FIGURE 3—Normal right side view of the pelvis, sacral vertebrae, and right femur, showing little effect of the condition seen on the left side. Phoiograpb by Morfon Boss. The cause of this anomalous condition was not determined. Although the bone damage resembles Pott's disease or tuberculosis of the spine as described for humans (Homans, 1932; Boyd, 1943), the lack of typical tubercular lesions in surrounding tissues and the lack of evi- dence of a primary lesion would seem to preclude tuberculosis as the cause. Actually, there are a number of conditions related to disease, nutrition, or injury which produce bone lesions without surrounding tissue reactions. Abnormal tooth wear on the anterior faces of the upper incisors and the tips of the lower canines (Figure 4) may indicate that this animal, no longer able to swim fast enough to catch fish, had been feeding extensively upon rock-dwelling mollusks. Similar tooth wear has been reported by Hildebrand (1954) for the sea otter, Enhydra lutris. This tAT3e of abnormal tooth wear, for the sea lion, has been noticed on skulls of carcasses of old California sea lion bulls that wash up on beaches of Ano Nuevo Island and vicinity. Perhaps due to old age or illness these animals resort to other means of food capture to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
