Fish Suction Power: Dynamic Digital Endocast
Swimming muscles power suction feeding in largemouth bass
Movie 3: Dynamic digital endocast used to measure change in mouth volume. The endocast (right) is of a 3D polygon fit to the shape of the mouth cavity, so that as the cranial skeleton expands (left), the polygon also expands and changes shape. Measuring the volume of the polygon at every frame provides the volume of the mouth cavity at each time step. This video has been slowed down 10 times from real-time.
