Carparachne
''Carparachne'' is a genus of Namibian huntsman spiders that was first described by R. F. Lawrence in 1962. it contains two species, found in Namibia: '' C. alba'' and '' C. aureoflava''. The golden wheel spider (''C. aureoflava'') uses cartwheeling to move across hot, sandy ground, similar to the related ''Cebrennus rechenbergi'', which uses a flic-flac motion.

Wheel Spider
The wheel spider or golden wheel spider (''Carparachne aureoflava''), is a huntsman spider native to the Namib Desert of Southern Africa. This spider should not be confused with ''Leucorchestris arenicola'', a spider sharing the same common name as well as the same locale. The spider escapes parasitic Spider wasp, pompilid wasps by flipping onto its side and rotating locomotion in living systems, cartwheeling down sand dunes at speeds of up to 44 turns per second. Characteristics Wheel spiders are up to 20 mm in size, with males and females the same size. The wheel spider is a nocturnal, free-ranging hunter, coming out at night to prey on insects and other small invertebrates. Its bite is mildly venomous, but the spider is not known to be harmful to humans. The wheel spider does not produce a web. Its principal line of defence against predation is to bury itself in a silk-lined burrow extending 40–50 cm deep. During the process of digging its burrow, the spider can s ...

The spider escapes parasitic pompilid wasps by flipping onto its side and cartwheeling down sand dune A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex.

Sparassidae
Huntsman spiders, members of the family Sparassidae (formerly Heteropodidae), are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places (forests, mine shafts, woodpiles, wooden shacks). In southern Africa the genus ''Palystes'' are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related. More than a thousand Sparassidae species occur in most warm temperate to tropical regions of the world, including much of Australasia, Africa, Asia, the Mediterranean Basin, and the Americas. Several species of huntsman spider can use an unusual form of locomotion. The wheel spider (''Carparachne aureoflava'') from the Namib uses a cartwheeling motion which gives it its name, while ''Cebrennus rechenbergi ...

Cebrennus Rechenbergi
''Cebrennus rechenbergi'', also known as the Moroccan flic-flac spider and cartwheeling spider, is a species of huntsman spider indigenous to the sand dunes of the Erg Chebbi desert in Morocco. If provoked or threatened it can escape by doubling its normal walking speed using forward or backward flips similar to acrobatic flic-flac movements used by gymnasts. ''C. rechenbergi'' is the only spider known to use this unique form of rolling locomotion. The discovery of the Moroccan flic-flac spider has influenced biomimetic robot research, resulting in the development of an experimental robot based on the spider's motion.King, R.S. (2013). ''BiLBIQ: A Biologically Inspired Robot with Walking and Rolling Locomotion''. Biosystems and Biorobotics. 2. Springer, Verlag, Berlin, Heidelberg. Etymology The spider is named after its discoverer, Ingo Rechenberg, bionics professor at the Technische Universität Berlin. Rechenberg may have first encountered the spider on a trip to Mor ...

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Flic-flac
Because ballet became formalized in France, a significant part of ballet terminology is in the French language. A À la seconde () (Literally "to second") If a step is done "à la seconde," it is done to the side. 'Second position'. It can also be a balance extending one foot off the ground in ‘Second Position’. À la quatrième () One of the directions of body, facing the audience (''en face''), arms in second position, with one leg extended either to fourth position in front (''quatrième devant'') or fourth position behind (''quatrième derrière''). À terre () Touching the floor; on the floor. Adagio Italian, or French ''adage'', meaning 'slowly, at ease.' # Slow movements performed with fluidity and grace. # One of the typical exercises of a traditional ballet class, done both at barre and in center, featuring slow, controlled movements. # The section of a '' grand pas'' (e.g., '' grand pas de deux''), often referred to as ''grand adage'', that features dance part ...

Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...

Endemic Fauna Of Namibia
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 (ecology), 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, Cytisus aeolicus'' is an endemite of the Italian flora. ''Enidae, Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a Invasive species, 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 specie ...
