Scientists in Australia have discovered a ‘giant’ species of Sydney funnel-web spider, one of the world’s deadliest. Nicknamed ‘Big Boy’, the species was originally found by Kane Christensen, a spider enthusiast and ex-head of spiders at the Australian Reptile Park. in the early 2000s near Newcastle, 170 km north of Sydney.

A new, in-depth study of the spider has discovered that what we thought was one species is actually three. That means there are two new species of the world's most venomous spider, but the discovery is actually good news: it will allow scientists to better characterize and understand the venom each species produces.
