Why do porcupines have quills?

MammalsDefense

Quick Answer

Porcupines have quills for defense against predators. The quills are modified hairs with barbed or stiff structures that make them hard to remove.

The Full Story

Porcupine quills are an evolutionary defense rather than an offensive weapon. When threatened, a porcupine raises its quills to appear larger and more dangerous, deterring attackers before contact is made. In some species, the quills are barbed and can lodge in skin, making predators think twice about a second attempt. This strategy is especially important because porcupines are slow-moving herbivores.
