==Description== Spiders in the family Atracidae are medium to large in size, with body lengths ranging from {{convert|1|to|5|cm|in|abbr=on}}, with one exceptional specimen reaching {{convert|8|cm|in|abbr=on}}.<ref>{{Cite web|date=12 November 2021|title=Press Release: MEGASPIDER β "What nightmares are made of!"|url=https://us14.campaign-archive.com/?u=3cb5d1db2eba822be67e2c3fb&id=dde2d75c2f|url-status=live|archive-url=https://web.archive.org/web/20211116060642/https://us14.campaign-archive.com/?u=3cb5d1db2eba822be67e2c3fb&id=dde2d75c2f|archive-date=16 November 2021|access-date=21 November 2021|website=[[Australian Reptile Park]]}}</ref> They have a hairless carapace covering the front part of their bodies. Some atracids have relatively long [[Spinneret (spider)|spinnerets]]; this is especially true of the Sydney funnel-web spider (''A. robustus''). Males have a large mating spur projecting from the middle of their second pair of legs.<ref name=ausmus/> Like other [[Mygalomorphae]] β an [[infraorder]] of [[spider]]s that includes the tropical [[tarantula]]s<ref>Mygalomorph tarantulas are a different family from the original 'tarantula', an araneomorph lycosid from Europe. βRod and Ken Preston-Mafham.

They have ample venom glands that lie entirely within their [[chelicerae]]. Their fangs are large and powerful, capable of penetrating fingernails and soft shoes.<ref>[https://web.archive.org/web/20130528170428/http://education.nationalgeographic.com/education/media/funnel-web-fangs/?ar_a=1 Funnel-web Fangs] ''National Geographic''. Retrieved 4 May 2014.</ref> Australian funnel-web spiders make their burrows in moist, cool, sheltered habitats β under rocks, in and under rotting logs, and some in rough-barked trees (occasionally meters above ground). They are commonly found in suburban rockeries and shrubberies, rarely in lawns or other open terrain. A burrow characteristically has irregular silk trip-lines radiating from the entrance.<ref name=ausmus/> Unlike some related [[trapdoor spider]]s, they do not build lids to their burrows.
