National Geographic is proud owner of some of the best photos in the world. Here and then a photo jumps out, containing an interesting effect which sometimes can be seen as optical illusion. Just check out this National Geographic tag, and you’ll be amazed how many illusions on this site are from NG. Anyway, today’s optical illusion was submitted by Urban Ambrozic and Grégory Plantard. We get many of “camouflage” illusions, but most of them don’t make it to the front page of Moillusions. This one however, took my attention. First I only saw one campuflaged toad – thought : “hm, its ok”, but after few moments I was able to spot the second and third one! How many of them are there?! Those three leaf-litter toads were collected within yards of each other, and its amazing how they almost disappear on a forest floor in Panama. For them to stay alive in the tropics (where nearly everything is food for something else), often calls for such trickery to fool a predator’s eye. Below the photo, you may see a gallery of few similar photos (by NG as well). Can you spot an insect hiding in each of them? Those little animals could very well put Liu Bolin and Emma Hack to a shame. Amazing!
