Unlike most jellyfish, Stygiomedusa gigantea actually has no tentacles — only four “arms” that hang down like wavy curtains. This deep-sea jellyfish has arms that can reach 30 feet in length and also function as extensions of the mouth. Although they do not sting, they are believed to capture and trap plankton and small fish. Stygiomedusa gigantea has been sighted only about 100 times in the past 118 years.

We can truthfully say that our list comprises of some of the rarest and weirdest animals there are. Take, for example, the Glaucus Atlanticus – an aquatic animal who looks like a Pokemon monster and has a name as equally anime. Or the absolutely stunning, yet very unusual animal called Okapi, that looks something like a cross between a moose and a zebra but is actually related to a giraffe. Or even the rare animal called Goblin shark, who looks like it soaked in a bath for too long, making it one of the scariest sea creatures.
'Do you know anybody with Asperger Syndrome?' - Ha, me apparently, who knew - 52 years bewilderment, 35 years seeing Drs for depression & anxiety, not even 1 suggested AS, maybe assumed it was 'males only'. To me AS are the smart, creative, kind, thoughtful, open-minded, honest, cool type I always gravitate to - only a problem with social guff & only 'cos NTs are so rigidly intolerant & accidentally ignorant. No cure for genius.
Something like a nocturnal koala-tarsier combo, the aye-aye has to be the strangest primate you thought up, Evolution. Not sure why you gave it sparse, wirey hairs when you had a great opportunity to make it cute, but we’ll just assume that every part of the aye-aye plays a role in its adaptation to its environment. Now, off to find more weird animal photos! Check out these 6 other nocturnal animals that are rarely seen by humans next.
A spine-chilling classic, M. Night Shyamalan’s debut is about a little boy (Haley Joel Osment) who sees dead people, and a psychologist (Bruce Willis) who tries to help him while coping with his own ghosts. If you’ve managed to remain unspoiled for one of the most iconic twists in movie history, congrats! Enjoy. (Also, who are you?) If not, watch anyway. The movie actually takes on a whole new layer of meaning when you watch it knowing the ending.

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)
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.
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.

This strange blue creature may look like a monster from a Japanese RPG, but it actually is a real animal—the Glaucus atlanticus, sea slug, to be exact. Known as the blue dragon, this creature is a is a species of blue sea slug. You could find it in warm waters of the oceans, as it floats on the surface because of a gas-filled sac in its stomach. The blue dragon is an aggressive predator that feeds on organisms much larger than itself, including the venomous Portuguese man o’ war. Not only that, it actually absorbs the man o’ wars venom and stores it in the tips of the finger-like appendages on either side of its body to use when preying on other fish! So small but so vicious.
The blackness of our deepest oceans is a tough place to eke out a living. To survive, residents must make the most of feeding opportunities when they arise. The black swallower is ruled by its stomach: It can eat fishes twice its own length and 10 times its mass. However, its eyes can be bigger than its stomach. Many of the known specimens have been found when a bloated swallower washed ashore having eaten a meal too large to digest.
If this is all an accident of the lighting and their shitty cell-phone cameras, then it was a lucky damned accident, considering they were specifically there to hunt ghosts in what they thought was a haunted abandoned building. If they doctored the video with effects later, then this is a remarkably subtle job. These are giggling teenagers goofing around, and we're pretty sure they gave us a creepier ghost effect than any of the Paranormal Activity movies. So good job, guys -- you successfully creeped us out, one way or another.
According to one Imgur user, the ghost of our first president appears to have recently showed up on a bedroom wall. "Didn't believe my girlfriend when she said she saw a face on the wall," Imgur user Mahurtma wrote on the post. "Then I took a picture of it." Some Imgur commenters think it's the spirit of Albert Einstein, while others are sure it's definitely George Washington. Either way, those are two pretty cool ghosts to be haunted by, right?
​Galeopterus variegatus, also named Sunda Colugo or the Sunda Flying Lemur, is a nocturnal and arboreal (lives in trees) mammal endemic to Indochina and Sundaland. These animals possess large membranes of skin called patagiums that extend along the limbs, allowing them to glide along distances of up to around 100 meters; given that these animals are only around 40 centimeters in length that's pretty impressive skills! The mottled coloring of these animals also makes them look a bit like the lichen of a tree and therefore helps to camouflage them. 
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.
