Scariest Things Seen Under a Microscope is a 10-minute video where you can learn about some of the tiny creatures that look the most terrifying when viewed up close.
It's amazing to think that these creatures are crawling around the earth with us, but are invisible to the naked eye.
I found creature number 9 to be the creepiest. It looks like a horned slug-monster with a bird beak full of sharp teeth. I am thankful that there aren't giant versions of these things roaming the earth, but it's incredible that we share a planet with these surreal looking organisms.
