A porcupine warns an enemy that gets too close by raising the quills on its back and clicking its teeth. If this doesn't work, the porcupine swings its spiky tail through the air. Sharp quills stab deep into an attacker's skin. Ouch! Fun text and eye-catching photos introduce this animal in all its gory glory.
