Clytia (hydrozoan)
''Clytia'' is a genus of hydrozoans belonging to the family Campanulariidae. The genus has cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext ....

Hydrozoans
Hydrozoa (hydrozoans; ) are a taxonomic class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genera within this class live in freshwater habitats. Hydrozoans are related to jellyfish and corals and belong to the phylum Cnidaria. Some examples of hydrozoans are the freshwater jelly (''Craspedacusta sowerbyi''), freshwater polyps ('' Hydra''), ''Obelia'', Portuguese man o' war (''Physalia physalis''), chondrophores (Porpitidae), "air fern" (''Sertularia argentea''), and pink-hearted hydroids (''Tubularia''). Anatomy Most hydrozoan species include both a polypoid and a medusoid stage in their lifecycles, although a number of them have only one or the other. For example, ''Hydra'' has no medusoid stage, while '' Liriope'' lacks the polypoid stage. Polyps The hydroid f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''.

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Clytia Ambigua
In Greek mythology, the name Clytie (Ancient Greek: Κλυτίη, Ionic) or Clytia (, Attic and other dialects) may refer to: *Clytie (Oceanid), known for her unrequited love for Helios. Out of jealousy, Clytie arranged the death of Leucothoe, Helios' lover. *Clytie, daughter of Pandareus and sister of Cameiro. Cameiro and Clytie lost their parents to the wrath of gods and were reared by Aphrodite. They received gifts from other Olympic goddesses as well: wisdom and beauty from Hera, high stature from Artemis, skill in handiwork from Athena. When Aphrodite left for Olympus to arrange for the sisters to get happily married in the future, the girls, left without supervision, were abducted by the Harpies and given by them to the Erinyes. *Clytie, daughter of Merops, wife of Eurypylus of Cos, mother of Chalcon and Antagoras. She received Demeter as guest. *Clytie, daughter of Amphidamas and possible mother of Pelops by Tantalus. Robert Graves. ''The Greek Myths'', section 108 (1 ...
