Prickly Porcupine Rattling Fact
On average, porcupines have as many as 30.000 quills covering their entire bodies. Their bellies, faces and inner limbs are not covered. Normally, when the animal feels relaxed, these quills lay flat. However, when it feels threatened the quills stand on end, to warn off potential attackers. If a porcupine puts up its quills, this makes a rattling sound similar to a rattle snake’s.
