Your worst nightmare just got faster. Researchers have confirmed what arachnophobes everywhere hope never to experience: the huntsman spider, native to Queensland, Australia, can run you down. At nearly 3.6 meters per second—just over 8 miles per hour—this eight-legged sprinter leaves the average human in the dust, which tops out around 4-6 miles per hour. So much for outrunning your fears.
For years, the Moroccan flic-flac spider held the title of fastest arachnid, but that crown came with an asterisk. Scientists weren’t convinced because the flic-flac uses acrobatic flipping movements to boost its speed—a technique that felt like cheating the speed rankings. To settle the question once and for all, researchers tested 258 spider species in controlled laboratory conditions. The huntsman spider emerged as the clear victor, leaving no doubt about its dominance on the speed charts.
What makes the huntsman spider so devastatingly quick? The research uncovered a simple formula: size matters, but only to a point. Large spiders run faster than their smaller cousins, but there’s a limit—if the abdomen gets too heavy, it becomes a drag on performance. Long legs, meanwhile, are a huntsman’s secret weapon. The combination of modest size and impressive leg length creates the perfect sprint machine.
So where does this leave arachnophobes? The consolation prize is small: huntsman spiders prefer hunting insects and other small prey, not humans. But if you ever find yourself face-to-face with one in Queensland, Australia, know that your jogging pace won’t save you. Your best bet? Stay indoors.
