Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Porcupines are rodents with a coat of sharp spines, or quills, that defend them from predators. They are endemic in both the Old World and the New World. Porcupines are the third largest of the rodents, behind the capybara and the beaver. Most porcupines are about 25–36 in (63–91 cm) long, with an 8–10 in (20–25 cm) long tail. Weighing between 12–35 lb (5.4–16 kg), they are rounded, large and slow. Porcupines come in various shades of brown, grey, and the unusual white. Porcupines'' spiny protection resembles that of the unrelated erinaceomorph hedgehogs and monotreme echidnas.
