You probably recognize these two from television. Ghost Hunters airs Wednesdays on Syfy; Ghost Adventures, Saturdays on the Travel Channel. But their YouTube channels are worth checking out for your streaming scares. Their YouTube channels are great ways to revisit past investigations, even sometimes including silly behind the scenes extras and fan interactions. 
In January 2013, a Canadian student at the University of British Columbia in Vancouver was reported missing, having last been seen at the Cecil Hotel in Los Angeles. After Elisa Lam had been missing for a week and a half, LA police released this video of her last known appearance. Three weeks later, Lam's body was discovered naked and drowned in the building's water tower, and her death was labeled an accident. Her mystery reportedly inspired Ryan Murphy to make American Horror Story: Hotel.
It just looks like a smudge in our still shots, but in motion it's a clear yet transparent human figure, merrily strolling down the path like someone out to test their new Predator cloaking device. The guard tracks it across all four screens as it walks right through the closed gate, crosses the street and then struts out over the river before fading from view:
Lakes are already lurking with scary things, like catfish and smelly algae. But when Kim Davidson was splashing around with her and her pal's three kids in a lake, they never thought in a million years that they would come in contact with something this creepy. After the photo was taken, Kim immediately consulted paranormal experts to find out who the extra kid in the picture was. The experts believe it to be the ghost of a girl named Doreen O'Sullivan, who drowned in that very spot in 1913. Don't know about you, but we'll be swimming in pools from now on.
The goblin shark is, without a doubt, one of the weird ocean animals that looks more like the predators from the thriller shark movies. This living fossil sports a protruding nose or stout to detect its prey. Along with its unique and extendable jaw that appears to unhinge when feeding, the overall appearance of the goblin shark is both fascinating and terrifying at the same time.
Is it just us, or does this frog look like Kermit? There are many different species of glass frogs, but this little guy is a new discovery — the first in Costa Rica since 1973. While its bright green coloring might grab your attention, the coolest part about this frog is that it is see-through. That’s right — the underside is translucent, providing a stunning view of the amphibian’s internal organs. If you want to see one, you’ll have to keep your eyes peeled — these tiny jumpers are less than an inch long.
The Panda Ant is a most unusual species of insect. Their name derives from the obvious resemblance to a panda in its markings. This remarkable insect is not even an ant. The Panda Ant is actually a variety of wingless wasp! Very little is known of this little seen insect. They have been seen to bring down animals as large as cows with only a few dozen stings.
“These small geckos are native to Madagascar. Other leaf-tailed geckos of the genus Uroplatus share a similar flattened tail, but the satanic leaf-tailed gecko has arguably the most leaf-like tail when compared to congeners. This is a fairly old photo, but proves that you can take nice photos with relatively cheap cameras. This was only a 3.2 megapixel Nikon Coolpix 3700…well before I had begun shooting with a DSLR.” – Mike Martin
Approximately 99 percent of "supernatural" videos can be revealed as hoaxes simply by asking "Why was anyone filming this?" As much as Cloverfield and The Blair Witch Project have attempted to convince us otherwise, people usually don't have cameras glued to their faces unless they know someone is about to be shot out of a cannon or something. So that's our question as soon as this video opens:
In this video, we have four kids wandering around looking for a ghost in an abandoned school in Iraq (one description says India, but since they're speaking Arabic we'll go with Iraq). The boys are kind of wandering aimlessly through stairwells and empty classrooms for a solid two minutes, which would arouse suspicion under our "Why is anyone filming this?" rule if not for the fact that we know they are explicitly waiting for the lights to suddenly dim and for a hallway full of disembodied 19th century clothes to start doing the Monster Mash. That doesn't happen. What happens is much creepier:
About Youtuber Horror films often deal with viewers' nightmares, fears, revulsions and terror of the unknown. Plots within the horror genre often involve the intrusion of an evil force, event, or personage into the everyday world. Prevalent elements include ghosts, aliens, vampires, werewolves, demons, satanism, gore, torture, vicious animals, evil witches, monsters, zombies, cannibals and many more.
This isopod crustacean — from the same group as pill bugs — must be one of the most stomach churning of all parasites. These tongue eaters are a huge pest in global fish farms; however, on coral reefs divers can sometimes spot them in an unusual place: the mouths of anemonefishes. All that’s usually visible of this sinister parasite in the anemonefish’s open mouth are the beady, black eyes set on a white head in the place you’d expect the tongue to be. Initially, the parasite grub crawls through the fish’s gills and attaches to the tongue.
“The shoebill (Balaeniceps rex) is one of the most sought after bird in Africa. A most amazing bird with prehistoric looks – its height of up to 150 centimeters (5 feet) and weighs up to 14 pounds – a most amazing bird found in the pearl of Africa – Uganda. The Arabs used to call the Shoebill Stork – “Abu Maruk” meaning father of the shoe – one could call the Shoebill Stork a flying shoe because of his unique bill. Amazingly this prehistoric looking bird can live for 50 some years. The population of the shoebills is estimated at between 5,000 and 8,000 individuals, the majority of which live in swamps in Sudan, Uganda, eastern Democratic Republic of the Congo, and Zambia. BirdLife International has classified it as Vulnerable with the main threats being habitat destruction, disturbance and hunting.” – Manuela Kulpa
This video, uploaded by British water company United Utilities in April 2011, showed three clips of a maintenance robot running across some sort of creature in the sewers under the St. James neighborhood of London. The internet population quickly began wondering if this was some sort of genetic experiment or just an escaped monkey before someone put together that it was April and United Utilities had a “What Not To Flush” campaign running to educate people about proper sewer usage. Yeah, a water company pulled a viral April Fools' Joke that’s still circulated as legitimate. It only lives on because of how creepy it it.
“The leaf-tailed geckos are native to Madagascar and are renowned for their camouflage. This individual is just a juvenile. Many of the leaf-tailed gecko species press their bodies against wooden limbs and trunks during the daytime, and their flattened bodies, fringes, and tails eliminate any shadow, making them invisible to predators. At night, they become active and hunt primarily invertebrate prey.” – Mike Martin
Eunice aphroditois is ingeniously named after the infamous Bobbitt family incident of the early ’90s in which Lorena Bobbitt cut off her husband’s manhood with a kitchen knife. The hunting method of this giant polychaete worm is said to resemble Lorena’s modus operandi. The worm emerges from the silty ocean floor at dusk and waits motionless with its iridescent body standing at attention 6 inches out of the substrate.
You might be surprised to learn that this beautiful sea critter (also known as a sea swallow or blue dragon) is actually a sea slug. The blue and silvery mollusk is known to feed off cnidarians like the venomous Portuguese Man o' War. What makes these gorgeous slugs even more fascinating is their practice of storing the cnidarians's stinging nematocysts within its own tissues — ensuring a painful sting to anyone who messes with it.
It’s been nearly a decade since it was first uploaded, but “I Feel Fantastic” is still only a little less mysterious than when it first captured the attention of the internet. The featured robot, Tara the Android, is the creation of an robot hobbyist who calls himself "John Bergeron." The plan was for Tara to be the first android pop star, but the bizarre description on the YouTube upload that references Pygmalion and a cutaway from I Feel Fantastic to an outdoor location gave birth to several online urban legends. Is Tara a harmless pop star, or a robot built in the image of a murder victim?
Kiwa hirsuta, which has been nicknamed the yeti crab (for obvious reasons), is a crustacean that was discovered back in 2005 900 miles south of Easter Island at a depth of 2,300 meters. Although there isn't a great deal of information on these curious animals, they seem to dwell around deep sea hydrothermal vents. As you can see, their pincers are covered with blond, hair-like strands. It transpires that these hairs are riddled with bacteria, which some believe may serve as a food source for the crustacean. 
If you freeze-frame it, you can see that while the thing may be humanoid in appearance, its eyes are badly sunken in, its head and face seem overly large (and awfully pale), and its pupils catch every ounce of the virtually nonexistent light coming from the camera. So, it's either a seriously haggard meth addict with Riddick-like powers who wandered out into the woods of Spain to scream at the talking scorpions living beneath his fingernails, or it's someone in heavy monster makeup. Most likely, it's the latter and the whole thing was staged by a couple of friends wanting to either get on the news or become Internet famous. It's not even that great of a costu- ... wait, what are those, stumps on its back?

