Porcupine Quills

From the USFWS National Wildlife Refuge System:

Contrary to popular belief, a porcupine can’t shoot out its barbed quills in self-defense. But when it’s threatened, it shakes its body and flicks its tail, and loose quills fly. If you’re too close, you’ll feel them. If you’re lucky, you might see (but not feel) a “quill pig” at Seedskadee National Wildlife Refuge, WYhttp://1.usa.gov/17e1Dlz Photo: Courtesy of Roger Leitner
