Animation of 3D bone models from X-ray Reconstruction of Moving Morphology (XROMM) during a sample bluegill sunfish suction feeding strike. The animated bones are the neurocranium and cranial bones from the left side of the head, with their medial sides shown here in oblique right lateral view. Also shown are the biplanar X-ray videos from which these motions were reconstructed. The X-ray videos were filmed at 500 Hz, but have been slowed down about 30 times in this movie.