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.
A young boy is sleeping in his bed on a usual night. He hears footsteps outside his door, and peeks out of his eyes to see what is happening. His door swings open quietly to reveal a murderer carrying the corpses of his parents. After silently propping them up on a chair, he writes something on the wall in the blood of the dead bodies. He then hides under the childs bed.

YouTube user Exploring Abandoned Mines is known for exactly that - exploring abandoned mines. So when he ran into something strange while exploring the Horton Mine in 2013, it was a surprise to all. Upon returning in 2014, he experienced strange machine sounds, an unearthly mist, and what sounded like a woman on a PA system warning of an incoming detonation. While there's not much to see in the video beyond the interior of an old mine, the audio is quite scary - just clear enough to be understood, but just out of place enough to send chills up your spine.
Sadly, in the wild, axolotls are on the brink of extinction. They’re found only in local waterways near Mexico City, where urbanization and water pollution have exacted a toll on their population numbers. Compounding these environmental hazards are nonnative fish species such as Asian carp and African tilapia, which eat juvenile axolotls. These amphibians, which are popular in home aquariums, can be nearly black, chocolate brown, golden, cream colored, speckled or piebald.
The Mutillidae are a family of more than 3,000 species of wasps (despite the names) whose wingless females resemble large, hairy ants. Found in Chile, they are known for their extremely painful stings, hence the common name cow killer or cow ant. Black and white specimens are sometimes known as panda ants due to their hair coloration resembling that of the Chinese giant panda. (Image credits: Chris Lukhaup)

So that's our question as soon as this video opens:

Evolution, I just have a few questions. And they all have to do with why this fish looks oddly like my Grandpa Tom. Also, who was so lazy that they decided on ‘blobfish’? Honestly, I could write an entire book of questions, but for now, I’ll just admire the laziness of the blobfish, who doesn’t work for food and rather just inhales whatever floats by that looks generally edible (yes––that’s true).

“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
