Viral Video Captures Spiders 'Raining' on Brazil

How about glancing up and seeing thousands of spiders swaying and dangling in the sky? That's what Erick Reis, 20, witnessed when leaving an engagement party in the Brazilian town of Santo Antonio da Platina—so he shot a video that has since gone viral, the Examiner reports. Turns out the phenomenon is not uncommon, as the Anelosimus eximius spider likes to build webs big enough to fit thousands. Winds sometimes carry the webs and drop them in new locales in a so-called "spider rain." So, despite appearances, it's really the spiders who are scared. (But see where a mysterious swarm of spiders left two dead.)
