Giant Jellyfish Optical Illusion

I’m almost certain, there are no jellyfishes big as this one, in the picture below. Never the less, I can’t seem to figure out how this illusion took place. It would be easy if the scuba diver was behind, and the jellyfish was just infront of the camera, then “relative sizes illusion” would be possible. However, it seems that the diver is infront of the jellyfish (or is he?). Can someone help me solve this?

  1. Accroding to Wikipedia (http://en.wikipedia.org/wiki/Largest_organism):

    “The lion’s mane jellyfish is the largest cnidaria (jellyfish) species, with some attaining a bell diameter of 2.5 m (8 feet) and tentacles as long as 30 m (100 feet) or more.”

    Now, the jellyfish could be swiming towards the camera in some weird way, having 30 metres of tentacles behind it. The driver is only in front of the tentacles, not the jellyfish proper.

    That, or the picture is modified. :-)

  2. I’m thinking the diver is actually a reflection in a glass sheet… That would explain how the diver can be farther away, but appear in front of the jellyfish.

  3. thats totaly photoshop

    I manipulate pictures all the time

    this one was done pretty poorly

    the divers colors are off hue to the rest of the colors in the picture.

  4. I believe the image is altered, and more than photoshop is capable of doing such.

    The image _aa_ linked to is also obvisouly altered, quite interesting the area the diver is in doesn’t follow the pattern of the rest of the sea. Also it appears to be to circles at that, perahps over use of the cloner tool form a small area? There seems to be repeating pubbles comming from no where either. If you look slightly you’ll still see the divers case fadded in the tenticles.

    The article picture doesn’t, doesn’t mean anything though because there are many was of removing marks left by those programs.

    The linked picture mentions Adobe, and Ducky (I’ve seen ducky mentioned in anoter picture hmm…)

    the linked picture has had its levels changed and there has been some channel loss. There black areas are too black and couldn’t have the detail of the one posted.

    As for the original picture the diver seems more affected by light than the jellyfish. Also the case he is holding seems a bit sharp in contrast to the other object. Finally the guy seems way too close, if it was that big I don’t think he’d want to get that close for safty.

  5. Interestingly that link leads to an image with a suspiciously photoshop looking smudge like something has been removed and you can still see a little of the dark spot where the divers light(?) overlaps the tentacles. Stranger and stranger.

  6. I find it quite funny you can clearly see that the “original” _aa_ mentioned is (poorly) photoshopped from this optical illusion pic..

    The fact that the diver has lost it’s color but the jelly hasn’t is a dead give away of this not beeing a giant jelly. If it is photoshopped it’s not very well done. I’d like to think this is some kind of optical illusion. PS would be so boring.

  7. i agree with james, this looks nothing like a jellyfish. and loke, this picture looks nothing like the one on wikipedia.

  8. You beat me to it, Dave Goodman. Yes people, there really are jellyfish that are that big.
    This is no illusion. *shrugs*

  9. have you ever been in the ocean things fade out the farther away they are. now the diver and jellyfish are headed away from the camera. which means the jellyfish should be more faded than the diver. granded if the jelly fish is really that big then you would see some detail but the diver looks too faded compared to the jellyfish. definatly fake.

  10. There was a national Geographic post a while ago about giant jellyfish – The jellyfish is real and is in reality about half the size that you see it as. However, this IS photoshop.

  11. All of you guys are freaking annoying, OK, all that is needed is for a few people to say its photoshopped, not every f***ing person online jeeze. This site is supposed to be for ENTERTAINMENT not complaining how badly something’s photoshopped. ok, I’m done ranting

  12. i tink its not photoshoped
    yet not real
    it is a illusion
    i think
    and that diagram is a good way of discrbing it
    the reason the diver is so dark and not the shade of the jellyfish is because he is further away from the camera
    making him darker

  13. i’m not entirely sure but i have a sneaking suspicion that the this might be a Photoshop ‘altered’ picture…what do you reckon?

  14. Alright i see something else not having to do with the diver or anything. You see teh jellyfish where teh tentacles are attached to the head thing. Well i see a womans face blowing at the diver…anyone else see that? the tentacles look like her hair going from reddish to white…i think that should be the illusion not the diver.

