Deinopidae
Deinopidae, also known as net casting spiders, is a family of cribellate spiders first described by Carl Ludwig Koch in 1850. It consists of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed size, entangling any prey that touch them. The posterior median eyes have excellent night vision, allowing them to cast nets accurately in low-light conditions. These eyes are larger than the others, and sometimes makes these spiders appear to only have two eyes. Ogre-faced spiders (''Deinopis'') are the best known genus in this family. The name refers to the perceived physical similarity to the mythological creature of the same name. This family also includes the humped-back spiders (''Menneus''). They are distributed through tropics worldwide from Australia to Africa and the Americas. In Florida, ''Deinopis'' often hangs upside down from a silk line un ...

Menneus
''Menneus'' is a genus of net-casting spiders that was first described by Eugène Simon in 1876. It includes the former genera ''Avella'' and ''Avellopsis''. Species are found in Australia, New Caledonia, and eastern and southern Africa. Originally placed with the cribellate orb-weavers, it was moved to the Deinopidae in 1967. Species it contains fourteen species: *'' Menneus aussie'' Coddington, Kuntner & Opell, 2012 – Australia (Queensland, New South Wales), New Caledonia *'' Menneus bituberculatus'' Coddington, Kuntner & Opell, 2012 – Australia (Queensland), possibly New Guinea *'' Menneus camelus'' Pocock, 1902 – South Africa *'' Menneus capensis'' (Purcell Henry Purcell (, rare: September 1659 – 21 November 1695) was an English composer.

Deinopis
''Deinopis'', also known as net-casting spiders, gladiator spiders and ogre-faced spiders, is a genus of net-casting spiders that was first described by W. S. MacLeay in 1839. Its distribution is widely tropical and subtropical. They catch their prey using a specially spun "net". The name is derived from the Greek (''deinos''), meaning "fearful", and ''opis'', meaning "appearance", referring to their ogre-like faces. The spelling "''Dinopis''" is also found, but is regarded as an "unjustified emendation". Net-casting Spiders in the genus ''Deinopis'' catch their prey in an unusual fashion. They first spin a small upright rectangular cribellate web. This is then detached from its supporting threads and held horizontally above the ground by the spider's long front two pairs of legs while the spider hangs almost vertically. Passing prey is then captured by dropping the "net" over it. Eyes The two posterior median eyes are enlarged and forward-facing. These eyes have a wide field ...

Cribellate
Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates. In certain groups of diatoms it refers to microscopically punctured regions of the frustule, or outer layer. In certain groups of spider species, so-called cribellate spiders, the cribellum is a silk spinning organ. Unlike the usual spinnerets of spiders, the cribellum consists of one or more plates covered in thousands of tiny spigots, tiny holes that hardly project from the surface, in contrast to the elongated spigots that project from spinnerets. These minute spigots produce extremely fine fibers, merely tens of nanometres thick, which are combed out by the spider's calamistrum, producing silk with a woolly texture. The fibers are so small in diameter that they are strongly subject to Van der Waals forces. In addition, the fibres have a surface that absorbs waxes from the epicuticle of insect prey on contact. This creates a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneomorphae Families
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:Ch ...

Australian Museum
The Australian Museum is a heritage-listed museum at 1 William Street, Sydney central business district, New South Wales, Australia. It is the oldest museum in Australia,Design 5, 2016, p.1 and the fifth oldest natural history museum in the world, with an international reputation in the fields of natural history and anthropology. It was first conceived and developed along the contemporary European model of an encyclopedic warehouse of cultural and natural history and features collections of vertebrate and invertebrate zoology, as well as mineralogy, palaeontology and anthropology. Apart from exhibitions, the museum is also involved in Indigenous studies research and community programs. In the museum's early years, collecting was its main priority, and specimens were commonly traded with British and other European institutions. The scientific stature of the museum was established under the curatorship of Gerard Krefft, himself a published scientist. The museum is located at t ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene The Eocene ( ) Epoch is a geological epoch that lasted from ...

Alexander Macleay
Alexander Macleay (also spelt McLeay) MLC FLS FRS (24 June 1767 – 18 July 1848) was a leading member of the Linnean Society, a fellow of the Royal Society and member of the New South Wales Legislative Council. Life Macleay was born on Ross-shire, Scotland, eldest son of William Macleay, provost of Wick. Alexander had a classical education, before relocating to London and becoming a wine merchant with his business partner William Sharp – after whom his first son was named. In 1795 he was elected a fellow of the Linnean Society of London, also serving as its secretary, and was also appointed chief clerk in the prisoners of war office. When the office was linked with the Transport Board after war broke out, Macleay became head of the correspondence department and by 1806 secretary. The board was abolished in 1815, and Macleay retired on an annual pension, of £750. Macleay's chief natural history interest was entomology, principally lepidoptery, and he possessed the finest ...

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relati .... , 50,151 accepted species were listed. The order Araneae (spiders) has the seventh-most species of all orders. The existence of the World Spider Catalog makes spiders the largest taxon with an online listing that is updated regularly.
