Movie 2

Animation of skeletal kinematics and buccal cavity volume during a sample bluegill sunfish suction feeding strike (antero-lateral view). Buccal volume was measured with a dynamic digital endocast (green and yellow polygon), which is shown with the animated bone models (left) and by itself (right). The motion of both the endocast and the bones are viewed relative to the body plane, i.e., the motion of the fish's body. The animation was created from X-ray videos filmed at 500 Hz, but it has been slowed down about 30 times in this movie.
