| The Porcupine has its upper parts covered with thousands of sharp, barbed hollow spines or quills, which are used for defense. Porcupines do not throw their quills, but the quills detach easily and the barbs make them difficult to remove once lodged in an attacker. The quills are normally flattened against the body unless the animal is disturbed. The porcupine also swings its quilled tail towards a perceived threat. |
