"Nature red in tooth and claw", said Alfred Lord Tennyson.
For, out there in the vast and unforgiving expanses of the wild, life is simply currency to be circulated amongst its participants. Yet, the natural order does not always entail the ultimate triumph of size, speed and muscle power. In fact, over the billion years of Earth's evolution, it is the the smaller creatures that have somehow managed to scrape through and survive, while the gigantic and magnificent are often interred and ultimately converted into fossil fuel, ironically, to power modern human ambitions. One of the techniques that have held the following often overlooked survivors and hunters in good stead is the ability to become one with its surroundings. The fascinating and often deadly trick of camouflage is one of Nature's most perfect genetic ornamentations, and these 20 creatures have mastered the art.
