Pycnotheca Mirabilis
''Pycnotheca mirabilis'', The feathery hydroid, is a colonial hydroid in the family Kirchenpaueriidae. Feathery hydroids are often white and grow in crowded colonies resembling upright feathers. The stems may grow to 3 cm in total height. The reproductive bodies are found at the base of the stems and resemble beehives. Millard, N.A.H. 1975. Monograph on the Hydroida of Southern Africa.

Protologue
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 polyp (zoology), polypoid and a medusa (biology), 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 tetraphylla, Lir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 opini ...

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. There are six genera recognized in the family Kirchenpaueriidae: * '' Halicornopsis'' * '' Kirchenpaueria'' * '' Ophinella'' * '' Oswaldella'' * '' Pycnotheca'' * '' Wimveria'' References * MarineSpecies.org (2008)Kirchenpaueriidae Retrieved 2008-JUL-08. * Schuchert, Peter (2008) Retrieved 2008-JUL-08.

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vema Seamount
Vema Seamount is a seamount in the South Atlantic Ocean. Discovered in 1959 by a ship with the same name, it lies from Tristan da Cunha and northwest of Cape Town. The seamount has a flat top at a mean depth of which was eroded into the seamount at a time when sea levels were lower; the shallowest point lies at depth. The seamount was formed between 15-11 million years ago, possibly by a hotspot. The seamount rises high enough that its summit is at shallow depth, allowing sunlight to reach it and thus permitting the growth of kelp and algae. A number of sea animals and fish are encountered on the seamount; active fisheries existed at Vema Seamount and caused the disappearance of some animal species. History Vema Seamount was discovered by the research ship RV Vema of the Lamont–Doherty Earth Observatory in 1959. Vema is one of the first seamounts to be the subject of scientific study, and the first seamount investigated by scuba divers without special equipment. Vema li ...

Fauna Of South Africa
The fauna of South Africa is diverse and largely typical of the ecosystems in Africa. South Africa is ranked sixth out of the world's 17 megadiverse countries. Many endemic species are unique to South Africa. The country is among the world leaders in conservation, but at the time wildlife is threatened by poaching and canned hunting. Habitats The topography and geology of South Africa is extremely varied, resulting in a wide variety of habitats. Due to this, South Africa enjoys high biodiversity, and is ranked sixth out of the world's seventeen megadiverse countries. In the extreme northwest of the country is true desert, which is the southernmost end of the Namib desert, a desert that is at least 55 million years old, making it the oldest desert in the world. This arid corner intergrades into the extensive semi-arid Karoo found across much of South Africa, covering the Northern Cape and into parts of the Western Cape, Eastern Cape and the Free State. This biome used to be extens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
