Corymorphidae
Corymorphidae is a family of hydroid cnidarians. For long placed in a presumed superfamily or infraorder Tubulariida of suborder Capitata, they are actually close relatives of the Hydridae and are now united with these and a number of relatives in a newly recognized suborder Aplanulata.Schuchert, P. (2013)Corymorphidae Allman, 1872.In: Schuchert, P. (2018). World Hydrozoa Database. Accessed through: World Register of Marine Species on 2018-02-03. Most, if not all species in this family grow on stalks and resemble small flowers. According to the World Register of Marine Species, the following genera are contained in this family: *'' Branchiocerianthus'' Mark, 1898 *''Corymorpha'' M.

Aplanulata
Aplanulata is a suborder of Hydrozoa, a class of marine and freshwater invertebrates belonging to the phylum Cnidaria. The group have lost its planula larval stage, and the only remnants of the medusa stage is when they functions as gonophores attached to the polyp. Families According to the World Register of Marine Species, the following families are found in this suborder : * Acaulidae Fraser, 1924 * Boeromedusidae Bouillon, 1995 * Boreohydridae Westblad, 1947 * Candelabridae Stechow, 1921 *Corymorphidae Allman, 1872 * Hydridae Dana, 1846 * Margelopsidae Uchida, 1927 * Paracorynidae Picard, 1957 * Protohydridae Allman, 1888 *Tubulariidae Tubulariidae is a family of hydroid cnidarians.

Capitata (Hydrozoa)
Capitata is a suborder of Hydrozoa, a class of marine invertebrates belonging to the phylum Cnidaria. Characteristics Members of this suborder are characterised by the tentacles of the polyps terminating in knobs. In some species these are only present in juvenile forms being replaced in adults by more threadlike tentacles. A high nematocyst concentration is present in the knobs. A few species in this group are better known as their solitary medusa form than as their polyp form. These include ''Sarsia'', ''Polyorchis'' and '' Cladonema''. Families According to the World Register of Marine Species, the following families are found in this suborder : * Asyncorynidae Kramp, 1949 * Cladocorynidae Allman, 1872 *Cladonematidae Gegenbaur, 1857 * Corynidae Johnston, 1836 * Halimedusidae Arai & Brinckmann-Voss, 1980 * Hydrocorynidae Rees, 1957 *Milleporidae Fleming, 1828 * Moerisiidae Poche, 1914 *Pennariidae McCrady, 1859 * Porpitidae Goldfuss, 1818 * Pseudosolanderiidae Bouillon & G ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Cnidarians
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and ...

Hydrozoa
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 hydro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
