托福口语 Task 4

Today, we're going to talk about a fascinating behavior in the animal kingdom called 'cooperative hunting.' This is when animals work together to catch prey, which they couldn't catch alone. The main point I want you to understand is that cooperative hunting requires complex communication and role specialization among group members. Let me give you two examples. First, consider lions. In a pride, lionesses often form groups to hunt zebras or wildebeests. They don't just all charge randomly. Instead, some lionesses act as 'wings' to drive the prey toward the center, while others, the 'center' hunters, wait hidden to ambush. Each lioness has a specific role, and they use low growls to coordinate their movements. Second, think of bottlenose dolphins. In shallow waters, a group of dolphins will circle a school of fish, creating a mud ring to trap them. Then, one dolphin at a time swims through the ring to catch fish, while others maintain the barrier. They use whistles and tail slaps to signal when it's their turn. So, in both cases, success depends on each member understanding its role and communicating effectively.
