Hydrozoans
Hydrozoa (hydrozoans; from Ancient Greek ('; "water") and ('; "animals")) is 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, which also 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), and pink-hearted hydroids ('' Tubularia''). Anatomy Most hydrozoan species include both a polypoid and a medusoid stage in their life cycles, although a number of them have only one or the other. For example, ''Hydra'' has no medusoid stage, while '' Liriope'' lacks the polypoid st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladonematidae
Cladonematidae is a small family of anthomedusan hydrozoans. They have stolonal hydroid colonies, and their medusae are benthic and can crawl across the sediment; in many species they have lost the ability to swim however.Schuchert 009/ref> Several members of this lineage were formerly considered a separate family Eleutheriidae.WoRMS Description The hydranths have a circular mouth surrounded by a single whorl of adhesive tentacles which each bear a little knob at the tip; in some Cladonematidae an aboral whorl of thread-like unknobbed tentacles is also present. They have a preoral chamber formed by epidermal gland cells. The medusae bud off at the base of the hydrants, though where aboral tentacle are present these are located between the stolons and the budding sites. Cladonematidae medusae have a various extend of nematocysts around their umbrellar margin, varying between a continuous dense ring to none at all among the species. The number of radial canals and whether th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleutheria Claparedii
The Greek word "ἐλευθερία" (capitalized Ἐλευθερία; Attic Greek pronunciation: ), transliterated as eleutheria, is a Greek term for, and personification of, liberty. Eleutheria personified had a brief career on coins of Alexandria. In Ancient Greece, Eleutheria was also an epithet for the goddess Artemis, and as such she was worshipped in Myra of Lycia. The Roman equivalent of the goddess Eleutheria is Libertas, a goddess in her own right, and a personification of liberty. Etymology For R. F. Willets, Cretan dialect 'Eleuthia' would connect Eileithyia (or perhaps the goddess "Eleutheria") to Eleusis. The name is probably related with a city in Crete named Eleutherna. Walter Burkert believes that Eileithyia is the Greek goddess of birth and that her name is pure-Greek. However the relation with the Greek prefix ' is uncertain, because the prefix appears in some Pre-Greek toponyms like ' (Eleutherna). Hyginus describes Eleutheria as a daughter of Zeus and He ...
