If the title didn’t give it away, this piece is not for the squeamish or faint of heart. Sure, we won’t be talking gory details, but spiders have the unfortunate reputation of being one of the most feared or hated critters on the planet. And now scientists have just given haters even more ammo. According to research, which admittedly involves a lot of estimating, spiders eat somewhere between 400 to 800 million tons of prey a year. Which is pretty big considering there are believed to be only 25 million tons’ worth of spiders on the planet.
