Sydney Funnel-web Spider
The Sydney funnel-web spider (''Atrax robustus'') is a species of venomous Mygalomorphae, mygalomorph spider native to eastern Australia, usually found within a radius of Sydney. It is a member of a group of spiders known as Australian funnel-web spiders. Its bite is capable of causing serious illness or death in humans if left untreated. The Sydney funnel-web has a body length ranging from . Both sexes are glossy and darkly coloured, ranging from blue-black, to black, to shades of brown or dark-plum coloured. Taxonomy Octavius Pickard-Cambridge was the first to describe the Sydney funnel-web spider, from a female specimen housed in the British Museum in 1877. Establishing the genus ''Atrax'', he named it ''Atrax robustus''. The species name is derived from the Latin ''robustus'', "strong/sturdy/mature". Some years later, William Joseph Rainbow described a male Sydney funnel-web as a new species—''Euctimena tibialis''—from a spider he found under a log in Turramurra, an ...

Octavius Pickard-Cambridge
Octavius Pickard-Cambridge Fellow of the Royal Society, FRS (3 November 1828 – 9 March 1917) was an England, English clergyman and zoologist. He was a keen arachnologist who described and named more than 900 species of spider. Life and work Pickard-Cambridge was born in Bloxworth rectory, Dorset, the fifth son of Rev. George Pickard, rector and squire of Bloxworth: the family changed its name to Pickard-Cambridge in 1848 after receiving the property left behind by a relative, Charles Owen Cambridge, of Whitminster House in Gloucestershire. Octavius was tutored at home by the poet William Barnes, after failing to receive admission to Winchester College. He also learned to play the violin from Sidney Smith. He then studied law in London before theology at the Durham University, University of Durham. He was very active and made many friends in this period. He served as steward at steeplechases and presided over the college choral society. In 1857 he presented the Pickard-Camb ...

Anthony Musgrave (entomologist)
Anthony Musgrave (9 July 18954 June 1959) was an Australian entomologist. Born in Queensland, Australia, he is known for penning ''Bibliography of Australian Entomology'' (1932). He was the great-nephew of Anthony Musgrave who was Secretary of State for the Colonies. Early life Anthony Musgrave was born 9 July 1895 in Cooktown, Queensland, Australia. His father was Anthony Musgrave, a civil servant, and his mother was Elizabeth Anne (née Colles). He studied at the Hayfield Preparatory School in Homebush and the Sydney Church of England Grammar School. Career As an entomologist, Musgrave is known for his 1932 work, ''Bibliography of Australian Entomology''. He worked at the Australian Museum, initially as a librarian for a year, before climbing up the ranks to become Assistant Entomologist, and eventually the museum's entomologist, a title later changed to "Curator of Insects and Arachnids". He displayed much knowledge on insects and arachnids; his area of expertise were ticks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta Atracotoxin
Delta atracotoxin (δ-ACTX-Ar1, robustoxin, or robustotoxin) is a low-molecular-weight neurotoxic polypeptide found in the venom of the Sydney funnel-web spider (''Atrax robustus''). Delta atracotoxin produces potentially fatal neurotoxic symptoms in primates, by slowing the inactivation of sodium ion channels in autonomic and motor neurons. In the spiders' intended insect prey, the toxin exerts this same activity upon potassium and calcium ion channels. The structure of atracotoxin comprises a core beta region with a cystine knot motif, a feature seen in other neurotoxic polypeptides. History Since 1927, records are kept of envenomations of humans by the Sydney funnel-web spider, and 14 deaths have been reported in medical literature between 1927 and 1981, when the antivenom became available. In all cases in which the sex of the spider was determined, death occurred after a bite from a male spider. Structure Delta atracotoxin is a 42-residue peptide toxin with the ch ...

Intravenous Therapy
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab-eating Macaque
The crab-eating macaque (''Macaca fascicularis''), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans. The species has been alternately seen as an agricultural pest, a sacred animal, and, more recently, the subject of medical experiments. The crab-eating macaque lives in matrilineal social groups of up to eight individuals dominated by females. Male members leave the group when they reach puberty. It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflicts ...

Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids. At present, the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microhabitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spinneret (spider)
A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. While most spiders have six spinnerets, some have two, four, or eight. They can move both independently and in concert. Most spinnerets are not simple structures with a single orifice producing a single thread, but complex structures of many microscopic spigots, each producing one filament. This produces the necessary orientation of the protein molecules, without which the silk would be weak and useless. Spigots can be singular or found in groups, which also permits spiders to combine multiple filaments in different ways to produce many kinds of silk for various purposes. Spinneret morphology can help arachnologists identify the taxon of a specimen and the specific morphology of a spigot can determine its use as well ...

Cephalothorax
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind. (The terms ''prosoma'' and ''opisthosoma'' are equivalent to ''cephalothorax'' and ''abdomen'' in some groups.) The word ''cephalothorax'' is derived from the Greek words for head (, ') and thorax (, '). This fusion of the head and thorax is seen in chelicerates and crustaceans; in other groups, such as the Hexapoda (including insects), the head remains free of the thorax. In horseshoe crabs and many crustaceans, a hard shell called the carapace covers the cephalothorax.

Hadronyche Formidabilis
''Hadronyche formidabilis'', the northern tree-dwelling funnel-web spider, is a medically significant mygalomorph spider found in Queensland and New South Wales. It is also known as the Northern Rivers funnel-web spider or northern funnel-web spider. Taxonomy A member of the genus '' Hadronyche'', the northern tree-dwelling funnel-web spider was first described in 1914, by William Joseph Rainbow in the genus ''Atrax'', having been collected from the vicinity of the Richmond River. Rainbow suspected it may have needed to be placed in a genus separate to ''Atrax'' at the time, but demurred due to the lack of male specimens. The species name is derived from the Latin ''formidabilis'' "terrifying". Within the genus ''Hadronyche'', it is classified in the heterogeneous ''cerberea'' group, alongside the southern tree-dwelling funnel-web ('' H. cerberea''), the Blue Mountains funnel-web ('' H. versuta'') and 12 other species from southern New South Wales and Victoria.
