Every week, Earyn McGee shares a fun game for her 16,000 Twitter followers. The PhD student at the University of Arizona's School of Natural Resources and the Environment is popular on Twitter as the creator of #FindThatLizard - a challenge that is exactly what it sounds like.
Ms McGee shares different pictures on the microblogging platform every week, all of them with a lizard (or lizards) hiding somewhere. The pictures can range from sweeping mountains to forest floors, vast canyons to rocky plains - all with one thing in common - they have a tiny reptile expertly camouflaged in them.
A few hours ago, Ms McGee took to Twitter to share a particularly challenging puzzle that left many Twitter users confused. The picture was clicked by palaeontologist Yara Haridy at the Dinosaur National Park and has a common sagebrush lizard hiding in plain sight.
Take a look and see if you can spot the lizard in this pic:
While some Twitter users managed to find the lizard quickly, others had a tough time.
"There's no lizard here... Just sticks that look like lizards..." wrote one person. "Took me a third search!" said another. "I really tried to #FindThatLizard, but it is EXTREMELY WELL-HIDDEN!!" a third exclaimed.
Were you able to find the lizard? If not, take a look below for the answer to this puzzle:
This is not the first time a camouflaged reptile has captured social media's attention. Australia's Sunshine Coast Snake Catchers last year shared a picture of a python hidden in a family's verandah and asked their followers to spot it.
