This is the kind of creature that came straight out of your nightmare to suck your soul out! But this deep sea fish lives in depths which have little or no light penetration at all. Because of this, their eyes are adapted to recognize even the slightest shadows in the water. Believe it or not, these creatures have the ability to create a light of their own through a phenomenon known as bioluminescence and sometimes they can actually adjust the level of light below them to match the surface light, which makes them practically invisible! Scary indeed!
Also known as "thumb splitters," these vibrant crustaceans are named in honor of their powerful claws, which can spear, stun and dismember prey with 200 pounds of force. In addition to their predatory tendencies, mantis shrimp are also distinguished for their impressive visual capabilities. The eyes of these psychedelic sea critters are equipped with 12 color receptors — meanwhile, humans and most other animals only have three. Scientists speculate this might enable them to process color information quickly within the eye instead going through the brain.
A headless goddamned ghost appears right in goddamned front of them. You literally see it materialize on camera -- of all the entries on this list, this is the one you absolutely have to watch (here's a shorter version that cuts right to the ghost if you don't have 4 free minutes). Seriously, your mind will be blown like Eric Stoltz's penis in The Rules of Attraction. As they swing the camera lazily through the room, the ghost just walks very purposefully toward them like it's delivering a pizza, while a long, low moan emanates from its phantom lungs.
