How do porcupines defend themselves?

The quills on a porcupine's body are covered in sharp barbs, and when the animal senses danger, it will raise its quills in a defensive stance.

The porcupine will release its quill from its body and remain attached to its attacker, causing great pain and distraction. The attacker will experience more pain as it tries to remove the quills, which will ultimately lead to the porcupine escaping and the attacker learning a painful lesson. The quills will pierce the attacker's skin and the barbs will hold the quill in the attacker's skin.

Porcupines defend themselves by raising their quills, creating a deterrent for predators. When threatened, they may charge backward to stab the attacker with their sharp quills. Additionally, porcupines can release detachable quills, embedding them into the predator upon contact.
