Tartarus Mullamullangensis
''Tartarus mullamullangensis'', informally known as the Mullamullang cave spider, is a palm-sized, long-legged cave spider from Western Australia. Completely adapted to cave living, it is blind and totally lacks pigmentation, giving it a creamy white appearance. The cylindrical lampshade-shaped web is spun out between rocks. The species is closely related to spiders found in forests of Southern Australia. This makes it likely that ''T. mullamullangensis'' is a relict species from the time when the now arid region was much more humid. First photo of the N37 cave spider discovered and photographed by Bill Crowle under the cairn built at the end of N37, (Mullamullang). Two miles underground along a large passage of many rockpiles, sanddunes and lakes, and about 300 ft under the surface. The black & white image Bill Crowle made can be seen on the right. The spider was later described by Mike Gray, who was on this trip. Name The species name is derived from Mullamullang, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Relict (biology)
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group di ...

Arid Region
A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic. Most arid climates straddle the Equator; these regions include parts of Africa, Asia, South America, North America, and Australia. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity.

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as '' speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgan ...

Nullarbor Plain
The Nullarbor Plain ( ; Latin: feminine of , 'no', and , 'tree') is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coast with the Great Victoria Desert to its north. It is the world's largest single exposure of limestone bedrock, and occupies an area of about . At its widest point, it stretches about from east to west across the border between South Australia and Western Australia. History Historically, the Nullarbor was seasonally occupied by Indigenous Australian people, the Mirning clans and Yinyila people. Traditionally, the area was called ''Oondiri'', which is said to mean "the waterless". The first Europeans known to have sighted and mapped the Nullarbor coast were Captain François Thijssen and Councillor of the Indies, Pieter Nuyts, on the Dutch East Indiaman '' 't Gulden Zeepaert'' (the Golden Seahorse). In 1626–1627, they charted a stretch of the southern Australian coas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stiphidiidae
Stiphidiidae, also called sheetweb spiders, is a family of araneomorph spiders first described in 1917. Most species are medium size (''Stiphidion facetum'' is about long) and speckled brown with long legs. All members of this family occur in New Zealand and Australia except for '' Asmea''. They build a horizontal sheet-like web under rocks, hence the name "sheetweb spiders". The largest of New Zealand's species is ''Cambridgea foliata'', with a body length up to and a span of up to . Hikers and trampers often find their sheet-like webs that can be up to across, but the spider itself is nocturnal, spending the day time inside its web tunnel. It can also be found in gardens and males may enter human homes. Their large size, including mouth parts up to long, may be intimidating, but it is considered harmless to humans and bites are extremely rare. Genera , the World Spider Catalog accepts the following genera: *'' Aorangia'' Forster & Wilton, 1973 — New Zealand *'' Asm ...

Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
