Figure 1

(A) Image of sperm whale 199b tagged in 2005 off northern Norway. The figure shows the tag position at the moment of deployment. (B) Section of a dive profile recorded from a male sperm whale off northern Norway. The colour indicates approximate swim speed estimated using a Kalman filter matching pitch angle to depth rate. This estimate loses accuracy at low pitch angles. Each grey circle marks a prey capture attempt (buzz). (C) Roll orientation of the diving sperm whale during the foraging dive. Distribution of the absolute roll angle during the foraging phase of pooled (D) shallow dives, depth <220 m (n = 31, 3 whales), and (E) deeper dives (n = 64, 6 whales). Coloured bars denote different animals.
