Fig. 2. Individual, and individual by food type interaction effects. (A) Smoothed gape profiles of the four different individuals transporting a cricket. Note how individuals 6 (solid circles) and 7 (open circles) have higher gape distances during transport than individuals 9 (solid triangles) and 10 (open triangles) and how the total transport cycle duration of individual 7 is significant longer than that of the other individuals. (B) Smoothed gape profiles of the same individuals transporting an ant. Note how individual 9 (solid triangles) has a smaller gape distance during transport than the other individuals.
