托福口语 Task 4

Today, I want to talk about a fascinating concept in biology called 'mimicry', specifically how some animals use mimicry not just for camouflage or predator avoidance, but also for hunting. The main point is that mimicry can be an active hunting strategy, not merely a passive defense. Let me give you two examples. First, consider the anglerfish. This deep-sea creature has a fleshy growth on its head that glows, mimicking a small, bioluminescent worm. Smaller fish are attracted to the light, thinking it's a meal. When they get close, the anglerfish snaps them up. Second, think about the alligator snapping turtle. It has a pink, worm-like appendage on its tongue. When the turtle lies still in murky water, it wiggles this appendage. Hungry fish mistake it for a tasty worm and swim right into the turtle's open mouth. In both cases, the predator uses a false signal to lure prey, turning a potential weakness into a powerful hunting tool.
