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.

Scientists at the Australian Museum reported they’ve discovered a new species of spider, and it’s so deadly that just one bite is all it takes to kill a fully-grown adult human.

“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.

There are several genera of funnel web spiders, but the most common ones in Australia are Atrax, Hadronyche, and Illawarra. They vary in size and color, usually black or brown, with shiny carapaces. The males are generally smaller and less robust than the females.

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'

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

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,
