What makes spiders deadly?
Almost all spiders are venomous; only two small families lack venom glands. The purpose of spider venom is to subdue the spider’s prey, almost always insects. A minority of spider species have venom that can cause localized pain in humans, like the venom of bees or wasps.
Has anyone been killed by a spider?
Severe bites have been attributed to members of the genus Macrothele in Taiwan, but no fatalities. In other mammals, such as rodents, for example, the effects of funnel web spider venom are much less severe. Funnel web spiders are related to other mygalomorphs such as tarantulas and trapdoor spiders.

Why are funnel web spiders so dangerous to humans?
Funnel webs are considered one of Australia’s most fearsome spiders, but their ability to kill humans is by accident rather than design, our new research shows. In findings published today, we reveal how the highly toxic and quick-acting venom of male funnel-web spiders is likely to have developed as a defence against predators.
