porcupines

Hard to believe, but porcupines have on an average about 30,000 quills. These are really like their hair -- but when attacked, the porcupine responds by backing into the enemy and several of these quills just get stuck into the attacker's body, causing serious injury.

I often think we all know of people who take after the porcupine! They appear harmless - but when provoked -- boy, all those quills are quickly out to get you!
