Researchers say they used anatomical and DNA comparisons to study different populations of the Sydney funnel-web spider – one of the world’s deadliest spiders – and found there were three species, only two of which were previously known to science.

“The Newcastle funnel-web, Atrax christenseni— dubbed Big Boy—is a totally new species. The ‘true’ Sydney Funnel-web, Atrax robustus centres on the North Shore of Sydney and the Central Coast, and the Southern Sydney Funnel-web, Atrax montanus, is a resurrected species name from 1914,” Loria explained.

Although its venom is the deadliest in the world, no one in Australia has died of a funnel-web bite since the introduction of an antivenom in 1981, despite the 30 to 40 recorded funnel-web bites every year. This is because the antivenom is an excellently effective treatment – but the new discovery could help tweak it.

Australian scientists have discovered a bigger, more venomous species of the Sydney funnel-web spider, one of the world's deadliest.

The first person to discover the Aussie spider, Kane Christensen, has warned people not to approach it, citing its massive fangs and glands that produce 'copious amounts of venom'

Australia's reputation for venomous spiders comes partly from the deadly Sydney funnel-web. It turns out there is not just one species, there are three.

By Shreya Dasgupta The Sydney funnel-web spider, a highly venomous arachnid found crawling in and around Australia’s most populous city, was long thought to be a single species. But it’s actually three different species,
