Many animals play hide and seek. Reptiles hide from their enemies by blending in with their surroundings. Quite a few have a body colour similar to their surroundings. The American vine snake looks and acts like lifeless twigs, vines or creepers. When you touch the snake, it drops to the ground and lies there like a dead twig. Other snakes also try this trick, Coral snakes and some other snakes move their tails. So they look like their heads.
Some reptiles are able to change their colour to match their surroundings. A reptile may be dark coloured when it lives on dark soil, and light coloured on light soil. The green lizard is a great example. Three kinds of old world geckos combine colour and form to escape the eyes of their enemies. They have greatly flattened bodies and tails, and bark like colour patterns. Natural protective colouring is known as camouflage.
