Missulena
''Missulena'' is a genus of mygalomorph spiders in the family Actinopodidae. It was first described by Charles Walckenaer in 1805, and is a senior synonym of ''Eriodon''. ''M. tussulena'' is found in Chile, but the rest are indigenous to Australia. They are sometimes referred to as "mouse spiders" from the now-disproven belief that they dig deep burrows similar to those of mice. ''Scotophaeus blackwalli'' is also called a "mouse spider", but it is smaller and not closely related. Description These spiders are medium to large in size, ranging from . They have a glossy carapace and high, broad heads with eyes spread out across the front of the head, and short spinnerets in the rear of the abdomen. They mostly prey on insects, though they may consume other small animals as opportunity presents. Their primary predators include wasps, centipedes, and scorpions. These spiders also exhibit sexual dimorphism. Females are entirely black, while males coloration is specific to eac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Missulena Occatoria
''Missulena occatoria'', known as the red-headed mouse spider, is a species of spider found in Southern Australia, from open forest to desert shrubland. It is the largest (females up to 24 mm, males up to 12 mm) and most widely distributed ''Missulena'' species, because the spiderlings are wind-dispersed (ballooning). Normally this only occurs with araneomorph spiders, mygalomorph spiders normally disperse by walking. ''Missulena'' venom may be very toxic, but few cases of serious envenomation have been recorded. Most recorded bites only caused minor effects, with Australian funnel-web spider antivenom having proved effective as a treatment.Australian MuseumRed-headed Mouse Spider, ''Missulena occatoria''/ref> The spiders dig a burrow up to 55 cm deep, with two trapdoors. While the females are black with a red tinge, the males have a bright red head and jaws, and a gunmetal blue-black abdomen. Taxonomy ''M. occatoria'' was first described by Charles Athanase Wa ...

Missulena Bradleyi
''Missulena bradleyi,'' also known as the eastern mouse spider, is a species of spider belonging to the family Actinopodidae. The spider is endemic to the eastern coast of Australia. William Joseph Rainbow described the eastern mouse spider in 1914 from a specimen collected in North Sydney by Henry Houghton Burton Bradley (1845–1918), president of the board of trustees of the Australian Museum at the time. Describing the "beautiful and strikingly marked" specimen as a "decided novelty", Rainbow named it in honour of its collector, whom he stated was the first collector of Australian spiders. Eastern mouse spiders are often mistaken for Australian funnel-web spiders. The females are large and very strong, with powerful chelicerae.Missulena bradleyi Rainbow, 1914 Bradley's Mouse Spider http://www.arachne.org.au/01_cms/details.asp?ID=2587 Their fangs often cross over slightly, while those of Australian funnel-web spiders remain parallel, and the latter often have a drop of venom ...

Actinopodidae
Actinopodidae ( Mouse spiders) is a family of mygalomorph orb weaver spiders found in mainland Australia and South America usually in open forest. Species are most common in Queensland, Australia. It includes mouse spiders, whose bites, though rare, are considered medically significant and potentially dangerous. Description Actinopodidae has wider vision then most other Australian mygalomorphs and have a wide front to there carapace. Mouse spiders are stout black with species size varying from 10 mm-35 mm in length. Species have distinctively bulbous heads and jaw regions. Mouse spiders are oftentimes confused with funnel-web spiders. Depending on the species, the abdomen is black or dark blue with a light grey to white patch top. Legs are dark and may appear thin and the head is shiny black. Female of the family are stockier and larger. Burrow Mouse spiders live in soil covered burrows with a hinged top. Burrows can extent to a depth of 30 cm (12 inches). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Funnel-web Spider
Atracidae is a family of mygalomorph spiders, commonly known as Australian funnel-web spiders or atracids. It has been included as a subfamily of the Hexathelidae, but is now recognized as a separate family. All members of the family are native to Australia. Atracidae consists of three genera: ''Atrax'', '' Hadronyche'', and ''Illawarra'', comprising 35 species. Some members of the family produce venom that is dangerous to humans, and bites by spiders of six of the species have caused severe injuries to victims. The bites of the Sydney funnel-web spider (''Atrax robustus'') and northern tree-dwelling funnel-web spider (''Hadronyche formidabilis'') are potentially deadly, but no fatalities have occurred since the introduction of modern first-aid techniques and antivenom. Description Spiders in the family Atracidae are medium to large in size, with body lengths ranging from 1 to 5 cm (0.4 to 2.0 in), with one exceptional specimen reaching 8 cm (3.1 in). They have ...

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the branching ...

Centipede
Centipedes (from New Latin , "hundred", and Latin , " foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', lip, and New Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful bites, injecting their venom through pincer-like appendages known as forcipules. Despite the name, centipedes can have a varying number of legs, ranging from 30 to 382. Centipedes always have an odd number of pairs of legs; no centipede has exactly 100. Like spiders and scorpions, centipedes are predominantly carnivorous. Their size ranges from a few millimetres in the smaller lithobiomorphs and geophilomorphs to about in the largest scolopendromorphs. Centipedes can be found in a wide variety of environments.

Mouse Spider02
A mouse ( : mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (''Mus musculus''). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term ''mouse'' if it is smaller, or ''rat'' if it is larger. The common terms ''rat'' and ''mouse'' are not taxonomically specific. Typical mice are classified in the genus ''Mus'', but the term ''mouse'' is not confined to members of ''Mus'' and can also apply to species from other genera such as the deer mouse, ''Peromyscus''. Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable to breeding and ...
