Over time animals have developed many ways to stay away from predators. A predator is an animal that hunts and eats other animals. Hiding is one of the best ways to stay alive. (1)______________________________. To see how this works, let's look at the sea dragon. It is a master of disguise. The sea dragon is covered with skin that looks like leaves. The skin helps the dragon look like a piece of seaweed. (2)______________________________. Other animals stay safe by showing their colors. They want other animals to see them. Scientists call these bright colors--warning colors. You have probably seen animals that have warning colors. (3)________________________________. Those colors don't just look attractive; they tell their enemies to stay away.
