Here's a brain teaser for you - can you spot the leopard camouflaged in the above photo?
The viral picture, posted on Twitter earlier this year, shows a leopard whose camouflage is so effective that it's near-impossible to spot it in the dirt.
In what might be the most difficult edition of Where's Wally?, thousands of social media users struggled with the challenge of spotting the big cat.
The Twitter user uploaded the image while admitting that when her friend sent it to her, she thought they were taking the p**s.
She said: "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?"
The picture sent her 150,000 followers into meltdown, with the post garnering well over 1,600 comments at the time of writing.
One user wrote in desperation: "Someone please pm me the answer. I'm gonna go crazy if I stare at this dirt anymore."
Another wrote: "Took me too long. Leopard would've got me," while a third added: "Took me about 5 minutes!! Well hidden... more of this please."
For those of you who are due a trip to Specsavers, despite the additional comment of "PLEASE DON'T POST THE ANSWER," a number of people have shared spoiler photos with arrows or circles outlining the well-hidden creature.
To be fair, I'm 99 percent certain I wouldn't have been able to spot it if it weren't for the help of the Twitter community. If you're the same, check out the answer below...
Incredible, right? No doubt the wily leopard's prey didn't even see it coming.
While the picture challenge was a bit of innocent fun, the diminishing number of certain species across the globe is cause for alarm.
As outlined by the the Born Free Foundation website: "Wild leopards are under threat, largely due to human pressures and habitat loss, while captive animals suffer in zoos, circuses and under private ownership."
It doesn't help when you've got poachers killing off the remaining rare animals in their natural habitat.
With charities such as Born Free, you can help the issue by supporting the organisation in a myriad of ways in their quest to ban trophy hunting and protect leopards in both the wild and captivity. You can donate to the charity here.Featured Image Credit: Hemant Dabi
