One of the wonders of the natural world is the ability of so many species to use camouflage as a defense mechanism against predators. Often, like we recently featured in this article on owls, camouflage means intricate patterns of brightly colored markings that help the animal to blend in with its habitat. In other cases, camouflage can mean transparency. Disappearing against the backdrop of your surroundings is easy if others can see right through you. Such is the case with the animals seen in this photo collection.
