Porcupine
Orcupine, any of 25 species of large, herbivorous, quill-bearing rodents
 active from early evening to dawn. All have short, stocky legs, but 
their tails range from short to long, with some being prehensile. 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.
