It's October now, so of course you are looking for spooky films to watch. Here's one about a shape-shifting vampire, or a whole family of vampires, that are out to suck the life force from their victims. Well, they are amoebas, but if you were scaled down to their size, they would be terrifying. These microbes are voracious, and their feeding habits are so like the cinematically familiar "bite and suck" method that they were named Vampyrellida. Leave it to the folks at Journey to the Microcosmos to teach us about amoebas by making them the stars of a horror film. -via Geeks Are Sexy
