CAN you spot the deadly predator hiding in this rocky scene?
Optical illusion fans have been left scratching their heads trying to spot the puma stalking its prey among the rocks in this winter scene.
A wildlife photographer has created a ‘spot the puma’ challenge to test tour guides’ ability to recognise big cats camouflaged in the wild.
Snapper Greg Harvey, 51, struggled to see elusive pumas seamlessly blending into their surroundings but was impressed to find guides could often point them out.
So he clawed together a series of devilishly difficult images with three levels, Easy, Medium, and Hard, to test how eagle-eyed they really are.
