So what is it? It's clearly a person (or the shade of a person) just kind of jaunting along like a haunted iPod commercial, but what could produce that image on the security feed? A lot of YouTube comments jump to the conclusion that it's a reflection on the monitor, which would make sense if the room the monitors are in were about 60 feet long, and wide enough for someone to stand far enough away to make the appropriate scale and to walk a long enough distance to cast a seamless reflection on all four screens. Beyond that, the screens are stacked, not side by side, meaning the security office would have to be two stories tall and the person casting the reflection would have to teleport from the top level to the bottom level midstride in order to maintain the illusion. Either that or the reflection is being made by a very tiny man.
While most people will likely never see a ghost in real life, haunted recordings purportedly showing ghostly figures actually exist. Some people believe it's easier to capture ghosts on film due to energy impressions or the ability of a camera to capture a single moment in time, and it's easier than ever to share these real recordings of ghosts online thanks to YouTube, Reddit, and other social media. These videos, taken in multiple places throughout the world, feature strange appearances and events that are tough to explain without a supernatural influence.
It almost looks like it could be viral marketing for something like Diablo III or a new season of Supernatural, but the footage has been floating around for over a year now and so far no one has claimed it. One part of your brain knows this is just a computer-generated effect. But goddamn, did they do a good job -- notice how the glow from the flaming angel beast even lights up the structure on the opposite side of the frame:

Thorn bugs have interested people because of their unusual appearances. These deceptive insects, which are related to cicadas and leafhoppers, have developed enlarged and ornate pronotums, which resemble thorns on a branch. Not only does this aid in camouflaging them to look like a part of the plant they’re resting on, but it also discourages predators of both the bugs and the plant from taking a bite from fear of getting pierced.

This video, conducted mostly in American Sign Language, finds a man claiming that he keeps his great grandmother's casket in his backyard. Apparently, the original cemetery "cannot upkeep because of corruption," so he transferred his grandmother's body to an above-ground lot. Not only is this very illegal (do not keep dead bodies, y'all), the next video clip involves the man opening the casket and kissing the corpse of his grandmother on the mouth. ON. THE. MOUTH.
When they hatch, they quickly infect other local anemonefishes. Parasites, by definition, don’t aspire to kill their host. After all, if the host dies, the parasite loses its home and food source. However, in the case of the tongue-eating louse, some individuals can grow to be so large that the hapless anemonefish struggles to close its mouth. Eventually, as you might imagine, this hinders the host’s ability to eat.
The daintily named sea pig is actually a kind of locally abundant sea cucumber that inhabits the world’s abyssal plains up to 3.7 miles beneath the surface. It gets its name from a characteristic pink, eggplant-shaped body and bloated legs that give it a porcine appearance. Like their shallower cucumber cousins, sea pigs play an important role in marine ecosystems. They feed on detritus that falls to the seafloor from the rich waters above, whether plankton or a whale carcass. They walk along on a few large tube feet, using a combination of muscle contractions and body fluids. Modified pairs of legs can act as antennae to detect food.
