托福口语 Task 4

Today, we're going to talk about a fascinating concept in animal behavior called 'behavioral flexibility.' This refers to an animal's ability to adjust its behavior to new or changing situations, rather than relying on fixed instincts. Behavioral flexibility is crucial for survival when environments change unexpectedly. Let me give you two examples. First, consider the raccoon. Raccoons are known for their ability to adapt to urban environments. In the wild, they forage near streams for food, but in cities, they have learned to open trash cans and even doors of houses to find food. This adjustment is not instinctual; it's learned through trial and error, showing flexibility. Second, think about the octopus. In laboratory settings, octopuses have been observed changing their hunting strategies based on the type of prey. For instance, when facing a slow-moving crab, they might pounce directly, but when encountering a fast shrimp, they use a more cautious, stealthy approach. These adjustments demonstrate how octopuses modify their behavior in response to specific challenges. So, in both cases, behavioral flexibility allows these animals to thrive in diverse or changing conditions.
