Pacu is actually a common name for numerous different fish species that are related to piranhas. Pacus are vegetarian fishes that are traditionally found in the major river systems of South America. They look a bit like a piranha, but they’re usually a lot larger than your average piranha. So what’s so interesting about these fish, they look pretty uninspiring- right? WRONG.

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.
In this news video, a child appears to be haunted by a duppy, a malevolent spirit of Caribbean origin. While the boy in the video claims the duppy is the spirit of a friend, it behaves violently toward him, pushing and pulling him in different directions. Some people have written off the video as a fake, but watching the boy's movements carefully, especially in the second attack, shows him flailing and kicking in ways that don't look like acting. Without follow-up, we don't know whether the spirit ever left him alone or if he continued to be haunted - we're left only with the lasting image of a young boy tormented by a violent duppy.
Uploaded by chestertyler714 in 2009, Real Demons Caught On Tape, is a special effects showcase of a very high skill level. Back in 2009, the consumer technology easily existed to make an ashy hand ghost jump scare YouTube video. The four million views that the video has accumulated since means more than enough people were willing to go along with the creepiness all the way to the denouement of a monster. Sometimes this sort of thing could even get a person a job, like when Lights Out was all the rage.

From the side, this mole only looks a bit odd, but seen head-on, it can be quite startling. It is considered by numerous people to be incredibly ugly with its odd tentacle-like nose. In reality, the 11 pairs of appendages on the snout are quite amazing. They contain over 25,000 sensory receptors which are called Eimer’s organs. This is the critter’s main sensory apparatus, and it is so fine-tuned that scientists believe it can detect seismic waves. There’s nothing really ugly about the star-nose mole. It’s just different, and its own weird way, quite cute.

It’s the most wonderful time of the year: Halloween! And the only thing more fun than celebrating with a "sexy [insert inanimate object here]" costume and downing candy corn shots is not doing that and instead downing something pumpkin-flavored under a pile of blankets while watching some truly terrifying content. If you’re stuck for ideas, here are 13 of our favorite (read: scariest) classic ghost movies guaranteed to keep you up all night thinking, What was that? Did you hear that?! TURN THE LIGHTS ON.
“This is a maned wolf from the Piaui State of northeastern Brazil. It is the tallest wild canid in the world standing over 4 feet at the shoulder. Due to its red fur and fox-like face and ears, it is often called a fox on stilts. This particular wolf came sniffing around our camp the previous two nights but I was hoping to photograph it in existing light without flash. Maned wolves are mostly nocturnal but will forage in the morning and late afternoon and finally on the third night it came by early enough that I was able to get a bunch of shots before dusk.” – Sean Crane
