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,

“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.

A new species of funnel-web spider has been discovered in Newcastle, Australia - even larger and more venomous than common Sydney funnel-web spiders.

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.
