托福口语 Task 4

Today we're going to talk about a fascinating concept in animal behavior called 'biological mimicry,' specifically when an animal evolves to resemble an inanimate object or another organism to gain a survival advantage. This is not just about camouflage—it's about actively deceiving predators or prey. Let me give you two examples. First, the orchid mantis. This insect has evolved to look exactly like a pink orchid flower. It sits motionless on a plant, and when a pollinator, like a bee, comes to visit what it thinks is a flower, the mantis strikes and captures it. So the mantis uses its flower-like appearance to lure prey. Second, consider the mimic octopus. This marine animal can change its color and shape to imitate dangerous creatures, such as a venomous sea snake or a lionfish. When a predator approaches, the octopus shapes its body and moves in a way that mimics these threats, scaring the predator away. So in both cases, the animal's appearance or behavior is adapted to trick another species for survival.
