Kirchenpaueriidae
Kirchenpaueriidae is a family of hydrozoans in the superfamily Plumularioidea. Their hydrocladia are characteristically set in an alternating fashion as one progresses along the stems, forming two neat rows except in '' Oswaldella laertesi'', which has three such rows. The alternating placement of the hydrocladia can be used to distinguish them from the Plumulariidae Plumulariidae is a family (biology), family of hydrozoans. Genus According to the World Register of Marine Species, the following genus, genera belong to this family: *''Callicarpa (hydrozoan), Callicarpa'' Fewkes, 1881 *''Cladacanthella'' Calde ... which may look superficially similar.

Plumularioidea
Plumularioidea is a superfamily of hydrozoans in the order Leptothecata. This superfamily unites about 45 genera in the following families: * Aglaopheniidae Marktanner-Turneretscher, 1890 * Halopterididae Millard, 1962 * Kirchenpaueriidae Stechow, 1921 * Phylactothecidae Stechow, 1921 * Plumaleciidae Choong & Calder, 2018 * Plumulariidae McCrady, 1859 * Schizotrichidae Peña Cantero, Sentandreu & Latorre, 2010 These thecate hydroids grow in erect colonies, branched in some species but unbranched in others. Each branch may bear a single or several animals. In the latter case the hydrothecae are arranged in a neat single file; in either case they are not set on stalks but grow from the branches directly. The hydrothecase have a cusped or even rim and instead of a diaphragm a well-defined floor with a hydropore that is usually off-center. The hydranths have a conical hypostome and a single whorl of thread-like tentacles. The gastrodermis contains areas with and others ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

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] |
Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.
