A large-bodied, slow-moving rodent having a unique natural defensive system - 30,000 quills. They are actually specially modified hairs.
Contrary to popular belief, porcupines cannot impale people, or thier pets, by "throwing" their quills through the air.
(Thank goodness - because that was in the back of my mind the whole time I was standing roughly 10 to 15 feet from this guy!)
