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.
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.
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. 
Intrigued by the incredible—and often inexplicable—forms of life on our Earth, science writer Mara Grunbaum began showcasing her favorite examples on Tumblr. Now you can marvel at more than 100 of Evolution’s greatest hits and misses in her new book WTF, Evolution?!: A Theory of Unintelligible Design (Workman). Take a break from these strange creatures and check out the most adorable photos of the sweetest animals. 

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.
For instance, in 2015 researchers identified a ruby-red sea dragon off the coast of Australia, a new species of giant tortoise in the Galápagos Islands and an ancient spikey worm with 30 legs in China. As these newfound creatures are uncovered, it's important to protect them from pollution, habitat loss and the havoc caused by invasive species, especially as Earth enters its sixth mass extinction, experts say.
Watch through Blair Witch vision as some poor soul gets hopelessly lost in the subterranean stone tunnels of the Paris catacombs, and listen to him get more frightened as he speeds up his winding path (like he's being chased?) before the camera cuts out (was it dropped?). Then we hear the man either run off or get sucked into the spirit world. You watch and decide... if you're not claustrophobic, that is.
Nurul Islam, 37, was enjoying the afternoon with his niece, Mayrian Islam,11, and nephew, Ryhan Kaliq, 9, and snapping pictures in front of a fake Victorian-style ruin when suddenly a "ghost" appeared out of nowhere. At first, Nurul didn't think it could possibly be an apparition. But, then again, he also says he made sure all the other tourists were out of the way before he snapped this shot. 

Check out these humongous dudes. Sunfish, or mola mola, are huge bony fish that can weigh up to a whopping 2,250 kilograms and can reach around 4 meters in length. Their rather odd appearance is due to the fact that their back fin doesn’t grow and instead folds into itself. They typically feed on jellyfish and small fish, and can be found in both temperature and tropical oceans.
And the light from the "angel" has a strange weight to it -- you can see it pulse outward at the bottom as it suddenly gains mass after striking the ground. Anyway, maybe a Pixar animator got bored and threw this together just to mess with people. After contacting all of his or her friends in Jakarta, Indonesia, to stage it. Including, of course, his or her friends with access to the security footage of that particular public square.
Is it art? Is it someone who is just incredibly disturbed? Is it some sort of narrative that we’re missing? The YouTube account for Robert Helpmann includes several videos of “Daisy” who appears to be a mannequin taped up in a garbage bag that is treated like a human (initial shock was generated by people mistaking Daisy for a corpse). The most popular and disturbing of these videos, which started appearing in 2015, is “Daisy Unwinds” where Daisy is “fed” and thanks to the glory of low quality video, it’s hard to tell if the mannequin is actually eating or not.
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 a video begins with a couple of guys crashing through the woods at night like one of those "searching for Bigfoot" specials on The History Channel, you can already tell that it isn't going to end well (and that they aren't going to find Bigfoot). That's the case with this video, reportedly shot in the woods of Catalonia, Spain (hence all the Spanish):

Not content with only one platform, we’re committed to montages from Vine, Twitter, Instagram, Facebook, Snapchat, and Musically. Sit back and enjoy a veritable fail army: kids fails, animal fails, girl fails, trampoline fails, car fails, on the job fails, old people fails, school fails, water fails, prank fails and pranks gone wrong, funy fails and more!
Despite its ferocious demeanor, the fangtooth measures a little more than 6 inches in length as an adult. Juveniles and adults look so much different that in the 1800s they were thought to be distinct species. Juveniles are found as shallow as 150 feet, migrating into the depths as they mature. It is believed that males are parasitic of females and attach permanently onto them to fertilize the eggs.
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.
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.
User the15experience uploaded with the simple description: "This video was sent to me anonymously. I do not have any information beyond that. It is for you to decide on your own whether it is real or fake." The video was so shocking when it was uploaded that it launched an online search for this woman, which eventually uncovered the truth. It turned out that the original teaser had been clipped to remove the "15 Experience" URL at the end and made it to Facebook as a "real" paranormal video. Don't worry, "Nikki" is fine.
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.

Known for the peculiar frill around its neck, this lizard is largely arboreal, spending majority of its time in the trees. When the lizard is frightened, it produces a startling deimatic display: it gapes its mouth, exposing a bright pink or yellow lining; it spreads out its frill, displaying bright orange and red scales; raises its body; and sometimes holds its tail above its body. This reaction is used for territorial displays, to discourage predators, and during courtship.
