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.

Now scientists in Australia have discovered a new funnel-web spider which is even bigger and more venomous. Kane Christensen is behind the discovery and says "its venom glands are a lot larger and its fangs are a lot longer". The new species has been named Atrax christenseni after the man that discovered it.
