With slender bodies covered head-to-toe in a dense, camouflaged fur 11million years in the making, it's no wonder leopards are renowned the world over for their ability to evade detection. 

Their camouflage, made up of pale yellow fur with brown spots, allows them to effortlessly stalk their prey in a massive range of habitats, including forests, grassland savannas, deserts, woodlands, coastal scrubs, mountains, and swampy areas. 

But while its quarry, often smaller mammals and even fish, rarely spot leopards until it is too late, human beings have developed keen enough eyes to spot predators like the leopard. 

These pictures below were taken by photographer Henri Olkers, who managed to find the elusive big cats in the Kruger National Park, South Africa. 

Can YOU spot the leopards hiding in these pictures? 

In the first photo, the leopard can be seen staring into the lens behind a small tuft of grass in the centre of the frame. 

Meanwhile in the second image, the big cat can be seen majestically looking out across the park while standing on top of a large rock, near the top of the image. 

Even though leopard print spots make the creatures stand out in a zoo, in the wild where there are lots of light and dark patches in quick succession more naturally - such as looking through long grass - the pattern is an evolutionary advantage.

This not only helps with hunting, but also helps protect leopards form the potential threat of bigger predators such as lions - which share their habitat and compete for the same prey.
