Consist of most old-world porcupines; some of the largest rodentson planet!

Porcupines are large rodents with coats of very sharp spines known as quills. These quills protect them against a range of predators. These animals are present in Asia, Southern Europe, and most of Africa. These animals usually dwell in wooded areas; some can even spend their entire lives in the trees.

Generally, species of the genus Hystrix are herbivorous, eating roots, fruits, and bulbs. But some species have also been seen to gnaw on dry bones, possibly as a source of calcium. They are not of particular conservation importance, but they are hunted for quills sold in illegal markets worldwide.
