Nature is an amazing thing, and we'll always be in awe at how animals have adapted to blend in with their environments through years of evolution.
One of these ways is through camouflage, and there's one image circulating round the internet today which proves how effective it can be.
But can you spot the leopard hiding in this photo?
Yep, us neither at first - but trust us, there's one in there.
The mind-boggling photo was posted on Twitter this weekend with the original poster explaining it has been sent to her by a friend - and at first, she thought they were pulling her leg.
"Someone just sent this to me and asked me to find the leopard. I was convinced it was a joke... until I found the leopard. Can you spot it?," she wrote.

It's since been causing quite the stir with people desperate to spot the big cat - and others rejecting the idea its there altogether.
"No, but now I am getting a headache," said one commenter.
"I would be extremely dead before I spotted it," said another.
"Someone please pm me the answer. I'm gonna go crazy if I stare at this dirt anymore," begged a third.
"This is definitely not a leopard, mere stones," another was convinced.
Like, we for one love an optical illusion - but this one is really taking the biscuit.

See it? Right there in the ditch, just north of that tree branch in the fore of the photo.
If you spotted it before, congrats. If you (like us) were convinced we were just being told to stare at a pile of stones, here's a closer look...
Despite the viral photo being a bit of fun, the most-liked comment in the replies rang true: "Unfortunately in a few years time people won't be able to play this game as there won't be any Leopards to spot!"
Research from 2016 found that leopards had lost 75 per cent of their historical habitat over the last 250 years.
"We found the leopard had lost 75 per cent of its historical habitat, we were blown away by that, it was much more than we feared," said Andrew Jacobson, a conservationist at the Zoological Society of London and lead author of the study.
