10、rillthe tiny crustaceans that they eat. Rather than finding where their prey (捕获物) currently is, they go after the places where their prey was in years past.

11、less species of animals migrate over long distances to exploit farflung sources of food, but these voyages arent just about getting to the final destination.

14、 pausing to gorge (狼吞虎咽) themselves on blooms of krill that appear along the way. Its a leisurely seasonlong tour of a continentwide buffet line.Scientists can get a good sense of this changing buffet by measuring the concentrations of chlorophyll in different patches of ocean. This green pigment (色
15、素) reflects the amount of plankton, which in turn is eaten by krill. The more chlorophyll there is, the more food a blue whale might find.By comparing chlorophyll counts to whale movements, Abrahms and her team expected to see that “they follow the timing of their prey, as it becomes available，” she
16、 says. But they were surprised to learn that the animals very rarely tracked contemporary waves of krill. Instead, their movements were strongly correlated (相关联) with 10year historical averages of chlorophyll. Put it this way: You could predict a blue whales movements with far more accuracy by looki