  15. As a diver, former dive instructor, undewater photog…
    this is fake. No JF this big has ever been reported. If the diver is closer, he should be more colorful than the JF. Underwater, red fades out at about 12 feet from light source to subject to camera. Thus, the JF is only 6 – 8 feet from the camera. The diver is at least 30 – 40.

  16. Why tf has no-one considered the diver is a plastic toy?! Like, hung in the camera’s view on an invisible plastic string?

    I mean, it probably is photoshopped, but why hasn’t this plastic theory AT LEAST been considered?

    Somebody tell me if they had already before I mentioned it.

    Sorry, but . . . yeah.

  18. there is two BLATENT different light sources on this, making it obvious its fake! look how the light comes from the top left of the image (ie sea surface) but the diver is much darker, with a lot less polorization from the light, then the creator has obv tried to lighten the top of the diver, very badly!
    a big joke tbh

  19. The picture is actually real. Yes, nature is crazy and we know more about outerspace than our oceans, which is why there is not a lot of information on giant jellyfish, but if you simply google ‘giant jellyfish’ you can read about their sightings and captures off the coast of Japan, where their populations have surged as of recently. I think it’s sad that some people can’t just believe pictures anymore that we have to always assume something just beyond belief must be the work of some guy and a laptop.

  20. I believe that the “part” of the jellyfish that the diver is in front of is really a rock out cropping. Then it is a relative distance thing where the jelly fish is up close and the diver and rock is far back.

  21. I find it strange that people can’t believe things that have been proven to exist. Someone mentioned that this looks “nothing like a jellyfish on WikiPedia”. Unfortunately, WikiPedia isn’t always true. Don’t always assume that things as amazing as these are always photoshopped. It looks like a jellyfish, and for all we know it’s undocumented. Very strange creatures live in the oceans of the world. Don’t forget that.

  22. It looks like an optical illusion, bt I think it iz photoshoped cuz the diver’s camera/bag/box/wateva is infront of the “tenticals”, and there is no thing jellyfish THAT big, and if there was I would be friggen scared if it was a real one, cuz wat if it stung you, you would like die,! Owell, itz still quite kewl. Hahaha. Got me thinking…..

  23. If you examine the picture more carefully, then you can see that the jellyfish isn’t as big as you think… yes it is big but, however, if you stretch the diver, who is about 6′ then you still have about 1′ or 2 left on the jellyfish, so analytically speaking, this picture could be real.

  24. this jellyfish is actually areal jellyfish… its called the lion’s mane jellyfish, aka the BIGGEST jellyfish in the world. I should know… i am doing research on it… the biggest one found was 8′ in diameter of the bell and like 120′ long tentacles. soo it most likely is a real jellyfish picture. hate to break it to you. of course it only live in cold waters. that could be a good sign. :)

  25. No the diver and the jelly fish is suppose to be seen as the same distance but really the jelly fish is alot closer than the diver.

  26. it is a real jelly fish and that thing in the water is jellyfish poo! it only looks like a diver because the water pressure at that depth has altered it’s original poo form.

  27. it is obviously what doug said or a fantastic photoshop because if it is a real jelyfish not even a lunatic would get that close to it!

  28. wow…mitch is pretty wrong…uhh, the light is shining weird so all the colors look off. on myth busters a couple months ago, they were talkin about how the pix of the first moon landing were SUPPOSEDLY fakes, cuz the light and shadows were weird. HOWEVER, they figured out that the lighting from the sun was placed oddly and that the pik was genuine. i think itz just weird lighting and the pik is real :)

  29. I’ll chip in to this one – yes, it is a real jellyfish. I’m no expert but I’ve read about these things in hardcopy books on marine biology.

    I’m actually a bit surprised that people are so sceptical it exists. The ocean holds some phenomenally huge lifeforms, and jellyfish are hugely varied and abundant.

