托福口语 Task 4

Today, we're going to talk about a fascinating concept in animal behavior called 'behavioral adaptation.' This refers to how animals develop specific behaviors over time to survive in their environments. One key point I want to emphasize is that these adaptations are often triggered by environmental pressures, such as food scarcity or predation. Let me give you two examples. First, consider the desert kangaroo rat. In its arid habitat, water is extremely scarce. To survive, it has adapted by not drinking water at all. Instead, it gets all the moisture it needs from the seeds it eats, and it has highly efficient kidneys that produce very concentrated urine to minimize water loss. Second, let's look at the arctic fox. In the snowy tundra, finding food is challenging. Its behavioral adaptation is to follow polar bears at a safe distance. When a polar bear catches a seal and leaves scraps, the arctic fox scavenges on the remains, ensuring a reliable food source during harsh winters.
