Abstract: The aim of present investigation was to study the anatomy of trachea and lungs of this rodent. For this purpose the cadaver of 3 porcupines that had been died in accidents, were dissected. The number of tracheal ring were 36 to 38. The tracheal ring were C shape and the dorsal part of them were filled by membrane. In Tracheal bifurcation, the terminal end of tracheal ring had been fell apart and the space had been filled with an elastic membrane. The right lung included cranial, middle and caudal lobes with the length of 93.3, 48 and 67.79 respectively. The cranial and caudal lobes had cranial, middle and caudal parts and the middle lobes had cranial and caudal parts. The left lung had cranial and caudal lobe with the length of 90.69 and 72.78 respectively. The cranial lobe had cranial and caudal part and the caudal lobe had cranial, middle and caudal lobes. In addition the length of right lung were larger than left lung. The result of this study revealed that although the porcupine in a member of rodent family, its respiratory system had its own characteristics.
