About the Cover
Cover: Rorqual whales lunge at high speed in order to generate the drag required to expand their buccal cavity around a large volume of prey-laden water, a process that presumably entails a high energetic cost and consequently limits maximum dive time. Goldbogen and colleagues (pp. 3712−3719) deployed digital acoustic tags on humpback whales to determine the kinematic and respiratory patterns of foraging dives. These data were integrated with the spatial distribution of prey to demonstrate how lunges are directed at the upper-most layer of dense krill patches. Photo by John Calambokidis.