  30. Yes, it is a real jellyfish. The Lion’s Mane jellyfish are the largest in the world, with the body being several metres across and the tentacles being longer than a blue whale. I don’t know if this particular photo was photoshopped or not… I certainly wouldn’t want to swim near one… but it could very easily be real, since the Lion’s Mane jellyfish really ARE that big in comparison to a human being.

  31. I HAVE BEEN TO THE BEACH BEFORE AND SAW A JELLY FISH AND I THOUGHT IT WAS PREEETY BIG BUT THATS SOOOOOOOO HUUUUUUUUUUUUUUUGE!!!!!!!!!!!!!!

  32. Blow the picture up real big and you can clearly see the blurred blending around the diver. The diver has been photoshopped in and it’s a pretty good job but there will always be that tell tale halo.

  33. Jeez, guys… take two seconds to read just a bit, and you can see how this pic is very easily not a fake.

    “The Arctic Lion’s mane jellyfish is one of the longest known animals; the largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and tentacles 36.5 m (120 feet) long. ”

    If you stretch out that diver to his full height (He is semi-facing away, and looks very small), you can see that the jellyfish isn’t vastly bigger than him.
    Plus, if it’s a short diver, the jelly would look bigger still.

  34. omg if you guys think its fake Ur wrong. if you think its zoomed closer to the camera then look at how many tentacles it has !

  35. That’s a real jelly. And it’s not shopped either. Jellyfish of tht size exist and a few have been documented, however I don’t expect them to be all over the Internet due to some people’s willinglessness to believe in what is real.

  36. Well, the jellyfish is real–but not really that big. It’s not an illusion, it’s photoshopped. :) There ARE enormous jellyfish, but none so big as this. What I believe some of you don’t realize is just how AMAZING some artists are with nothing but two pictures and photoshop.

    Let me also explain this: just because the jellyfish is big doesn’t mean it’s more deadly than a smaller one. The deadliest jellyfish in the world is the box jellyfish and can be smaller than the human eye can perceive unaided.

    1. This is the Lions Mane jelly. They can grow as large as a blue whale. This is real not illusion.

  37. That last post is the photo shopped one. You can clearly see the smear marks from where the the diver was. Even if this particular photo was forced perspective, there are lots of different photos on the internet of the lion’s mane jellyfish which show the creature’s incredible size.

    Watch some Nature of Things documentaries on the oceans. There are some incredible, almost alien creatures living down there.

  38. dont be stupid.. you look at both pictures and can see the photoshop blurr on the one without the diver.. some of its tentacles are missing in the shape of what hes holding, the tip of the bubble stream can also be seen above the blurred patch in the “non diver” image.. someone has just been too stubborn and close minded to admit there wrong that they made one image look photoshopped while trying to erase the evidence of the diver… grow up

  39. all you have to do is google giant jellyfish and hit the images button in the top left corner to know that this has a true possibility of being a real pic
    or go to http://www.dailymail.co.uk/news/article-1180558/Pictured-The-giant-jellyfish-washed-Devon–big-make-wobbly.html and try and picture it in the ocean so it would be all sprawled out obviously not all floppy like this one, and then take into consideration that the largest documented jellyfish is The lion’s mane jellyfish it is the largest known species of jellyfish. The Arctic Lion’s mane jellyfish is one of the longest known animals and the largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and the tentacles reached 36.5 m (120 feet). It was found washed up on the shore of Massachusetts Bay in 1870

    also see this site its kinda wicked

    http://twistedsifter.com/2009/06/10-amazing-facts-about-jellyfish/

  40. it might be in an aquarium and the diver is in a tank and the jelly fish is on a projetion screen behind him

  41. it’s 100% real and there are jellyfish 100 times bigger, more people have been to the moon than the bottom of the ocean

  42. The fact that there are possibly millions of creatures out there that explorers and scientists haven’t found yet, should make people open minded when it comes to what is real and what is not. there are even still tribes in third world countries that know nothing of modern technology and when people fly over their tribe to take photos they will actually try to spear you down thinking you are a creature of threat.

