Max Carl Wilhelm Weber
Max Carl Wilhelm Weber van Bosse or Max Wilhelm Carl Weber (5 December 1852, in Bonn – 7 February 1937, in Eerbeek) was a German-Dutch zoologist and biogeographer. Weber studied at the University of Bonn, then at the Humboldt University in Berlin with the zoologist Eduard Carl von Martens (1831–1904). He obtained his doctorate in 1877. Weber taught at the University of Utrecht then participated in an expedition to the Barents Sea. He became Professor of Zoology, Anatomy and Physiology at the University of Amsterdam in 1883. In the same year he received naturalised Dutch citizenship. His discoveries as leader of the Siboga Expedition led him to propose Weber's line, which encloses the region in which the mammalian fauna is exclusively Australasian, as an alternative to Wallace's Line. As is the case with plant species, faunal surveys revealed that for most vertebrate groups Wallace’s line was not the most significant biogeographic boundary. The Tanimbar Island group, and ...

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] |
Goby
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of ''Fishes of the World'' this suborder is elevated to an order Gobiiformes within the clade Percomorpha. Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny ''Pholidichthys leucotaenia''. The word goby derives from the Latin ''gobius'' meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxyurichthys
''Oxyurichthys'' is a genus of fish in the subfamily Gobionellinae, commonly known as arrowfin gobies. They are distributed in the tropical and subtropical Indian and Pacific Oceans; one species is also known from the western Atlantic Ocean. Most species live in shallow waters under 10 meters deep over fine substrates such as silt. Species The following species are recognized in the genus ''Oxyurichthys'': * '' Oxyurichthys auchenolepis'' Bleeker, 1876 (scaly-nape tentacle goby) * '' Oxyurichthys chinensis'' Pezold & Larson, 2015 * '' Oxyurichthys cornutus'' McCulloch & Waite, 1918 (horned tentacle goby) * ''Oxyurichthys guibei'' J.L.B. Smith, 1959 * '' Oxyurichthys heisei'' Pezold, 1998 * '' Oxyurichthys keiensis'' (J.L.B. Smith, 1938) (Kei goby) * '' Oxyurichthys lemayi'' (J.L.B. Smith, 1947) (lace goby) * '' Oxyurichthys limophilus'' Pezold & Larson, 2015 * '' Oxyurichthys lonchotus'' ( O. P. Jenkins, 1903) (speartail mudgoby) * '' Oxyurichthys microlepis'' (Bleeker, 18 ...

Fish Of The Pacific Ocean
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Taxa Named By Max Carl Wilhelm Weber
In biology, a taxon (back-formation from ''Taxonomy (biology), 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 Taxonomic rank, 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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu.
