Hall  claimed that the North American porcupine (Erethizon dorsatum) possesses more than 30,000 quills. In this study, I counted 44,006 quills from a captive twenty-two year-old porcupine. The potentially large variation in the number of quills in E. dorsatum could be the result of body mass variation, sex, and diet composition.
