Fig. 1. Representative profiles of gape kinematics (open diamonds), the distance
between the center of the predator's mouth and the prey (grey triangles), and
the force exerted on the prey (closed circles) in largemouth bass (A) and
bluegill (B). In largemouth bass, the distance between the predator and the
prey is closed by swimming towards the prey from a distance. In bluegill, that
distance is closed through jaw protrusion after a period of minimal ram (time
0–20 ms in B). Shaded area represents negative predator–prey
distance, i.e. the prey is in the mouth. Note the different force scale in A
and B.
