes such species as '' Laomedea angulata'' and '' Laomedea flexuosa'', which are similar in appearance to the ''Obelia'', though they are smaller and lack a medusa stage present in ''Obelia''.

Obelia
''Obelia'' is a genus of hydrozoans, a class of mainly marine and some freshwater animal species that have both polyp and medusa stages in their life cycle. Hydrozoa belongs to the phylum Cnidaria, which are aquatic (mainly marine) organisms that are relatively simple in structure with a diameter around 1mm. There are currently 120 known species, with more to be discovered. These species are grouped into three broad categories: ''O. bidentada'', ''O. dichotoma'', and ''O. geniculata''. ''O. longissima'' was later accepted as a legitimate species, but taxonomy regarding the entire genus is debated over. ''Obelia'' is also called sea fur. ''Obelia'' has a worldwide distribution except the high-Arctic and Antarctic seas. and a stage of ''Obelia'' species are common in coastal and offshore plankton around the world.Cornelius, P.F.S., 1995b.

Laomedea Flexuosa
''Laomedea flexuosa'' is a species of cnidarians belonging to the family Campanulariidae. It is native to Europe and Northern America Northern America is the northernmost subregion of North America. The boundaries may be drawn slightly differently. In one definition, it lies directly north of Middle America (including the Caribbean and Central America).Gonzalez, Joseph. 20 ....

Clytia Gregaria
''Clytia gregaria'', sometimes referred to as the gregarious jellyfish, is a small species of hydrozoan in the family Campanulariidae. It is one of the most abundant hydrzoans of the Pacific Northwest, particularly during late spring and summer. Range and Habitat ''Clytia gregaria'' is found on the eastern Pacific Ocean, from Alaska to Oregon. It is pelagic and commonly found floating close to shore. Description Mature individuals can reach 2 cm in diameter, but rarely reach 1.5 cm. ''Clytia gregaria's'' translucent bell is saucer-shaped, with a diameter greater than its height. Positioned close to the bell margin are four radial canals with a white or yellowish elongated gonad in each. On the bell margin are up to 60 highly extensile tentacles of equal length (in mature individuals). The mouth opens directly into the manubrium, which has four ruffled lips and is a pale yellow or brownish color. The manubrium is attached directly to the subumbrella. Sometime ...

Obelia Longissima
''Obelia longissima'' is a colonial species of hydrozoan in the order Leptomedusae. Its hydroid form grows as feathery stems resembling seaweed from a basal stolon. It is found in many temperate and cold seas world-wide but is absent from the tropics. Description The sessile colonial stage of ''Obelia longissima'' is the most long-lived and the most easily observed of its life stages. The hydroid looks superficially like fronds of seaweed. It has a basal stolon growing in close proximity with the substrate. Out of this grow fragile, flexible stems up to high each with short side branches. As the stolon grows, new branches develop and the older ones are reabsorbed so the colony moves across the substrate. When the availability of food is high, further upright branches develop but when it is low, most growth takes place by way of stolon elongation and branching. The stems have dark-coloured, usually straight internodes between chitinous chambers called hydrothecae which are shape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
