See If You Can Spot What's Hiding In These 15 Photos

If you've ever encountered Where's Waldo as a child, these images will be a familiar challenge. However, they also might be a little harder at times (but in some cases, easier, too). But perhaps the best part of these is the fact that they're very real photographs from the actual world, rather than a puzzle that was drawn up by someone hoping to trick you. It turns out nature can make great puzzles, too, because in each of the following photos, an animal of some sort is hiding, often camouflaging almost perfectly.

These images will test your vision and attention to detail, and some of them are honestly pretty difficult. Make sure you're on a desktop or you can zoom in on your phone, because these might take a lot of patience to spot what's hidden in plain sight. When it comes to the tough ones, don't get too frustrated, either — just click on "answer" to see the solution to these puzzles.
