Alewife Swim Bladder 0001
3D Shaded Surface Display (SSD) reconstruction from CT scans of an Alewife (Alosa pseudoharengus) demonstrating the swim bladder (large elongated object) and otoliths (two small objects near the top of the head). The swim bladder is a gas filled organ that facilitates buoyancy control while the otoliths are used to sense gravity and linear acceleration.
