Animals traveled slowly in high foraging success areas and dived shallower (17.2±8.0 kmday−1 and 53.6±33.1 m mean±SD respectively) than in low foraging success areas (51.0±13.1 kmday−1 and 81.8±56.2 m mean±SD respectively).

International audience Understanding food web functioning through the study of natural bio-indicators may constitute a valuable and original approach.
