More to porcupines than quills

A walking pin-cushion. That’s usually what comes to mind when people think about porcupines. Even the word porcupine means “quill pig.” But there is so much more to learn about porcupines than their quills; their behavior and natural history is just as fascinating. For example, did you know that there are two main types of porcupines: old world porcupines, which are found throughout Africa, Europe and Asia, and new world porcupines, which live in both North and South America. Despite both being porcupines, they are unrelated to each other.
