Animals use coloration for camouflage and protection in various ways. Some animals have evolved color patterns that help them blend into their surroundings, making it difficult for predators to spot them. This camouflage can be in the form of stripes, spots, or patterns that match the environment they live in. Other animals use bright colors as a warning signal to predators that they are toxic or dangerous to eat. For example, poison dart frogs have vibrant colors to warn predators of their toxicity. Additionally, some animals can change their color to match their surroundings, such as chameleons, allowing them to blend in and avoid detection.
