Stare at these pictures for long enough and you might just spot some clever creatures playing the ultimate game of hide and seek.
This Satanic Leaf-tailed Gecko is barely visible against the leaves in the Andasibe-Mantadia National Park, Madagascar.
These amazing animals are true masters at blending effortlessly into their environment as a means of survival in the natural world.

From frogs to fish and bugs to birds, this collection of images shows the animal kingdom's outstanding camouflage ability.
Animals use two basic methods of concealment in a bid to hide from predators and catch prey.
These are general resemblance and special resemblance.

With general resemblance animals use colour to blend in with their background until they are almost invisible.
This method is commonly associated with chameleons but other creatures, including spiders and the Hymenopus Coronatus or Orchid Mantis, adopt this tactic when hiding and hunting.
Special resemblance sees creatures use a mixture of shape, colour, texture and behaviour to make them appear like something else in their habitat, such as a leaf or twig.
