Why are porcupines quills so hard to remove?

The quills are designed to stay firmly embedded in the skin or surface they are lodged in. This is so the porcupine can defend itself against predators. Porcupine quills are barbed and have a small, spear-shaped tip. These barbs make it difficult to pull the quills out, and they can cause serious injury if not removed properly.

Additionally, porcupine quills are hollow, which makes them very light. This makes it even more difficult to pull them out, as they can easily break off and leave the barbed tip behind.

If you are ever stuck by a porcupine quill, it is important to seek medical attention immediately. A doctor will be able to remove the quills safely and reduce the risk of infection.
