Porcupines are a widespread group of animals that inhabit almost every continent in the world except for Antarctica. They are divided into two families, old-world porcupines and new-world porcupines. The new world porcupines are mainly found in North America and some parts of northern South America.

A porcupines’ main defense is the quills, which they use to deter predators. Many people think that porcupine quills are poisonous. The quills of a porcupine are not toxic but can be extremely painful and cause injuries. Also, a porcupine cannot project or shoot out its quills towards the enemy as it was initially believed.
