With their almost perfect camouflage, these animals are some of the Earth's best masters of disguise. However, while they can hide from their predators they cannot escape the sharp eyes of American photographer Art Wolfe, who has been on a quest to capture them on camera, since the early 1990's.

The Seattle, WA photographer says that finding and filming these clever animals is a painstaking process, one that often takes many hours. However for him, it is definitely worth the time because the thrill of capturing a creature that has managed to blend into its natural habitat so skillfully, is like none other.

His search has taken him to almost every continent in the world - From the deserts of Africa to the rainforests of South America and even, the snow plains of Canada.

Over the years he has snapped so many amazing photos that he has been able to showcase them in two books - A children's book entitled Hiding Out that was first published in 2003 and Vanishing Act, which first came to bookstores in 2005 - Both have been translated into several languages and been extremely popular all over the world.

And, he is not done yet. The 61-year old who also happens to be a television producer continues to unearth nature's beauties under lily pads, dissolved into tree trunks or stealthily awaiting their prey in the white snow! Would you have been able to spot any of them had you not known they were in the photographs? Be sure to let us know, by adding your comments below.
