Researchers first saw lobtail feeding in 1980.

研究人员于1980年首次观察到这种“挑尾”捕食。

Those models assumed that humpback whales that spend more time with lobtail feeders were more likely to pick up the method themselves.

模型显示花更长时间进行“挑尾”捕食的座头鲸更有可能是自学的。

To create mathematical models for the spread of lobtail feeding, researchers used 27 years of data from whale-watching boats in the Gulf of Maine.

为了创建“挑尾”捕食传播的数学模型，研究人员利用了27年来在缅因湾赏鲸船上收集的数据。