    ANYWAY…. here is another website that contains the same photo as above.

    http://www.freerepublic.com/focus/chat/2501004/posts

  43. the answer to it is just like the same as said on web itself, “sometimes its good to believe that god exists coz every answer is not found on google”

  44. it’s the lion’s mane jellyfish the biggest one in the world… the biggest lion’s mane jellyfish has tentacles bigger than the biggest blue whale ever and it IS real

  45. http://www.waterford-today.ie/index.php?option=com_content&task=view&id=933&Itemid=10177&ed=68

    Though it’s been said. To quote:

    “The largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and the tentacles reached 36.5 m (120 feet).”

    That one was only measurable because it washed up on the shore. They could easily grow to larger sizes.

    Fun fact: Jellyfish are over 90% water.

    Also, Lion’s Mane are rarely fatal. So the dude is fairly safe.

    Tl;dr: The Jellyfish is real.

    QED

  46. its a real jellyfish
    the diver is far away. he is not holdin any camera or othe objects. this seems like an old photo for me. so, i assume dat dis photo has a black smudge dat appears as da camera. and dat da jellyfish is close. it took me 5 minutes to come up with the answer because im a th grader i assume. it has been proven dat children tend to have ideas faster dan adults and can easily answer illusions.

  47. its real, this creature is found off the eastern coast of japan. i do believe this is the largest ever photographed but they are very large

  48. dis photograph looks old and in my knowledge, old pics sometimes get black spots. da “camera” da diver is “holding” is actually one of da dots im talkin about. da diver is far away and da jelly fish(normal size) is very close to us appearing to be a giant.

  49. I have seen this image before. It is definitely real. The diver is no further away than the jellyfish, and the camera is just a camera.

    Isn’t nature amazing? (but kinda freaky)

  50. its not real…its called photoshop der…people play pranks like this all the time…jesica..learn how to spell “the”

  51. Lion Jelly fish can get really big yes, google them first, they dont get THAT big though… the diver is further away then the jelly and makes the jelly look bigger then it really is. However Lion Jellies do get REALLY BIG

  52. Although Lions Mane jellyfish can grow to huge sizes, this photo is obviously photoshopped as the colour of the light reflecting off of the diver is completely different to the light on the jelly fish

  53. While it may be Photoshopped, this could be real if the Wiki article is to be believed. The largest specimen ever found was 6’5″ across the dome and tail of 120 feet. The diver is only in the foreground of the tail which if it were just 30-40 feet long, could place the diver much farther away from the camera than the dome of the fish.

  54. I think it is photoshopped because, to capture the allegedly huge jelly fish, the camera would have to be placed very far away. However, sea water is not very transparent (at least in this case) and will not allow such a sharp picture to be taken from a distance.

  55. @Elizabeth — the photo you submitted for “proof of photoshopping” actually just looks like the diver was erased. The background is drastically different where the diver used to be.

  56. The lion’s mane jellyfish can attain enormous size. In fact, the largest Lion’s Mane jellyfish is not merely the largest species of jellyfish in the world; it is the largest animal in the world. The one specimen of Lion’s Mane which was found in Massachusetts Bay in 1870 was over 7 feet in diameter and its tentacles were longer than 120 feet in length. However, the bell of the Artic Lion’s Mane is known to be able to grow up to 8 feet in diameter, and their tentacles can acquire the length of 150 feet. That is much longer than blue whale, which is generally thought to be the largest animal in the world.

  57. The lion’s mane jellyfish (Cyanea capillata) is the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans, seldom found farther south than 42°N latitude. Similar jellyfish, which may be the same species, are known to inhabit seas near Australia and New Zealand. The largest recorded specimen found, washed up on the shore of Massachusetts Bay in 1870, had a bell (body) with a diameter of 7 feet 6 inches (2.29 m) and tentacles 120 feet (37 m) long.[1]

  58. King of War I think. it is one of the more believed in crypteds it has not yet been proven but there is strong evidence behind its existence.

  59. I see three objects,
    Main object – Jellyfish
    Backround object – Diver
    Foreground object – What looks like could be a snail or something, but shaded the same as the diver so it appears it’s in the backround with the diver.

  60. I happen to know that this is a a real photo it was studied scientifically and it has a name witch I forgot but it is real
