Animals use various methods to camouflage themselves in their environment. Some common techniques include changing their colors or patterns to blend in with their surroundings, such as chameleons or stick insects. Other animals mimic their surroundings, like the walking stick insect that resembles a twig. Additionally, some animals use disruptive coloration to break up their outline, making them harder to spot. Ultimately, animals adapt their camouflage techniques based on their habitat and predators to increase their chances of survival.
