Have you ever seen a porcupine? Compared to other Alaskan wildlife, the porcupine seems to be ignored, but talk to any dog owner and you'll likely hear some stories. Porcupines can weigh up to 30 pounds, making them the second largest rodent in North America (only the beaver is larger). Covering the porcupine's back and tail are quills, which are actually modified hairs. Porcupines do not throw their quills as some believe. These quills easily detach, but only through physical contact with a porcupine.
