Phoca vitulina
3D Shaded Surface Display (SSD) reconstruction of air pathways from CT scans of the auditory canals of a live Harbor Seal (Phoca vitulina). Solid structures in the image represent air. The left auditory canal is foreshortened and does not connect with the middle ear because it has been blocked by scar tissue as a result of a chronic infection. Specimen courtesy of New England Aquarium (NEAq).
