Lobularia (coral)
''Lobularia'' is a genus of soft corals in the family Alcyoniidae. Former species According to the World Register of Marine Species, none of the species previously classified in this genus are accepted as members. So while the genus exists, it is unoccupied. Previously classified species and their new accepted classifications are as follows: *''Lobularia digitata'' (Linnaeus, 1758) accepted as ''Alcyonium digitatum'' Linnaeus, 1758 *''Lobularia pauciflora'' (Ehrenberg, 1834) accepted as ''Cladiella pauciflora'' Ehrenberg, 1834 *''Lobularia rubiformis'' Eherenberg, 1834 accepted as ''Gersemia rubiformis ''Gersemia rubiformis'', commonly known as the sea strawberry, is a species of soft coral in the family Nephtheidae. It is found in the northwest Atlantic and the northeast Pacific Oceans. Description ''Gersemia rubiformis'' is a colonial cora ...''

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Alcyonacea
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in c ...

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 ...

Alcyoniidae
Alcyoniidae is a family of leathery or soft corals in the phylum Cnidaria.Leathery corals Wildsingapore.com (2010-02-28). Retrieved on 2013-09-17. Description A colony of leathery coral is stiff, hard and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. Members of the family may have two kinds of polyps; the autozooids have long trunks and eight tiny branched tentacles and project from the shared leathery tissue while the siphonozooids remain below the surface and pump water for the colony. They appear as tiny hollows or mounds among the taller autozooids. Different genera have different proportions of these two kinds of polyps. The autozooids only emerge when the colony is fully submerged.Distribution and habitat Leathe ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcyonium Digitatum
''Alcyonium digitatum'' or dead man's fingers is a species of soft coral in the family Alcyoniidae. It is found around the coasts of the northern Atlantic Ocean and other temperate waters such as the South Pacific. Description Dead man's fingers is a colonial coral forming clumps of yellow, white or cream-coloured fleshy masses of finger-like lobes. The surface layer include many sclerites which form a crust. The individual polyps are white and translucent, and project from the leathery surface when feeding, giving the colony a furry appearance. Distribution and habitat Dead man's fingers is found along the Atlantic coasts of north west Europe from Portugal to Norway, most recently being discovered in the unchartered waters of Jammerbugt bay off the north-west coast of Denmark by a 2020 seafloor mapping project led by explorer Klaus Thymann. The species also occurs in parts of Canada, northeastern coast of the United States, the Gulf of Maine and the Bay of Fundy and the norther ...

Cladiella Pauciflora
''Cladiella'' is a genus of soft corals native to the Indo-Pacific region. These corals are commonly known as colt corals or finger leather corals and are often kept in reef aquaria. They grow fast, have short rounded or conical lobes and are sticky to the touch owing to the production of much mucus. They are creamy or pale grey in colour. The polyps are fully retractable and give the colony a fluffy look when extended. They may be a contrasting green or brown hue. Species The World Register of Marine Species lists the following species: *'' Cladiella arborea'' (Utinomi, 1954) *'' Cladiella arbusculoides'' Verseveldt & Benayahu, 1978 *'' Cladiella aspera'' Tixier-Durivault, 1970 *'' Cladiella australis'' (Macfadyen, 1936) *'' Cladiella bottai'' (Tixier-Durivault, 1943) *'' Cladiella brachyclados'' Ehrenberg, 1834 *'' Cladiella ceylonica'' (Pratt, 1905) *'' Cladiella conifera'' (Tixier-Durivault, 1943) *'' Cladiella crassa'' (Tixier-Durivault, 1943) *'' Cladiella daphnae'' van ...

Gersemia Rubiformis
''Gersemia rubiformis'', commonly known as the sea strawberry, is a species of soft coral in the family Nephtheidae. It is found in the northwest Atlantic and the northeast Pacific Oceans. Description ''Gersemia rubiformis'' is a colonial coral that grows in the form of knobbly clumps. The colonies are erect and branch from one main stalk. The polyps are concentrated near the ends of the narrower terminal branches and are non-retractile in their calyces. The branches are not rigid but are stiffened by the presence of sclerites, and can sway gently in the current. The sclerites are red, some being irregular and shaped like miniature capstans. ''Gersemia rubiformis'' does not contain the symbiotic alga zooxanthella. Distribution ''Gersemia rubiformis'' is found in polar to temperate regions of the Arctic Ocean and the north west Atlantic Ocean from the coasts of Canada south to Cape Hatteras in North Carolina. A separate population is found in the Pacific Ocean off the coasts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
