Figure 3


Fig. 3. Kinematic profiles of suction vs biting. (A) Frame from video during an in-water feeding (suction) trial with overlaid spatial model stick figure. (B) Plot of gape (cm) for a single suction feeding trial. (C) Plot of maximum gape angle velocity (deg. s–1) for a single suction feeding trial. (D) Plot of hyoid depression (cm) for a single suction feeding trial. (E) Frame from video during on-land feeding (biting) trial with overlaid spatial model stick figure. (F) Plot of gape (cm) for a single biting feeding trial. (G) Plot of maximum gape angle velocity (deg. s–1) for a single biting feeding trial. (H) Plot of hyoid depression (cm) for a single biting feeding trial.
