Flipper strokes can predict energy expenditure and locomotion costs in free-ranging northern and Antarctic fur seals
International audience Flipper strokes have been proposed as proxies to estimate the energy expended by marine vertebrateswhile foraging at sea, but this has never been validated on free-ranging otariids (fur seals and sea lions).Our goal was to investigate how well flipper strokes correlate with en...
