Koi Fish Swim Bladder 0002

3D Volume Rendering Technique (VRT) reconstruction from CT scans in dorsal view of a whole Koi (Cyprinius carpio) demonstrating the position of the otoliths in the head. Otoliths are used to sense gravity and linear acceleration. Also visible are the skeleton, surrounding soft tissues (transparent), and swim bladder. Specimen courtesy of Michael Meyer.
