Parasitic Worm VIDEO Shows Huge Nematode Emerging From Dead Spider Host, Biologist Says 

When YouTube user Brent Askwith saw a freakishly large worm slither out of a spider he had just killed, he recorded the ghoulish event and appropriately named the video "WTF IS THIS?!?" 
"I was just editing my latest montage and this huge spider came out, so I sprayed it and killed it, then this fricken alien worm came out," Askwith wrote in the video's description. 
That "alien worm" is actually a parasitic nematode, also known as a roundworm. While the nematode in the YouTube video is larger than most, Harvard University entomologist Dr. Brian Farrell told The Huffington Post that every human is infested with thousands of tiny nematodes. 
"Most have no obvious effect on us, and we are mostly unaware of their presence," he wrote in an e-mail, "but a few are large enough to cause diseases such as trichinosis."
