Porcupine quills are modified hairs made of keratin. When threatened, porcupines can erect these quills, which have backward-facing barbs.The barbs make it difficult for predators to remove the quills, causing pain and discouraging further attacks.The structure of porcupine quills serves as a natural defense mechanism, acting as a deterrent and protecting the porcupine from harm. | Science Of The Universe
