托福口语 Task 4

Today, we're going to talk about a fascinating concept in animal behavior called 'biological mimicry'—specifically, when animals mimic not another species, but an object in their environment to avoid predators. This is known as 'masquerade.' Unlike camouflage, which blends an animal into the background, masquerade makes the animal look like something inedible or uninteresting to predators, like a twig, a leaf, or even bird droppings. Let me give you two examples. First, the stick insect. These insects have elongated bodies and legs that perfectly resemble twigs or branches. When they rest on a tree, predators like birds often mistake them for part of the plant and pass them by. Second, the orchid mantis. This insect has pink and white coloring that mimics a flower, specifically an orchid bloom. It sits motionless among flowers, and predators looking for prey may ignore it, thinking it's just a blossom. This strategy is highly effective because predators learn to avoid certain shapes or colors that don't seem nutritious. So, masquerade is a clever survival tactic that relies on looking like something a predator wouldn't want to eat.
