Erethizontidae is the family of New World porcupines. These porcupines are generally arboreal, meaning they spend much of their time in trees. They are found in North and South America and are characterized by their quills, which are barbed and easily detach. Think of them as the tree-dwelling guardians 🌳 of the porcupine world. These barbs help the quills embed deeply into predators. They play an important role in forest ecosystems by pruning trees.
