  Porcupine - Wikipedia, the free encyclopedia
Porcupines in search of salt sometimes encroach on areas inhabited by people and eat tool handles, clothes and other items that have been coated in salty sweat.
A porcupine is any of 23 species of rodent belonging to the families Erethizontidae and Hystricidae.
All defend themselves with sharp spines (which are actually modified hairs) rather like those of the hedgehogs, which are part of the order Insectivora and more closely related to shrews and moles than they are to the rodents, and the echidnas, which as monotremes are very distantly related indeed.

The quills, or spines, take various forms depending on the species, but all are modified hairs embedded in skin musculature.
Old World porcupines (Hystricidae) have quills embedded in clusters, whereas in New World porcupines (Erethizontidae) single quills are interspersed with bristles, underfur, and hair.
No porcupine can throw its quills, but they detach easily and will remain embedded in an attacker.
