Fig. 6

Prey capture shown in white shark stomach tag data detail. Data detail showing the rapid ascent (a) from 28 m to the near-surface associated with elevated ODBA. The corrected X, Y, and Z accelerometer traces (b) show the surge (blue), sway (red), and heave (green), respectively, enabling detailed reconstruction of the event. Oscillations in the swaying acceleration (red) reflect the tail beat frequency and amplitude. The location of the three X and Y traces relative to 0 g and the Z trace relative to −1 g reflect the body orientation. For example, during the peak of the ascent the shark was nearly vertical. The ODBA trace (c) reflects an integrated measure of active acceleration. Note that ODBA was elevated during the burst ascent, and sustained at a higher level for an additional 30 s after the peak of the ascent, consistent with a struggle with a relatively large prey
