Average foraging lunges of Milky Way (left) and Edna (right). Both animals typically pitched upward (top panel, red line) until after the maximum speed was reached (middle panel) and then proceeded to angle down. During the last part of the upward pitch, Milky Way started rolling (top panel, blue line), a feature that was more variable and earlier in the lunge for Edna. During a lunge, the speed (middle panel, black line) showed a sharp increase and decrease for both animals. Both animals typically foraged at depth (bottom panel, green line), going up in the water column just before reaching maximum speed. Lines represent mean values, shaded areas around the lines show 5–95% confidence intervals.
