托福口语 Task 4

Today, we're going to talk about a fascinating behavior in the animal kingdom called 'mimicry.' Specifically, I want to focus on 'aggressive mimicry,' where a predator uses a disguise to lure its prey. The key point is that aggressive mimicry involves looking or acting like something harmless or even attractive to the prey, which reduces the prey's wariness. Let me give you two classic examples. First, consider the anglerfish. It lives in the deep, dark ocean where light is scarce. It has a fleshy growth on its head that glows, acting like a lure. Smaller fish, attracted to the light, swim close thinking it's a tasty snack. But as soon as they get near, the anglerfish snaps them up. Second, think of the orchid mantis. This insect has a body that mimics a beautiful pink or white orchid flower. It sits motionless on a plant, and when a pollinating insect like a bee or butterfly comes to investigate the 'flower' for nectar, the mantis quickly grabs it. In both cases, the predator exploits the prey's natural attraction to food or safety, proving that aggressive mimicry is a highly effective hunting strategy.
