托福口语 Task 4

Today we're going to talk about a fascinating adaptation in the animal kingdom: camouflage that goes beyond simple color matching. I'm referring to what biologists call 'disruptive coloration.' The main idea here is that certain animals have patterns that break up their body outline, making it harder for predators to recognize them as a single, edible object. Let me give you two examples. First, consider the zebra. Its bold black and white stripes might seem conspicuous, but in a herd, these patterns create a confusing visual blur. When zebras move together, predators like lions struggle to single out an individual, because the stripes disrupt the animal's shape and make it blend into the moving mass. Second, think of the leopard. Its rosette-shaped spots, which are irregular dark patches with lighter centers, help it disappear into dappled sunlight and shadows on the forest floor. Even when the leopard is still, the spots break up its silhouette, making it look like patches of light and leaf litter rather than a solid animal waiting to pounce. So, in both cases, the pattern's primary function is not to match a single background color, but to hide the animal by disrupting its visible form.
