The skulls and brains of 19 northern fur seals (Callorhinus ursinus) were studied. These animals had been rendered unconscious by blunt head trauma as part of the harvest procedure on the Pribilof Islands of Alaska. All seals had depressed, comminuted fractures of the skull. Epidural, subdural and subarachnoid hemorrhage were frequently present. In addition, the brains showed varying prevalence and degrees of laceration, superficial contusion and hemorrhage in deep midline or paramedian structures and ventricular system. Lesions observed were related to the head trauma.
