托福口语 Task 4

Today we're going to talk about a fascinating adaptation in the animal kingdom: camouflage. But not just any camouflage—we're focusing on what biologists call 'disruptive coloration.' This is when an animal's markings break up its outline or shape, making it harder for predators or prey to recognize it as a whole. The key is that the pattern creates false boundaries and shapes, so the animal seems to blend into the background. Let me give you two examples. First, consider the zebra. Its black and white stripes, when in a herd, create a confusing, moving pattern that makes it difficult for a lion to single out one individual. The stripes disrupt the visual continuity of the herd, causing predators to lose focus. Second, think about the leopard. Its spots mimic the dappled light and shadow of the forest floor. The spots break up the leopard's solid body shape, so when it lies motionless, it looks like just patches of sun and shade, not a predator. So, in both cases, disruptive coloration helps the animal survive by confusing the observer's perception of its shape.
