This claim is untrue. Peacock Spiders (Maratus spp.) Research by toxicologist Geoff Isbister and arachnologist Mike Gray investigated verified Lampona cylindrata bites, patients complained about pain, redness and itchiness, but researchers could find no resulting necrotic ulcers or other confirmed infections. For humans though they are completely harmless. [13] The most obvious sign of a Redback bite is extreme pain accompanied by localised sweating, beginning three to five minutes after being bitten. These Australian jumping spiders may be small, but they are also the most spectacular, colourful and high energy spiders in the world. Over a ten year period in which I have handled dozens of species, thousands of times, I have not seen the slightest inclination by any individual to bite me or anyone else who handled them. [15][16] Lamponidae has nearly 200 known species, all but two in Australia. All members of this genus share a similar reputation for inflicting unpleasant and sometimes fatal bites on humans. Chrissy Teigen gives first interview since pregnancy loss. Peacock spiders and other jumping spiders use internal hydraulic pumps rather than leg muscles to leap 30 times their body length. Over a ten year period in which I have handled dozens of species,  thousands of times, I have not seen the slightest inclination by any individual to bite me or anyone else who handled them. P. metallica is also known as the Gooty sapphire ornamental tree spider, Gooty sapphire, and Gooty tarantula. How man species were known when you found your first . The male M. plumosus is also the most atypical of the group, with feathery plumes that it extends to the rear above its elevated and partly expanded fan. Their fans are flaps and fringes on the sides of the abdomen, normally folded away, are inflated and spread wide when displaying. All males in the group extend legs III, but several (M. avibus, M. bubo, M. caeruleus, and M. madelineae) closely bracket the fan with legs III as they display. The fimbriatus group has been found at a number of locations in the grazed interior of New South Wales. Once the Redback is fully trussed, the Daddy Long-legs Spider bites at will and simply waits for the bigger spider to die so it can feed. A number of the spiders were named after people who discovered them. Some wander into houses or fall into swimming pools, where they can stay alive underwater for long periods. The collectors of that time included Eduard Daemel (1821–1900) entomologist, trader, explorer and collector; and Amalie Dietrich (1821–91) who spent 10 years in Australia collecting specimens for the Museum Godeffroy in Hamburg. The cigar-shaped abdomen (sometimes flattened) is narrowed at both ends. Presently the Australian peacock spiders are assigned to two genera, Maratus Karsch 1878 and Saratus Otto & Hill 2017. Of these 9 families are mygalomorph spiders, the remaining araneomorphs. Like other spiders peacock spiders possess venom and they use it to kill their prey, small flies, moths and other insects. Do males display only to a female of their own species ? Peacock Spider males extend brilliantly coloured fans and wave their legs in a display for their female partners. The chrysomelas group includes the widely distributed M. chrysomelas and the closely related M. nigromaculatus that is known only from the southern coast of Queensland. Studies of verified Lampona bites have not shown any case of necrotising ulcers. [5] A Field Guide to Spiders of Australia published by CSIRO Publishing in 2017[3] 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 [6][7][8][9]. He described around 200 new species of spiders. This species has been milked for research at James Cook University Cairns for use in cancer treatments. They have very small fangs which they use to … These spiders are quite different from any other known Maratus, and their display includes the use of extended legs I. Isbister et al. The discovery and later rediscovery of M. harrisi by Stuart Harris was the subject of an award- winning documentary entitled Maratus: A Documystery. P. metallica has been bred in captivity for ten years and is popular with tarantula enthusiasts. Spitting spiders spew silky glue from their venom glands to pin down other, larger spiders for a killing bite to the leg. [3], The urban myth originated in 1982 when Australian medical researcher Struan Sutherland claimed the White-tailed Spider as the culprit of severe skin ulcers and necrotic lesions. The anomalus group includes relatives of M. anomalus that can be distinguished by the presence of a blunt, bifurcated apex of the outer ring of the embolus above a shorter, sharply pointed inner apex of the male pedipalp. Systemic effects such as feeling sick, abdominal pain and nausea can be brought on by trauma and associated pain. [12] The Redback performs sexual cannibalism during mating, the female eating the male who sacrifices himself. It is found within a 100 km diameter circle around Sydney. Males of all three species have a large, fringed fan with distinctive figures consisting of pigmented scales on a background of iridescent scales.

Dr Jurgen Otto If he's not doing it right the female might think he's not the right partner. Their fans are flaps and fringes on the sides of the abdomen, normally folded away, are inflated and spread wide when displaying. Males wander at night in spring and summer in search of females. The Katipo Spiders belong to the worldwide genus Latrodectus, more commonly known as the widow spiders. The female epigynum has heavily sclerotized (darker) ducts at the lateral and medial posterior margin of each fossa. Other common names are metallic tarantula, peacock parachute spider, or peacock tarantula. The calcitrans group is widely distributed in eastern Australia with many colourful species. The two central front eyes of the jumping spider are much more advanced – large, fronted by spherical lenses, with an internal focussing mechanism and complex four layered retina. The middle two eyes in the back row are oval shaped and often silvery or blueish. Legs are slender, with two claws, usually more slender than those of the similar Gnaphosidae.
