Last night, I came across this disturbing, yet mesmerizing video of a worm like monster spitting out some weird vein thing and begins to suck on a hand. It's so wrong, yet people are so curious to find out what is this evil thing?

Thanks to Iflscience.com, we now have a better idea on what this nightmare is. According to Reddit user, Exxocet had defined this creature as a ribbon worm, specifically a species called Gorgonorhynchus.

Citing J.F.G. Wheeler's study "The Discovery of the Nemertean Gorgonorhynchus and Its Bearing on Evolutionary Theory", Exxocet tells of the origin of this monster and if you want to know more you can go here. 

As for me, I don't understand these big words, all I understand is that this worm is pure evil as you watch it erupt a nasty white vein like web on to an innocent person and begins to suck it's blood out. I am more concerned about where these horrible things are from.
