We have gathered a collection of 13 astonishing photos. They will show you that, no matter how experienced you are, you still haven't seen it all. These are photos of extreme conditions, rare genetic mutations, moments before a big event, and the unseen sides of ordinary things. They will answer questions you may have had about life, like, "What does a tiger's skin look like?" and make you ask different questions, such as, "If that's what salt looks like under the microscope, then what would pepper look like?" Take a peek at the parallel world shown in these photos, and head over here for a second serving of amazing natural phenomena.
