Johann Friedrich Wilhelm Herbst
Johann Friedrich Wilhelm Herbst (1 November 1743 – 5 November 1807) was a German naturalist and entomologist from Petershagen, Minden-Ravensberg. He served as a chaplain in the Prussian army. His marriage in Berlin, 1770, with Euphrosyne Luise Sophie (1742–1805), daughter of the Prussian ''Hofrat'' Libert Waldschmidt seems to have been childless. He was the joint editor, with Carl Gustav Jablonsky Carl Gustav Jablonsky (1756 – 25 May 1787) was a Berlin naturalist, entomologist and illustrator. He was also the private secretary to the Queen of Prussia, Elisabeth Christine of Brunswick-Wolfenbüttel-Bevern. He died at the age of 31. He w ...

Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line ( intert ...

Calappa (crab)
''Calappa'' is a genus of crabs known commonly as box crabs or shame-faced crabs. The name ''box crab'' comes from their distinctly bulky carapace, and the name ''shame-faced'' is from anthropomorphism, anthropomorphising the way the crab's chela (organ), chelae (claws) fold up and cover its face, as if it were hiding its face in shame. Species There are 43 extant species in the genus: *''Calappa acutispina'' Lai, Chan & Ng, 2006 *''Calappa africana'' Lai & Ng, 2006 *''Calappa bicornis'' Miers, 1884 *''Calappa bilineata'' Ng, Lai & Aungtonya, 2002 *''Calappa calappa'' (Linnaeus, 1758) *''Calappa capellonis'' Laurie, 1906 *''Calappa cinerea'' Holthuis, 1958 *''Calappa clypeata'' Borradaile, 1903 *''Calappa conifera'' Galil, 1997 *''Calappa convexa'' Saussure, 1853 *''Calappa dumortieri'' Guinot, 1962 *''Calappa exanthematosa'' Alcock & Anderson, 1894 *''Calappa flammea'' (Herbst, 1794) *''Calappa galloides'' Stimpson, 1859 *''Calappa gallus'' (Herbst, 1803) *''Calappa granulata'' ...

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 opin ...

Crustaceans Of The Atlantic Ocean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

Taxa Named By Johann Friedrich Wilhelm Herbst
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
