The Mediterranean sea is a predominantly warm body of water, thus ''O. phosphorica'' is a warm-water Jellyfish. Global warming has facilitated the proliferation of the species throughout the Mediterranean sea. References Olindiidae Animals described in 1841 {{hydrozoa-stub ...

Hydrozoan
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] |
Olindiidae
Olindiidae is a family of hydrozoans in the order Limnomedusae. They have a polyp (zoology), polyp phase and a Jellyfish, medusa phase. The polyps are generally small (1 mm) and solitary, but a few species are colonial. They have a varying number of tentacles and can reproduce by budding. In the largest species, the medusae can grow to . Centripetal canals may be present or absent and the radial canals are unbranched. The gonads are beside the radial canals, except in ''Limnocnida'', where they are on the manubrium. The fertilised eggs develop into planula larvae which become polyps. These multiply Asexual reproduction, asexually or can bud off medusae. In some species, medusae are only produced when the water temperature exceeds a certain level. Most species are marine, but several can also be found in brackish water and a few, notably ''Craspedacusta'' (such as ''Craspedacusta sowerbii, C. sowerbii'') and ''Limnocnida'', are found in fresh water.Didžiulis, Viktoras: Craspe ...
