Hadogenes Bicolor
''Hadogenes bicolor'' is a species of scorpion endemic to South Africa. This species is often confused with ''H. troglodytes.'' Description The legs, tail and chelicerae of ''H. bicolor'' are paler than the carapace, forming a marked color contrast. The overall appearance is consistent with that of the other members of Hadogenes, the body construction is flattened which allows them to navigate safely in and out the cracks and crevices that comprise their habitats. Distribution and ecology ''Hadogenes bicolor'' is endemic to Mpumalanga and Limpopo provinces, South Africa. It lives only in rocky outcrops along the Drakensberg escarpment at altitudes of . It lives in crevices in dolerite and granite rocks in areas with an annual rainfall of . Taxonomy ''Hadogenes bicolor'' was first described by W. F. Purcell in 1899, based on material collected by the Reverend J. W. Daneel "about twenty miles east of Pietersburg Transvaal Transvaal is a historical geographic term associated wi ...

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] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Arthropods Of South Africa
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hadogenes Troglodytes
''Hadogenes troglodytes'' is a species of scorpion from southern Africa. It is commonly known as the flat rock scorpion and commonly sold on the exotic pet market. It was once regarded as having the longest recorded body length of any scorpion, reaching up to 20 cm; however ''Heterometrus swammerdami'' currently holds the record for being the world's largest scorpion at 9 inches (23 cm) in length. May be confused with Hadogenes bicolor. Distribution It is known from the Limpopo province, reaching the northern parts of the Mpumalanga provinces. It occurs up into Botswana, Zimbabwe, and western Mozambique. Description The overall body appearance is consistent with other members of Hadogenes. The carapace, pedipalps, chela, sternites, and metasoma are all flattened allowing them to maneuver in and out of the small cracks and crevices that are abundant in the rocky outcrops they are endemic to. Characterized by highly specialized curved telotarsal claws which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hadogenes Newlandsi
''Hadogenes'' is a genus of African scorpions (including the world's longest, ''Hadogenes troglodytes''). This genus is distinguished by its members which have an unusually flat overall appearance that allows them to quickly get in and out of the cracks and cervices that are generally abundant in their rocky habitats. Occurring in South Africa, Namibia, Botswana, Zimbabwe and Mozambique. Members of the genus also have special claws on their tarsus which allows them specialized maneuverability in their environments. The members of this genus have demonstrated an inability to travel across the sand and will perish in the heat when unable to find shelter for extended periods of time. The members of this genus are threatened by habitat loss due to mining as well and by poaching for the exotic pet trade. Members * '' Hadogenes bicolor'' Purcell, 1899 * '' Hadogenes gracilis'' Hewitt, 1909 * ''Hadogenes granulatus'' Purcell, 1901 * '' Hadogenes gunningi'' Purcell, 1899 * ''Hadogene ...

Transvaal Province
The Province of the Transvaal ( af, Provinsie van Transvaal), commonly referred to as the Transvaal (; ), was a province of South Africa from 1910 until 1994, when a new constitution subdivided it following the end of apartheid. The name "Transvaal" refers to the province's geographical location to the north of the Vaal River. Its capital was Pretoria, which was also the country's executive capital. History In 1910, four British colonies united to form the Union of South Africa. The Transvaal Colony, which had been formed out of the bulk of the old South African Republic after the Second Boer War, became the Transvaal Province in the new union. Half a century later, in 1961, the union ceased to be part of the Commonwealth of Nations and became the Republic of South Africa. The PWV (Pretoria-Witwatersrand-Vereeniging) conurbation in the Transvaal, centred on Pretoria and Johannesburg, became South Africa's economic powerhouse, a position it still holds today as Gauteng Province ...

Zoutpansberg
Zoutpansberg was the north-eastern division of the Transvaal, South Africa, encompassing an area of 25,654 square miles. The chief towns at the time were Pietersburg and Leydsdorp. It was divided into two districts (west and east) prior to the first general election of the Union of South Africa in 1910. Since 2005 the area is divided into the Capricorn, Vhembe and Mopani district municipalities of Limpopo province. Voortrekkers This was the district to which Louis Tregardt and Hans van Rensburg, the forerunners of the Great Trek, journeyed in 1835. In 1845 Hendrik Potgieter, a prominent leader of the Voortrekkers, moved there. The Zoutpansberg Boers formed a semi-independent community, and in 1857 Stephanus Schoeman, their commandant-general, sided against Marthinus Pretorius and Paul Kruger when they invaded the Orange Free State. South African Republic It was not until 1864 that Zoutpansberg was definitively incorporated in the South African Republic as a result of the Tra ...

Alpha Taxonomy
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms.
