There are about 24 different species of porcupine. These species are found in various places all over Africa, Asia, North and South America, southern Europe, and even in the Phillipine Islands.
Common porcupines eat mostly bark, pine needles, grasses, nuts, and berries.
They also sometimes gnaw on bones and antlers sitting on the ground for minerals. Many North and South American porcupines spend some of their times in trees, while porcupines in other parts of the world live completely on the ground. The porcupine is a rodent, like mice and capybaras. Some may have more than 33,000 total. The common porcupine's front feet have four toes, the hind feet have five toes.
