Animals use camouflage in various ways to protect themselves from predators or to hunt for prey. Some animals have colors or patterns that help them blend into their surroundings, making them less visible to predators or prey. Others may have body shapes or textures that mimic their environment, such as a stick insect resembling a twig. There are also animals that can change their color to match their surroundings, like chameleons. Camouflage is a survival strategy that helps animals avoid detection and increases their chances of survival in the wild.
