Charles Spence Bate
Charles Spence Bate, FRS (March 16, 1819 – July 29, 1889) was a British zoologist and dentist. Life He was born at Trenick House near Truro, the son of Charles Bate (1789–1872) and Harriet Spence (1788–1879). Charles adopted "Spence Bate" as his surname, perhaps to distinguish himself from his father, and used that name consistently in his publications; it was also used consistently by his contemporaries to refer to him. He practiced dentistry first at Swansea, and then at Plymouth, taking over his father's practice. He was president of the Odontology Society. He was an authority on the Crustacea, for which he was elected a fellow of the Royal Society in 1861, and a frequent correspondent of Charles Darwin, mostly concerning their shared interest in barnacles. Together with John Obadiah Westwood, he wrote "''A history of the British sessile-eyed Crustacea''" in 1868. He wrote reports on the crustaceans collected during the HMS ''Challenger'' expedition of 1872–1876. ... [...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] |
Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe (2009 ...

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 ...

Umgeni River
The Umgeni River or Mgeni River ( zu, uMngeni) is a river in KwaZulu-Natal, South Africa. It rises in the "Dargle" in the KZN Midlands, and its mouth is at Durban, some distance north of Durban's natural harbour. The name is taken to mean "the river of entrance" in Zulu, though other meanings have been proposed. The river is approximately long with a catchment area of . The Howick Falls are some famous waterfalls on the Mngeni. Tributaries A noteworthy tributary is the Msunduzi River, which joins it between Nagle and Inanda dams. Higher up its course, the Msunduzi (or 'Dusi' for short) passes through the KwaZulu-Natal capital Pietermaritzburg. A famous downriver race, the Dusi Canoe Marathon takes place between the capital and Durban, attracting thousands of canoeists for the three-day event held in January every year. A small tributary that has an impact exceeding its size and length is the Lions River which joins the Umgeni about 4 kilometers upstream of Midmar Dam (near Li ...

Mtamvuna River
Mtamvuna River is a river that forms the border between KwaZulu-Natal and the Eastern Cape Provinces in South Africa. The river has a wide mouth and flows into the Indian Ocean just south of Port Edward. The Mtamvuna river is approximately 162 km long with a catchment area of 1,553 km². The name means "the reaper of mouthfuls" because of the damage the river does to crops during floods. History Historically the Mtamvuna River is the northern limit of the Pondoland region. In 1552 a Portuguese ship ran aground at the mouth of the Mtamvuna River and a group of local people got close to the sailors wishing to trade with them. Ecology The Umtamvuna Nature Reserve is a protected area located close to the deep Mtamvuna River Gorge. Presently this river is part of the Mvoti to Umzimkulu Water Management Area.

Crustaceans Described In 1888
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, Myriapoda, myriapods and Chelicerata, chelicerates, by the possession of biramous (two-parte ...

Taxa Named By Charles Spence Bate
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
