Camouflage keeps many animals safe from predators, but some say the camouflage of Vietnamese mossy frogs is the most elaborate in the animal kingdom. Its uneven texture of bumps, along with the red, green and black montage of colors, appears to transform this frog into a clump of moss or lichen—blending flawlessly with its habitat. When frightened they fold into a ball and play dead. These frogs have sticky discs at the end of each toe, making them skillful tree climbers. Large eyes give them a broad range of vision.
